250-W convection cooled power supply eliminates fan maintenance and audible noise
In addition, they feature a low profile of 30 mm and a compact footprint of 198 x 101.6 mm, making them an ideal choice for applications in light industrial, LED signage, communications, broadcast, point-of-sale, IT, and test & measurement equipment.
The supplies operate from a universal input of 85-264 Vac, 47-63 Hz, with PFC, enabling them to be used anywhere in the world. Moreover, they can operate from a 120-370 Vdc input. These units have an input-to-output withstand voltage of 3 kVac. The CUS250LD series is available with nominal output voltages of 3.3 V, 4.2 V, 5 V, 12 V, or 24 Vdc, all of which have a ±10% user adjustment range.
The convection cooled operating temperature range is from -25°C to +70°C with derating above +40°C. The power-saving efficiency is up to 90%. 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.
