250-W power supplies combine 93 percent efficiency and ErP compliance with 0.5-W no load input power
The GWS250 is equally well-suited for indoor and outdoor LED information displays and digital signage, traffic controls, test and measurement and entertainment systems.
Designed with a 105 x 199 mm footprint and 1U height, the GWS250 is a compact and convection cooled product fitting into spaces previously requiring a fan cooled model. Rated at 250W the power supply is offered in four models with nominal outputs of 12 V (21 A), 24 V (10.5 A), 36 V (7 A) and 48 V (5.3 A). Outputs are user adjusted by up to 20% depending on model type – and the 24 V and 36 V models have a peak power rating of 300 W. With a flat efficiency curve averaging at 93%, from 25 to 100% load, the GWS250 range can be operated at full load from -25 to 50°C ambient temperature and up to +70°C with suitable derating.
The GWS250 series from TDK-Lambda has overvoltage, overtemperature and overcurrent protection (constant current mode for 24 V, 36 V and 48 V models, 12 V hiccup mode). Models in the GWS250 series also feature <0.5 W no load input power, 5 V/0.3 A standby output, remote on/off, DC GOOD signal and a voltage programming function as standard.
CE marked in accordance with the LV Directive, the GWS250 carries a host of 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.
