The PSHF35W series of AC/DC switching power supplies offers up to 36 Watts of output power in a

3.88” x 3.23” x 1.38” enclosed case. This series consists of single output models ranging from 5VDC to

48VDC with a 170~264VAC (210~370VDC) input voltage range. Some features include ±10% output

adjustability, high efficiency up to 85%, and over load and short circuit protection. The PSHF35W series

has GB4943, UL60950, and EN60950 safety approvals and meets GB9254 and EN55022 Class A EMC

standards. These supplies are also RoHS compliant and have been 100% full load burn-in tested.

TECHNICAL SPECIFICATIONS: PSHF35W SERIES

All specifications are based on 25°C, Nominal Input Voltage, and Maximum Output Current unless otherwise noted.

We reserve the right to change specifications based on technological advances.
