HRP-450-12 Description

Short technical summary and product information.

The Mean Well USA HRP-450-12 is a 450W AC/DC converter providing a regulated 12V output at up to 37.5A. It accepts a universal AC input of 85 to 264 VAC or120 to370 VDC and operates at a typical efficiency of 88% at full load. Active power factor correction achieves PF greater than0.95 at230 VAC and0.99 at115 VAC. The unit includes a DC OK signal and comprehensive protections including overload, over voltage, and short circuit. Withstand voltage ratings are3 kVAC input to output,2 kVAC input to ground, and0.5 kVAC output to ground. Operating temperature ranges from -40 to70°C with derating; storage temperature -40 to85°C. MTBF is1,323.6K hours per Telcordia SR-332 and139.9K hours per MIL-HDBK-217F (25°C). Ripple and noise are limited to120 mVp-p maximum.
