HTM

The HTM series of AC/DC power supplies provides 300 Watts of output power in a 7.15” x 4.00” x 2.92” desktop style package with no internal fan. This series consists of single output models ranging from 12VDC to 48VDC with a universal input voltage range of 100-240VAC and an IEC-320-C14 AC inlet. Some features include active PFC, fixed switching frequency, and low THD. These supplies are protected against over current, short circuit, and over temperature conditions. All models have been 100% burn-in tested.
