Power specialist XP Power has launched what the company believes to be the world”s smallest 5 & 10 Watt single output AC-DC power supplies. Measuring just 25.4 x 25.4 x 15.24 mm (1 x 1 x 0.6 inches) the 5 Watt ECE05 series of encapsulated board mount power supplies have been designed for use in end-product designs where the available board space is at a premium and a low power high power density supply is required.
Complementing the ECE05 series, the ECE10 series provides 10 Watt output from an equally compact encapsulated package measuring just 38.1 x 25.4 x 15.24 mm (1.5 x 1 x 0.6 inches).
Both series comprise seven models covering the popular nominal output voltages from + 3.3 to + 48 VDC, all from a wide universal input of 85-264 VAC with Class II construction, meaning no earth or ground connection is required. All models meet the internationally recognized no-load power consumption limit of less than 0.3 Watt and average efficiency limits ensuring end-products can comply with world-wide energy efficiency standards.
A peak load capability permits an output of up to 130 % of nominal output power to cater for short-term high power loads without the need to specify a higher rated power module, saving both board space and additional cost.
The ECE05/10 modules are convection cooled and operate without the need for additional heat sinking or forced airflow. Operating temperature is across the range of – 25 to + 70 degrees C, with no derating until + 50 degrees C.
The units meet international IT safety standards EN60950-1, UL609501-1 and CSA22.2 No. 234. They also comply with EN55022 level B limits for conducted and radiated EMC without the need for any additional filtering components.
