## Input Current vs Input Voltage Graphs (For Power Supply Selection) 

To ensure the Solid-State Relay (SSR) operates efficiently and reliably, it is essential to understand the relationship between input voltage and input current. The following input current graphs provide detailed information on the current consumption of our SSRs across the specified input voltage range (4-32 VDC). This data is crucial for selecting an appropriate power supply and ensuring the relay functions within its safe operating limits. Proper understanding of current consumption is vital for the optimal performance of your application.

## Considerations – Switching Type 

DC output SSRs are versatile and can be used to control various types of loads, including resistive loads such as heating elements, and inductive loads like DC motors and valves. This flexibility makes them suitable for a wide range of industrial and commercial applications.

## Considerations – Inrush Current 

When dealing with DC loads, it’s important to consider the inrush current, especially for inductive loads such as motors and valves: 

• DC motors and valves can generate inrush currents that are 3-4 times their steady-state current. To accommodate this, it is recommended to select an SSR with a current rating 3-4 times the nominal current of the load, or to operate the SSR at 25%-35% of its maximum capacity to help manage these high currents and protect the relay and other components. 

• For DC resistive loads, inrush current is generally less of a concern compared to inductive loads. However, it’s still prudent to account for any potential surges, especially if the load includes capacitive elements. Ensuring the SSR operates within 80%-90% of its maximum capacity can enhance reliability and lifespan. 

|NOMINAL SSR CURRENT RATING|MAXIMUM RECOMMENDED CURRENT<br>RESISTIVE LOADS|MAXIMUM RECOMMENDED CURRENT<br>INDUCTIVE LOADS|
|---|---|---|
|20 A|16-18 A|6-10 A|
|40 A|32-36 A|12-20 A|



## Output Surge Current Withstand Graphs (For Transient Protection) 

To ensure the Solid-State Relay (SSR) can handle sudden increases in current without damage, it is essential to understand its surge current capacity. The following surge current graphs illustrate the maximum surge current that our SSRs can withstand over various durations. This information is crucial for selecting an SSR that can endure transient overcurrent events, ensuring the reliability and safety of your electrical system. Proper understanding of surge current capacity helps in preventing equipment failure and maintaining optimal performance in your application. 

The graphs include a Single Pulse Surge Current curve used to define the protection offered by fuses, helping in the selection of appropriate protective devices. Additionally, is important to ensure that the Repetitive Surge Current curve is not exceeded during normal operation, as frequent overload currents can decrease the life expectancy of the SSR. Therefore, caution is advised to maintain the longevity and reliability of the SSR.

## **Short-Circuit Protection by Fuse** 

To safeguard solid-state relays (SSRs) against load short circuits, the use of fuses is essential, especially fast-acting ones. Here are the key considerations: 

- Fuse Selection: The I²t value (energy withstand capability) of the fuse should be less than half of the I²t value of the relay. Standard fuses are inadequate because they cannot react swiftly enough to prevent fault currents from exceeding the maximum levels that thyristors (used in SSRs) can handle. Therefore, we strongly recommend employing ultra-fast fuses. 

- Fuse Placement: Position the fuse in front of the SSR in the circuit. This strategic placement ensures that if the relay must unexpectedly break the earth insulation (due to overheating, case damage, or leakage with the heatsink), the fuse will protect the entire circuit from firing. 

- Resource for Fuse Options: For the most suitable fuse options, consider checking the Littelfuse website.

## **EMC Compliance (Electro-Magnetic Compatibility)** 

## Radiated Emissions 

|-|STANDARD NAME|STANDARD DESCRIPTION|STANDARD NUMBER|LEVELS|
|---|---|---|---|---|
||Radiated RF|Radio interference field emission<br>(radiated)|International Standard CISPR 11|Class A: 30M – 1GHz|
||Conducted RF|Radio interference voltage<br>emissions (conducted)|International Standard CISPR 11|Class A (with external filter):<br>150k – 30MHz|



## Immunity 

|Immunity|||||
|---|---|---|---|---|
|-|STANDARD NAME<br>ESD|STANDARD DESCRIPTION<br>Immunity to Electrostatic Discharge<br>(ESD)|STANDARD NUMBER<br>International Standard IEC<br>61000-4-2|LEVELS<br>Level 3:<br>-Contact Discharge: ± 6 kV<br>-Air Discharge: ± 8 kV<br>-Performance Criteria: A|

While these products are designed to meet high industrial standards for Class A equipment, ensuring robust performance in demanding environments, they may cause radio interference when used in domestic settings. To mitigate this, additional noise reduction measures, such as filters or shielding, may be necessary. Ensure that the entire setup where the SSR is installed complies with all relevant EMC regulations required by the application. 

## **Environmental Compliance[2]** 

Products comply to the following environmental standard requirements for electrical products to ensure they are safe for consumers to use.
