DESCRIPTION
The PSPDF‐480 series of AC/DC switching power supplies provides up to 528 Watts of output
power in a 8.58” x 4.59” x 1.61” enclosed case with built‐in fan. This series consists of single
output models ranging from 12VDC to 48VDC with an input voltage range of 90~264VAC.
Standard features include high efficiency up to 90%, 3000VAC I/O isolation, and a ‐30°C to +70°C
operating temperature range. This series also has short circuit, over load, over voltage, and over
temperature protection. All models are RoHS compliant and have UL60950‐1 (2nd edition),
IEC60950‐1:2005 (2nd edition), and EN60950‐1:2006 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. 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.
