Therefore, it is vital that sufficient heat sinking is provided, or the life and switching reliability of the SSR will be compromised. The SSR-HS-1 heat sink maximizes heat dissipation and helps ensure reliable operation when properly selected for the specific application. For ease of installation, all mounting holes are pre-drilled and tapped.

particularly heat/cool temperature control, motors, lamps, solenoids, valves, and transformers� The list of applications for the SSR is almost limitless� ## **Typical Examples of SSR Applications** Electronic Appliances Industrial Heater Control _Domestic appliances, cooking appliances, Plastics industry: drying, extrusion/thermoforming, heating elements, audio equipment heat tracing, solder wave/reflow systems, car wash pumps and dryers_ Food & Beverage Lighting Control _Commercial/industrial cooking equipment, Traffic signal systems, motorway information filtration systems, bottleing, chillers, systems, theatrical lighting convection ovens_ se, High Reliability Mining _Medical equipment, lifts & escalators, low Blower control, motorized duct/vent control, switching noise, low electromagnetic drill control, explosive control, mineral extractors interference, automatic door operation_ os HVAC & Refridgeration Oil & Gas _Anti-condensation equipment, compressor Burner assemblies, chemical injection systems, control, blower control, motorized duct/vent extraction machines, refining machines, control solenoid control_ ae Industrial Appliances Packaging _Industrial cleaning equipment, commercial Conveyor motors, heaters, product/shrink wrap, coffee machines, commercial/industrial solenoid control cooking equipment_ we Idustrial Automation _Automotive assembly plants, conveyance, motor control_ 25 _Application Data (continued)_ ## **Magnecraft[®] Solid State Relays** ## **Thermal Considerations** One of the major considerations when using a SSR is properly managing the heat that is generated when switching currents are higher than 5 A� In this scenario mount the base plate of the SSR on a good heat conductor, such as aluminum, and use a good thermal transfer medium, such as thermal grease or a heat transfer pad� Using this technique, the SSR case to heat sink thermal resistance is reduced to a negligible value of 0.1 ˚C/W. ## **Thermal Calculations** To understand the thermal relationship between the output semiconductor junction (TJ) and the surrounding ambient temperature (TA) measure the temperature gradient, or drop of temperature, from junction to ambient (TJ - TA); which equals the sum of the thermal resistances multiplied by the junction power dissipation� **TJ - TA = P (RөJC + RөCS + RөSA)** Where: **TJ** = Junction Temperature, °C **TA** = Ambient Temperature, °C **P** = Power Dissipation (ILOAD 3 EDROP) watts **==> picture [231 x 40] intentionally omitted <==** To use the equation, the maximum junction temperature of the semiconductor must be known, typically 125 ˚C, along with the actual power dissipation. When these two parameters are known, the third can be found as shown in the following example: **1)** Determine the maximum allowable ambient temperature, for a 1 ˚C/W heat sink and a 10 A load (12 watts) with a maximum allowable junction temperature (TJ) of 100 ˚C, and assume a thermal resistance from junction to case (RөJC) of 1�3: **==> picture [247 x 38] intentionally omitted <==** **2)** Determine the required heat sink thermal resistance, for 71.2 ˚C maximum ambient temperature and a 10 amp load (12 watts): **==> picture [145 x 74] intentionally omitted <==** **3)** Determine maximum load current, for 1 ˚C/W heat sink and 71.2 ˚C ambient temperature: **==> picture [267 x 76] intentionally omitted <==** 26 ## _Application Data (continued)_ ## **Magnecraft[®] Solid State Relays** ## **Heat Sinking** Thermal management is a fundamental consideration in the design and use of solid state relays because of the dissipation (typically 1 watt per amp)� It is, therefore, vital that an adequate heat sink is provided, or the life and switching reliability of the SSR will be compromised� In order to properly size a heat sink one has to consider the variables that comprise the thermal resistance Rth (in °C/W)� **Tr:** Temperature rise **Ta:** Ambient temperature (example 22 °C) **Th:** Heat sink temperature (example 54 °C) **Vh:** Voltage to heater (example 12 V) **Ih:** Current to heater (example 3�5 A) **Ph:** Power applied to heat sink **Rth:** Thermal resistance (in °C/W) Therefore: **Tr** = Th – Ta = 54 – 22 = 32 °C **Ph** = Vh 3 Ih = 12 3 3�5 = 42 W **Rth** = Tr ÷ Ph = 32 ÷ 42 = 0�76 °C/W Now that we have calculated the thermal resistance (Rth) we can look at the thermal resistance vs� heat sink volume curve� **Thermal Resistance vs Heat Sink Volume** _Natural convection at 50 C rise above ambient_ **==> picture [269 x 192] intentionally omitted <==** **----- Start of picture text -----**<br> 10<br>1<br>0.1<br>0.01<br>10 100 1,000 10,000 100,000<br>HEAT SINK VOLUME (cm [3] )<br>(ºC/W)<br>THERMAL RESISTANCE OF SINK TO AMBIENT<br>**----- End of picture text -----**<br> Using this curve with our example above, we can see that a heat sink volume of approximately 1000 cm[3 ] would be needed to successfully sink the amount of heat generated by the device� 27 _Application Data (continued)_ ## **Magnecraft[®] Solid State Relays** ## **Load Considerations** The major cause of application problems with SSRs is improper heat sinking� Following that are issues which result from operating conditions which specific loads impose upon an SSR� Carefully considered the surge characteristics of the load when designing an SSR as a switching solution� ## **• Resistive Loads** Loads of constant value of resistance are the simplest application of SSRs� Proper thermal consideration along with attention to the steady state current ratings is