Green 500W Power Supplies Introduced by TDK-Lambda
Combines 90% efficiency with ErP compliance
San Diego, CA – February 2012– TDK-Lambda Americas, a group company of the TDK Corporation, 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.
Ideal 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.
This is a 500W ac-dc, forced air-cooled power supply that achieves up to 90% efficiency, dramatically cutting the heat generated in industrial,
LED, display/signage, IT, traffic controls, automated service, kiosks, test & measurement, and audio/video applications.
Featuring a 4.1 x 8.6 inch footprint and 1.6 inch height, the GWS500 is the smallest product in its class and well suited for fitting into 1U
enclosures. Rated at 500W, this series is 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 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 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.
These units are available now and economically priced, starting at $200.00 each in 250 piece quantities. More information is available at

Meeting Future ErP Requirements Today
Within the EU (European Union) in November 2009 the EuP (Eco-design Directive for Energy-using Products) was replaced by the new ErP
(Energy-related Products Directive, 2009/125/EC). One of the first measures implemented under the ErP Directive relates to the no-load power
consumption. Initially, this has been set at less than 1W. However, it is expected to drop to below 0.5W by January 2013. With this in mind,
TDK-Lambda designed the GWS series with less than 0.5W no-load standby power, helping designers achieve existing regulations now and ensuring
that end systems are future-proofed beyond January 2013.
