280 Watt Medical Power Supplies

Product Information

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

RD-280P series 280 watt Medical Power Supplies have Universal AC Input from 90-264VAC with outputs of 12V, 24V, 28V, 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.  210W is available with free air convection.

RD-280P series 280 watt Medical Power Supplies have approvals to the UL60601-1 3rd Edition, CSA22.2 No.60601-1 3rd Edition and EN60601-1 3rd Edition standard, offer Class B line emissions and will operate over a wide 0°C to +70°C ambient temperature range.

THREE YEAR WARRANTY