important for reliable operation� ## **• DC Loads** DC loads are inductive loads� Place a diode across the load to absorb surges during turn off� ## **• Lamp Loads** Incandescent lamp loads, though basically resistive, require special consideration� Because the resistance of the cold filament is about 5 to 10 percent of the heated value, a large inrush current can occur� It is essential to verify that this inrush current is within the surge specifications of the SSR� One must also check that the lamp rating of the SSR is not exceeded� This is a UL rating based on the inrush of a typical lamp� Due to the unusually low filament resistance at the time of turn-on, a zero voltage turn on characteristic is particularly desirable with incandescent lamps� ## **• Capacitive Loads** These types of loads can be difficult because of their initial appearance as short circuits� High surge currents can occur while charging, limited only by circuit resistance� Use caution with low impedance capacitive loads to verify that the dl/dt capabilities are not exceeded� Zero voltage turn on is a particularly valuable means of limiting dl/dt with capacitive loads� ## **• Motors and Solenoids** Motor and solenoid loads require special attention for reliable SSR functionality� Solenoids have high initial surge currents because their stationary impedance is very low� Motors also frequently have severe inrush currents during starting and can impose unusually high voltages during turn off� As a motor’s rotor rotates, it creates a back EMF that reduces the flow of current� This back EMF can add to the applied line voltage and create an over voltage condition during turn off� Likewise, verify that the inrush currents associated with mechanical loads having high starting torque or inertia, such as fans and flywheels, are within the surge capabilities of the SSR� Use a current shunt and oscilloscope to examine the duration of the inrush current� 28 ## _Application Data (continued)_ ## **Magnecraft[®] Solid State Relays** ## **Transformers** In controlling transformers, consider the characteristics of the secondary load because they reflect the effective load on the SSR� Voltage transients from secondary loads circuits, similarly, are frequently transformers and can be imposed on the SSR� Transformers present a special challenge in that, depending on the state of the transformer flux at the time of turn off, the transformer may saturate during the first half-cycle of subsequently applied voltage� This saturation can impose a very large current (10 to 100 times rated typical) on the SSR which far exceeds its half cycle surge rating� SSRs having random turn on may have a better chance of survival than a zero cross turn on device for they commonly require the transformer to support only a portion of the first half cycle of the voltage� On the other hand, a random turn on device will frequently close at the zero cross point and then the SSR must sustain the worst case saturation current� A zero cross turn on device has the advantage that it turns on in a known mode and will immediately demonstrate the worst case condition� The use of a current shunt and an oscilloscope is recommended to verify that the half cycle surge capability is not exceeded� A rule of thumb in applying an SSR to a transformer load is to select an SSR having a half cycle current surge rating greater than the maximum applied line voltage divided by the transformer primary resistance� The primary resistance is usually easily measured and can be relied on as a minimum impedance limiting the first half cycle of inrush current� The presence of some residual flux plus the saturated reactance of the primary will then further limit, in the worst case, the half cycle surge safely within the surge rating of the SSR� ## **Switching Devices** The power family of semiconductors consists of several switching devices� The most widely used of this family are metal-oxide semiconductor field effect transistors (MOSFETs), silicon controlled rectifiers (SCRs), Triac, and Alternistor Triac� In many applications these devices perform key functions and therefore it is imperative that one understand their advantages as well as their shortcomings to properly design a reliable system� Once applied correctly SSRs are an asset in meeting environmental, speed, and reliability specifications which their electromechanical counterparts could not fulfill� ## **• MOSFET** A power MOSFET is a specific type of metal oxide semiconductor field-effect transistor (MOSFET) designed to handle large amounts of power� It is a vertical structured transistor capable of sustaining high blocking voltage and high current� Power MOSFET’s are used in DC switching applications� Care must be taken to ensure that there is proper polarity for all DC ports� Failure to do so can lead to permanent device damage� ## **• Triac** A TRIAC, is an electronic component approximately equivalent to two silicon-controlled rectifiers joined in inverse parallel (paralleled but with the polarity reversed) and with their gates connected together� This results in a bidirectional electronic switch which can conduct AC current only� The Triac is ideal for switching non-reactive loads� ## **• Alternistor Triac** The Alternistor has been specifically designed for applications that switch highly inductive AC loads� A special chip offers similar performance as two SCRs wired inverse parallel (back-to-back), providing better turn-off behavior than a standard Triac� The Alternistor Triac is an economical solution; ideal for switching inductive AC loads� ## **• SCR** The SCR (silicon-controlled rectifier) acts as a switch, conducting when its gate receives a current pulse, and continue to conduct for as long as it is forward biased� The SCR is ideal for switching all types of AC loads� 29 _Selection Guide_ ##
