500W power supply combines 1U form factor with 105x218mm footprint and 90% efficiency
The GWS500 is well-suited to a broad range of industrial applications, including ATE, automation and instrumentation. Rated at 500W, the GWS500 combines a 1U form factor with 105x218mm footprint and 90% typical efficiency to achieve a power density of 8.7W/in3. Offered in 4 models, the GWS500 supplies nominal outputs of 12V (42A), 24V (21A), 36V (14A) and 48V (10.5A). Outputs can be user-adjusted by up to 20% depending on the model type, and the 24V and 36V models have a peak power rating of 600W. With a flat efficiency curve averaging at 89%, from 25 to 100% load, which exceeds the ErP requirement of 87%, the GWS500 operates from -25 to 70°C with suitable derating. The high power GWS500 is reverse fan cooled (exhale) to mitigate contamination risk.
The unit has overvoltage, overtemperature and overcurrent protection (constant current mode for 24V, 36V and 48V models, 12V model in hiccup mode). Models in the GWS500 series also feature a sub-0.5W standby power, 5V/0.3A standby output, remote on/off, DC GOOD signal and a voltage programming function as standard.
All GWS500 models operate from an 85-264Vac input with active power factor correction to ensure EN61000-3-2 compliance. CE marked in accordance with the LV Directive, the GWS500 conforms to EN55022 and CISPR22 Class B conducted and radiated EMC, and meets CSA/IEC60950-1 Ed 2 and UL/EN60950-1 safety approvals.
