High-Efficiency Power Supply

June 28, 2017
Power Sources Unlimited, Inc. offers an open-frame ac-dc power supply

Cincon CFM300S Series open-frame industrial ac-dc power supply provides 300W of regulated power in a 3 in. x 5 in. footprint.


Measuring 3.00 x 5.00 x 1.26 in. (76.20 x 127.00 x 32.00 mm) with a high-density up to 18W/in.3, the CFM300S series has a wide universal input voltage range of 90~264VAC and is available in single output voltages of 12, 24, 36, and 48VDC. All models feature a 5V Stand-By output and 12V fan output with high efficiency up to 94% at 230VAC and provide ambient operating temperature range of –40° to 80°C (derating above 40°C). The modules are fully protected against output over-current, output over-voltage and over-temperature and continuous short circuit conditions. CFM300S series also offers a very low no load power consumption (<0.3W) and extremely low leakage current (?300µA). Standard control functions include PS On/Off, remote control and ±5% adjustable output voltage.
