Single-Phase AC DIN Rail Power Supply 480W

The DPS-480 is a high-reliability, single-phase AC input DIN rail power supply delivering 480 W at 24 VDC or 48 VDC in an extremely compact 52 mm wide enclosure, compliant with IEC/EN/UL 61010-1, IEC/EN/UL/CSA 61010-2-201, and heavy industrial EMC standards IEC/EN 61000-6-3 Class B and IEC/EN 61000-6-2. Specially designed for demanding industrial automation applications, it features Active Power Factor Correction (PFC 0.95) and active inrush current limitation, with extended return voltage immunity for safe operation with back-feeding loads such as decelerating motors and inductors.

The DPS-480 accepts a wide single-phase input range of 85–277 VAC (47–63 Hz) and DC input from 88 to 370 VDC, and is available in two output versions: 24 VDC (adjustable 24–28 V, 20 A) and 48 VDC (adjustable 48–56 V, 10 A), both with a maximum rated output power of 480 W. It delivers full power over the -40 °C to +60 °C ambient temperature range with natural convection only. A Thermal Power Bonus of up to 576 W at 45 °C and a 150% power boost for 5 s make it ideal for highly inductive or capacitive loads, with an efficiency of up to 95.4% and a lifetime expectancy of 122,000 h at 40 °C / 75% load.

The DPS-480 features an innovative slim design with 25° angled push-in connectors for fast, tool-less installation and replacement on standard TS35 DIN rail (EN 60715). Selectable Constant Current (CC) or Parallel Load Share mode via DIP-switch, a DC-OK signal contact, load indication LED, adjustable output voltage via on-board potentiometer, and support for redundant 1+1 or parallel 1+n operation with the RDM-40 redundancy module make the DPS-480 a complete solution for critical industrial DC distribution systems.
