Overview
The Allen-Bradley 1606-XL480E-3 is a compact, three-phase switched-mode power supply from Rockwell Automation’s Bulletin 1606-XL series. Rated at 480 watts with a 20-amp output current, this DIN rail–mounted module delivers stable 24–28V DC power to PLC modules, I/O racks, and control peripherals in demanding industrial environments. Fixed resistor inrush current limiting eliminates warm-start reset delays, ensuring reliable uptime in continuous-operation facilities.
Key Features
- 480W rated output with 20A output current at 24V DC (18A at 28V DC)
- Wide-range three-phase input: 380–480V AC, 50–60 Hz; handles ±15% voltage variations
- Compact DIN rail form factor minimizes control panel footprint
- 92% electrical efficiency reduces heat and operating costs
- LED status indicators for power and fault monitoring
- Inrush current limiting via fixed 47Ω resistor—no thermistor reset required
- UL508, CE, EMC, IEC/EN compliant for global installations
- NEMA IP20 enclosure rating suitable for control cabinets and racks
