DESCRIPTION
The PSAK450 series of AC/DC switching power supplies provides up to 457 Watts of output power
in a 7.835” x 4.134” x 1.614” enclosed case. This series consists of single output models ranging
from 12VDC to 48VDC with an input voltage range of 90~264VAC (127~370VDC). Standard
features include high efficiency up to 93%, active PFC, remote on/off, remote sense, and power
OK signal. This series also has short circuit, over load, over voltage, and over temperature
protection. All models are RoHS compliant and have UL 60950-1 and EN60950-1 safety approvals.

NOTES
1. Ripple & noise is measured at 20MHz limited bandwidth and using a 12" twisted pair-wire terminated with a 0.1µF & 47µF capacitors in parallel.
2. For voltages near the low end of the input voltage range, see the derating curve for the power supply output rating.
3. The power supply is considered a component which will be installed into final equipment. The final equipment must be re-confirmed that it still
meets EMC directives.
