Datasheet

ECF40 series 

## 40W **Convectioncooled** 

**AC-DC power supplies** 

The ECF40 series is designed to minimize the no load power consumption and maximize efficiency to facilitate equipment design to meet the latest environmental legislation. Approved for medical (2 x MOPP) and ITE applications in either Class I or Class II installations and has two AC line fuses and low leakage currents required by medical applications. 

This range of single output AC-DC power supplies are packaged in a low profile 28.0mm height with a foot print of just 76.2 x 38.1mm. The ECF40 provides up to 40W convection-cooled over the full 90-264VAC input range, and operates down to 80VAC with minimal de-rating. The low profile, low noise and safety approvals covering ITE and medical standards allows the versatile series to be used in a wide range of applications.

Thermal considerations 

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 thermocouples placed on the hottest part of the component (out of direct air flow). See mechanical details for component locations. 

|Temperature measurements (at maximum ambient)|Temperature measurements (at maximum ambient)|
|---|---|
|Component|Max temperature (°C)|
|TR1 coil|120°C|
|L1 coil|120°C|
|C2|105°C|
|C13|105°C|
|C14|105°C|

## **Application notes** 

## Service life 

The estimated service life of the ECF40 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 key capacitors with in the product when installed by the end application. The graph below expresses the estimated lifetime based on the temperature of these key components based on the average temperature over the lifetime of the equipment.
