# OPEN FRAME AC - DC CONVERTERS **URL**: https://novapart.co/products/ECH450PS36/open-frame-ac-dc-converters **SKU**: ECH450PS36 **Manufacturer**: XP POWER / PARTNER STOCK **Category**: Power & Line Protection || Power Supplies || AC / DC Converters || AC / DC Open Frame Power Supplies **Price**: €243.2300 **Stock**: 10+ ## Specifications | Parameter | Value | |---|---| | Svhc | To Be Advised | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:4862986/) **ECH450 Series AC-DC Power Supplies** aa ~~:~~ EG] Power ## 450 Watts - •Force cooled and convection cooled ratings - •Medical and ITE approvals - •Compact 3.0” by 5.0” footprint - •Suitable for BF applications - •5 V standby and remote on/off - •12 V fan output - •-20 °C to +70 °C operation - High efficiency, up to 94% Approved for medical and ITE applications, this range of forced and convection cooled single output AC/DC power supplies are packaged in an ultra compact foot print of just 5.0” by 3.0”. The ECH450 provides up to 450W force cooled and 250W convection cooled leading to very high power densities of 20W/in[3] . A 12V, 600 mA fan supply is included in the design to faciliate system cooling, along with 5 V/1 A standby output. The power supply contains two fuses and low leakage currents as required by medical applications. The ECH450 series is designed to minimize the no load power consumption and maximize efficiency to facilitate equipment design to meet the latest environmental legislation and the low profile and safety approvals covering ITE and medical standards along with conducted emissions to EN55011/32 level B allow the versatile ECH450 series to be used in a vast range of applications. Dimensions: ECH450: 3.00 x 5.00 x 1.42” (76.2 x 127.0 x 36.1 mm) ECH450-TF, ECH450-C: 3.41 x 5.00 x 1.97” (86.6 x 127.0 x 50.0 mm) ECH450-EF: 3.15 x 5.83 x 1.60” (80.0 x 148.2 x 40.6 mm) ## Models & Ratings |Output

Typical efficiencies measured at 100% load and 230 VAC input._ _2. Typical voltage, actual regulated voltage will be in range of 11.4V to 12.6V._ _4. Add suffix -C to part number for vented cover version, -TF for top fan version and -EF for end fan version._ _3. Regulation of the fan output requires a minimum load of 10W on the main output._ |Characteristic

Weight: 1.29lbs (585g) approx. **www.xppower.com** 10 **ECH450 Series** **AC-DC Power Supplies** In order to ensure safe operation of the PSU in the end-use equipment, the temperature of the components listed in the table below must not be exceeded. Temperature should be monitored using K type thermocouples placed on the hottest part of the component (out of direct air flow). See Standard Open Frame Mechanical Details on page 5 for component locations. Temperature Measurements (At Maximum Ambient) Component Max Temperature °C T3 Coil 110°C L3 Coil 120°C Q3 Body 120°C C5 105°C C39 105°C ~~——————~~ Service Life The estimated service life of the ECH450 is determined by the cooling arrangements and load conditions experienced in the end application. Due to the uncertain nature of the end application this estimated service life is based on the actual measured temperature of a key capacitor with in the product when installed by the end application, The graph below expresses the estimated lifetime of a given component temperature and assumes continuous operation at this temperature. ## **Estimated Service Life vs Component Temperature** Figure 6 **==> picture [398 x 236] intentionally omitted <==** **----- Start of picture text -----**
