GWS250 250 W Power Supplies

A line of green 250 W power supplies that comply with the European energy saving requirements of the ErP (Energy-related Products) Directive are for use in industrial, broadcast, and communications applications. The GWS250 series AC-DC power supplies employ innovative design techniques to combine high efficiency, high power density, and low standby power consumption (<0.5 W, no-load) with the confidence of a 5-year warranty. The GWS250 is equally well-suited for indoor as well as outdoor applications, including LED information displays, digital signage, traffic controls, test & measurement, and audio/visual systems.

Designed with a 4 x 8 in. (102 x 203 mm) footprint and less than 1U height (2 in. (51 mm)), the GWS250 is a compact, convection-cooled power supply that fits into spaces previously requiring fan-cooled supplies. Rated at 250 W, this series is offered in 4 models with nominal outputs of 12, 24, 36, and 48V. Outputs are user-adjustable by up to 20% depending on the model and the 24V and 36V models have a peak power rating of 300 W.

With a very flat efficiency curve averaging 92.7% from 25 to 100% load, the GWS250 series can be operated at full load from -13 to 122°F (-25 to 50°C) ambient temperature and up to 158°F (70°C) with suitable derating. Since the GWS250 is convection-cooled and does not have a fan, it is ideal for applications requiring low audible noise as well as for equipment where long life is a critical factor, such as in remote locations and dusty environments.

The series includes overvoltage, overtemperature, and overcurrent protections. Models also feature <0.5 W no-load power consumption, 5V/0.3 A standby output, remote on/off, DC GOOD signal, and a programmable output function. CE marked in accordance with the LV Directive, the GWS250 carries environmental and safety approvals including EN55022 and FCC Class B, UL60950-1, CSA C22.2 No.60950-1-07 (cUL), EN60950-1 edition 2 and IEC60950-1.
