The ECP180 series has been designed to minimise no load power consumption and maximise efficiency facilitating equipment design
to meet the latest environmental legislation and minimising power loss and heating within equipment enclosures.
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 2.0” by 4.0”.
The ECP180 provides up to 180W force-cooled or 120W convection-cooled leading to very high power densities of 22W/in3or
15W/in3respectively. A 12V, 500mA fan supply is 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 meeting EN55011/22
level B allow the versatile ECP180 series to be used in a vast 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 K type thermocouples placed on the hottest part of the component (out of direct air flow). See
Mechanical Details for component locations.
Service Life
The estimated service life of the ECP180 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.
