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.
