Technical content

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 and is safety approved to operate in a 70°C ambient. 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.

  • 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 95% w w w .xppow er.com 1 Notes 1. Typical efficiencies m easured at 100% load and 230 VAC input. 2. Typical voltage, actual regulated voltage w ill be in range of 11.4V to 12.6V. 3. Regulation of the fan output requires a m inim um load of 10W on the m ain output. 4. Add suffix -C to part num ber for vented cover version, -TF for top fan version and -EF for end fan version. ECH 450 Series AC -D C Pow er Supplies
