MEAN WELL HRP-75-36 is an enclosed single-output AC/DC switching power supply with active PFC, rated for 36VDC at 2.1A and 75.6W output power. The HRP-75 platform uses free-air convection, remote ON/OFF control, and a low-profile 38mm enclosure. Confirm output loading, wiring, final enclosure cooling, derating, and finished-system safety before integration.Technical details below were checked against the MEAN WELL English series datasheet. Confirm final wiring, protection coordination, enclosure design, cooling, and derating against the datasheet before system integration.Features 36V regulated output - Rated for 36VDC at 2.1A, with 75.6W output power. Universal AC/DC input - Accepts 85-264VAC or 120-370VDC input at 47-63Hz according to the English datasheet. Active PFC - The datasheet lists PF above 0.9 at 230VAC and above 0.95 at 115VAC under full load. 300VAC surge tolerance - The HRP-75 series is specified to withstand 300VAC surge input for 5 seconds. Free-air cooling - Uses free-air convection in a low-profile 38mm enclosure; validate final enclosure airflow and derating. Remote ON/OFF - Remote control uses RC+/RC-; 0-0.8VDC is power on and 4-10VDC is power off. Protection functions - Includes short-circuit, overload, and over-voltage protection; over-temperature protection is optional. Warranty - MEAN WELL lists a 5-year warranty for this series.
