Power Supply | Convection Cooled | 250W | GWS250

Supplier: Helios Power Solutions Pty Ltd

Amtex Electronics recently introduced a new line of "green" 250-watt convection cooled power supplies that comply with the European energy saving requirements of the ErP (Energy related Products) Directive.

Price Guide: POA

Ideal 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 (<0.5W, no-load).

The GWS250 is equally well-suited for indoor as well as outdoor applications, including: LED information displays, digital signage, traffic controls, test and measurement and audio/visual systems.

Designed with a 104 x 198mm footprint and less than 1U height (41), the GWS250 is a com-pact, convection-cooled power supply that fits into spaces previously requiring fan-cooled supplies.

Rated at 250W, this series is offered in four models with nominal outputs of 12V, 24V, 36V 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 300W.

With a very flat efficiency curve averaging 92.7% from 25 to 100% load, the GWS250 series can be operated at full load from -25 to +50°C ambient temperature and up to +70°C with suitable derating.

Since the GWS250 is convection-cooled and does not have a fan, thus 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 GWS250 series includes overvoltage, over temperature and over current protections. Models also feature <0.5W no-load power consumption, 5V/0.3A standby output, remote on/off, DC GOOD signal and a programmable output function, as standard.
