280 Watt Medical Power Supplies

Product Information

RD-280P Series are Single Output 280 Watt Medical Power Supplies, available in an open PCB or U-Channel format.

RD-280P series 280 watt Medical Power Supplies have Universal AC Input from 90-264VAC with outputs of 12V, 24V, 28V, 36V, 48V and 54V.  They also include a 5V @ 0.5A standby supply and a 12V @ 0.3A fan supply, making them easier to integrate into OEM applications that require forced cooling.  Up to 210W is available with free air convection.

RD-280P series 280 watt Medical Power Supplies approvals to UL/c-UL/EN 60950-1, UL/c-UL/EN62368-1, UL/EN/60601-1 Ed. 3.1, CB IEC 60950-1 & CB IEC 62368-1 standards, offer Class B line emissions and will operate over a wide 0°C to +70°C ambient temperature range.

THREE YEAR WARRANTY
