DESCRIPTION
The PSUP350 series of AC/DC switching power supplies offers 300W with free air convection and 350W with 10.5CFM
forced air. These supplies are housed in a low-profile 9.09 x 4.0 x 1.50 inch U-chassis frame. These supplies have a
90~264VAC (127~370VDC) input voltage range and provide single outputs ranging from 12VDC to 48VDC. Standard
features include active power-factor-correction, remote on/off, remote voltage sense, power OK signal, and comprehensive
over voltage, short circuit, over load, and over temp. protection. There are two different output connector options available
for this series (Type C and Type T). All models are RoHS compliant and have UL/cUL, TUV, CE, and CB approvals.

NOTES
1. Ripple & noise is measured at 20MHz bandwidth by using a 12" twisted pair-wire terminated with a 0.1µF capacitor and a
47µF capacitor in parallel.
2. Tolerance includes set up tolerance, line regulation, and load regulation.
3. Derating may be needed under low input voltages. Please check the derating curve for more details.
4. 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.
5. There are two mechanical options available (Type C or Type T). Please see mechanical drawings on pages 5 and 6 for
more details.
