Encapsulated 60W off-line PSU is industry's smallest, claims XP

September 18, 2014 // By Graham Prophet
Extending a product series that it began with 5 and 10W sealed, encapsulated, AC-DC power supply modules, XP's ECE60 series of single output 60W AC-DC units match applications that require a slim profile, a high power density and low no-load power consumption.

The units come in PCB mount, with wire/pin terminations, or chassis mounted with screw terminals, or by addition of a standard bracket, in a DIN rail mount configuration. In the DIN format, you get a low=profile, as opposed to minimal-rail-length, installtion. Believed to have the smallest footprint and the highest power density of any 60W supply, the PCB mounted model measures 91.4 x 38.1 x 28.0 mmand has a power density of over 10W per cubic inch.

The range comprises eight models providing all the popular nominal output voltages from + 3.3 to + 48 VDC. A peak load capability allows up to 130% of rated output power to be available for up to 30 seconds in order to accommodate a higher start up current. Using this approach allows an engineer to avoid having to specify a more expensive higher rated power supply just to provide for an occasional peak load requirement. No load power consumption is less than 0.3W and efficiency is up to 89%.

The ECE60 meets EMC specification EN55022 for class B conducted and radiated emissions without the need for any additional filtering components. The supply is able to operate in most environments over -25 to + 70C with no derating until + 50 degrees C. With a Class II construction no earth/ground connection is required.
