In summary, the GWS250 series power supply is available in four output voltages; 12V, 24V, 36V and 48V, and can deliver up to 250W with convection cooling, no internal fan or forced air is required. Features include remote ON and OFF control using the CNT terminals, a normally low “DC OK” signal that will go high if the power supply output drops below 80% of nominal and a standby voltage output which is rated at 5V, 0.3A. The GWS250 meets class B radiated and conducted emissions for Europe and the USA and is certified to UL, CSA, EN 60950-1 and carries the CE mark. This power supply series can be used in equipment that needs to meet either Energy Star in the US or the European ErP/EuP requirements for standby power, as the unit is specified to draw less than 0.5W. The GWS250 has PFC, circuitry allowing it to meet the European standard IEC 61000-3-2, including the tougher Class C standard that applies to lighting equipment.
