Cooling is by a built-in intelligent DC fan with temperature-based speed control. Advanced functions include programmable output voltage (40–125% of nominal), remote ON/OFF, remote sense (±0.5V line-drop compensation), 12V/0.8A auxiliary power, DC-OK signal, over-temp/fan-fail alarm, and CANBus monitoring/control. Protection covers short circuit, overload (105–115% → constant-current limit, shutdown after 5s, re-power to recover), over voltage (63–75V), and over temperature. With SEMI F47 reference design, 2G vibration rating, and a 5-year warranty, the NSP-1600-48 is a smart high-density 48V OEM power platform.
1608W / 48V 33.5A: High-density 48V rail for automation, laser, test/burn-in, broadcasting, and industrial constant-current loads.
Active PFC + Full-Range Input: 90–264V AC / 250–400V DC, PF 0.97, 92.5% efficiency.
