350W Switching Power Supply Is Compact

Compact size, 350W of output power, full safety approvals, hot-swap capability, active current share and N+1 redundancy are all benefits of the PF-350 switching power supply, which is designed for RAID, server, disk drive, tape drive and JBOD applications. Three standard models are offered with PFC universal ac input of 90-240 vac that meet the conducted EN55022 "B" specification. The active power-factor correction is 0.99 at full load operation and meets the requirements of EN60555-2. Outputs are 5V at 25A and 12V at 25A, 30A peak. Other standard features include line regulation of 0.5%, load regulation of ±1% to 10% to full load, 20-ms holdup time, 1% peak-to-peak ripple, and power-fail and power-good TTL logic signals. Overvoltage, overload, short circuit and thermal protection are also standard on each model.
