250/450W power supplies are compact for healthcare, industrial and ITE
Compact, high efficiency power supplies in the ECH450 series are available from XP Power in open frame or a range of enclosed formats.
They deliver 250W when convection cooled and 450W when force cooled, or when using the enclosed versions with an integral fan. They offer class B conducted and radiated emissions and carry worldwide information technology equipment (ITE) and medical approvals making the models suitable for a range of industrial, IT and healthcare applications including those requiring body floating (BF) patient protection.
The convection cooled ratings make the power supplies suitable for medical device applications, where audible noise is undesirable, and industrial or ITE applications where fanless operation increases reliability and minimises dust ingress.
Efficiency levels are up to 94 per cent and the ECH450 power supplies minimise waste heat and reduce operational costs, says XP. They operate at full rated power at ambient temperatures up to +50 degrees C without derating and at half power at +70ºC ambient. Peak load applications are supported up to 450W with convection cooling with average power up to 250W.
ECH450 units start at a compact 5.0 x 3.0 inch (127 x 76 mm) footprint with a low 1.4 inch (35 mm) profile. They have a universal input range for worldwide use. Single output voltages available are 12.0, 15.0, 19.0, 24.0, 36.0, 48.0 and 54.0V.
Mechanical configurations include fanless units that are open frame or fitted with an optional vented cover (-C). Units with an integral fan have the option of either an end fan (-EF) or a top fan (-TF) to suit the airflow requirements of the end equipment. The choice of formats ensure easy mechanical integration, says XP. The open frame and vented cover (-C) units include a 12V, 600mA fan supply to power a remotely located cooling fan and all versions come with a 5V/1A standby supply.
Medical approvals to IEC60601-1 provide two means of patient protection (2 x MOPP) input to output isolation. There is also basic isolation from output to ground and low levels of leakage current, both of which ensure that ECH450 power supplies are suitable for BF applications.
As well as IEC, UL and EN60601-1 approvals for medical applications, the ECH450 is approved to IEC, UL and EN62368-1 for industrial and ITE applications. Compliance with Class C input current harmonics makes the ECH450 suitable for lighting and display applications.
The ECH450 power supplies meet EN55011/32 Level B conducted and radiated emissions with a significant margin allowing designers to integrate them easily and with minimal risk to system level EMC approval.
The ECH450 series is available from Digi-Key, Farnell, Mouser, RS Components, approved regional distributors, or direct from XP Power and offer a three-year warranty.
