The ECP225-A 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 and ITE applications, this range of single output AC/DC power supplies are packaged in an
ultra-low profile 1” height with a foot print of just 3.0” by 5.0”. The ECP225-A provides up to 225 W
force-cooled or 150 W convection-cooled leading to very high power densities of 15 W/in3or 10
W/in3respectively. A 5 V, 2 A standby output and a 12 V, 500 mA fan supply are included in the
design. The power supply contains two fuses and low leakage currents as required by medical
applications and is safety approved to operate in a 70 °C ambient. The low profile and safety
approvals covering ITE and medical standards along with conducted emissions to EN55011/22 level
B allow the versatile ECP225-A series to be used in a vast range of applications.

Estimated Service Life vs Component Temperature
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 Mechanical Details for component locations.
The estimated service life of the ECP225-A 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.
