Published:2012/2/3 2:30:00 Author:Amy From:SeekIC

TDK-Lambda Americas has announced a new line of “green” 500-watt power supplies, which is very suited for use in industrial, broadcast, and communications applications, the GWS500 series power supplies employ innovative design techniques to combine high efficiency, high power density and low standby power consumption (<0.5W, no-load) with the confidence of a 5-year warranty.

It is a 500W ac-dc, forced air-cooled power supply and the efficiency can be as high as 90%, dramatically cutting the heat generated in industrial, LED, display/signage, IT, traffic controls, automated service, kiosks, test & measurement, and audio/video applications.

With a 4.1 x 8.6 inch footprint and 1.6 inch height, the GWS500 is claimed to be the minimum product in its class and well suited for fitting into 1U enclosures. Rated at 500W, this series is provided in six models with nominal outputs of 5V, 7.5V, 12V, 24V, 36V and 48V. In addition, the GWS500’s output is adjustable. Where peak power is needed, the 24V and 36V models can deliver up to 600W for 10 seconds. The supply can be operated at full load from -25 to +50°C ambient temperature and up to +70°C with suitable derating.

These power supplies include overvoltage, overtemperature and overcurrent protections. Also 5V/0.3A standby output, remote on/off, and DC Good signal are included.

The GWS500 has UL/EN/IEC 60950-1 safety approval (2nd Edition). All models meet EN61000-4-X immunity and EN61000-3-2 harmonic correction standards. These units are available now and economically priced, starting at $200.00 each in 250 piece quantities.
