Cooling is by a built-in temperature-controlled DC fan; the unit is 1U low-profile (325×107×41mm) with up to 37W/in³ density. Advanced functions include output voltage / constant-current programming, remote ON/OFF, remote sense, auxiliary power, DC-OK / alarm, PMBus (CANBus optional), built-in OR-ing FETs for hot-swap, and active current sharing—up to 12800W in one 19" rack shelf (DHP-1UT) and 25600W in 7+1 system. Protection covers SCP, OLP (105–115% → constant-current, shutdown after 5s), OVP (63–75V), and OTP. With -30°C ~ +70°C operation and a 5-year warranty, DRP-3200-48 is built for redundant rack power, not basic enclosed use.
3216W / 48V 67A: High-density 48V rail for telecom, automation, charging, test benches, 48V DC bus.
Universal Input + 94.5% Efficiency: 90–264V AC / 127–370V DC, PF 0.97, best-in-class 48V efficiency.
Digital / Communicable: PMBus standard, CANBus optional; programmable Vout + constant-current level; remote ON/OFF, sense, aux, DC-OK, alarm.
Hot-Swap Rack Platform: Built-in OR-ing FETs, active current sharing, DHP-1UT shelf → 12800W, 7+1 system → 25600W.
Redundant-Grade Reliability: SCP / OLP / OVP / OTP, -30°C ~ +70°C, 1U 325×107×41mm, UL/TÜV/EN 62368-1, 5-year warranty.
