## 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)

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.

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.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
