The Power One PFC375-S132 is a 375 W continuous AC-to-DC power supply designed for industrial and commercial electronics requiring active Power Factor Correction. It operates from 85–265 VAC across 47–63 Hz with a power factor of 0.98 per EN61000-3-2 and delivers peak output of 450 W for up to 60 seconds at 10% duty cycle maximum. The unit features overtemperature, overvoltage, and overcurrent protection with 20 mS hold-up time across the full AC input range.

– Compatibility & Integration
Remote sense capability corrects for cable voltage drops across distributed loads. TTL-compatible control signals integrate with standard logic circuits. Parallel operation supports up to 6 units with 10% current-sharing accuracy for N+1 or load-sharing redundancy. Multiple output models require minimum loads of 3.5 A (5V) or 1 A (24V); single-output configurations accept 0 A minimum.
