The Bel Fuse/Power-One HA15-0.9-AG is a linear DC power supply engineered for industrial control systems, laboratory instrumentation, and enterprise electronics requiring stable, regulated power. This open-frame unit delivers 12V or 15V DC at 0.9 A (10.8–13.5 W) with exceptional output regulation of ±0.05% and low ripple performance. It accepts worldwide AC input from 100–240 VAC at 47–63 Hz and incorporates user-adjustable overvoltage protection (6.4–34 V range). Every unit undergoes 100% burn-in testing and achieves MTBF exceeding 300,000 hours.
