DESCRIPTION
The PSHF320W series of AC/DC power supplies offers up to 322W of output power in a 8.46” x 4.53” x 1.97”
enclosed case. This series consists of single output models with a universal input voltage range of 85~264VAC
(120~370VDC). Some features include built-in fan speed control, power factor > 0.98 at 115VAC, and ±10%
output adjustment range. These supplies are also protected against short circuit, over current, over voltage, and
over temperature conditions. This series is RoHS compliant and has UL60950, EN60950, GB4943, and CE
approvals.
