The CUS250LD power supplies operate from a universal input of 85-264Vac, 47-63Hz, with PFC, enabling them to be used anywhere in the world. Typical applications include those in light industrial, LED signage, communications, broadcast, point-of-sale, IT, and test & measurement equipment. Operating from a 120-370Vdc input, these units have an input-to-output withstand voltage of 3kVac. The CUS250LD series is available with nominal output voltages of 3.3V, 4.2V, 5V, 12V, or 24Vdc. All of these voltage options have a ±10% user adjustment range.
Featuring power-saving efficiency up to 90%, the convection cooled operating temperature range is from -25°C to +70°C with derating above +40°C. Other standard features include overvoltage and overcurrent protection plus a green LED indicator that is lit when the supply is on.
The CUS250LD series features global ITE and general purpose safety agency certifications according to UL/CSA/EN60950-1. CE marked in accordance with the LV Directive and RoHS Directive, the power supplies conform to EN55022-B and FCC Class B for conducted and radiated EMI and include a three-year warranty.
