SAN DIEGO, 6 Feb. 2012. TDK-Lambda Americas of the TDK Corp. has introduced a new line of green, 500-watt power supplies that comply with the European energy-saving requirements of the ErP (Energy-related Products) Directive. The GWS500 series power supplies are designed to combine high efficiency, high power density, and low standby power consumption (<0.5W, no-load).

The 500-watt AC-DC, forced air-cooled power supply that achieves up to 90 percent efficiency, cutting the heat generated in LED, IT, test and measurement, and audio/video applications.

Featuring a 4.1 x 8.6-inch footprint and 1.6-inch height, the GWS500 is well suited for fitting into 1U enclosures and offered in six models with nominal outputs of 5V, 7.5V, 12V, 24V, 36V, and 48V. To accommodate non-standard system voltages, the GWS500’s output is user-adjustable, either via the built-in adjustment potentiometer or by injecting an external programming voltage. Where peak power is needed, for example for motor start-up, the 24V and 36V models can deliver up to 600 watts 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 included are 5V/0.3A standby output, remote on/off, and DC Good signal, as standard.

The GWS500 is UL/EN/IEC 60950-1 safety certified (2nd Edition) and carry the CE mark. All models meet EN61000-4-X immunity and EN61000-3-2 harmonic correction standards.
