TDK-Lambda UK has developed a series of power supplies that comply with the energy saving requirements of Energy Star and the ErP (Energy related Products) Directive.

Designed for use in light industrial equipment and front-end equipment for broadcast and communications applications, the 250W GWS series AC-DC power supply has a 105x198mm footprint and 1U height.

Convection cooled and rated at 250W, the power supply is offered in four models with nominal outputs of 12V (21A), 24V (10.5A), 36V (7A) and 48V (5.3A).

Outputs are user adjusted by up to 20% depending on model type – and the 24V and 36V models have a peak power rating of 300W.

With a flat efficiency curve averaging at 93%, from 25 to 100% load, the supplies can be operated at full load from -25 to 50°C ambient temperature and up to +70°C with suitable de-rating.

The supplies have overvoltage, over-temperature and over-current protection (constant current mode for 24V, 36V and 48V models, 12V hiccup mode). Models also feature less than 0.5W no-load input power, 5V/0.3A standby output, remote on/off, DC GOOD signal and a voltage programming function as standard.
