The 1606-XL480EP belongs to the legacy Bulletin 1606-XL line and carries a PFC variant designation. This unit suits panels with single-phase mains that need a strong 24V DC rail. Specifically, it converts auto-selected 100-120V or 200-240V AC input into a regulated 24V DC output. The 480W rating covers PLC racks, I/O clusters, and field device loads in one DIN-rail package.
Rockwell lists this model as discontinued, with end of sale on 2017-10-30. The direct replacement is the 1606-XLE480EP. Buyers should confirm spares availability before designing the unit into new builds.
The 1606-XL480EP delivers 480W of rated output with 20A at 24V across 0-60°C ambient. Efficiency reaches up to 90.4%, based on the PULS OEM counterpart SL20.100, though the AB PFC variant may differ slightly. Output voltage spans 24-28V DC, so users can trim the rail for cable drop or sensitive loads.
Input specifications use auto-select between 100-120V and 200-240V AC, with continuous ranges of 85-132V and 184-264V. Furthermore, a 600W boost mode supplies 25A at 24V for short periods under 30 seconds, which covers peaks from contactors and motor starters. The PFC front end improves power factor and reduces harmonic current drawn from the mains. The unit carries UL 60950-1, cUL, and CE marks under the standard Bulletin 1606 approvals.
The 1606-XL480EP measures 124mm high, 220mm wide, and 102mm deep, with a weight of 2.5 kg. Its IP20 open-frame housing fits inside control cabinets with DIN-rail mounting per 1606-AP017. Operating temperature runs from 0°C to +70°C with derating above 60°C, while storage spans -25°C to +85°C. The manufacturer does not publish a relative humidity figure for this model.
For monitoring, this model includes no communication interface and no DC OK relay contact. Therefore, integration relies on hardwired panel wiring rather than status signaling. Besides the power conversion, the auto-select input simplifies stocking because one unit covers both 120V and 240V mains.
First, mount the 1606-XL480EP onto a standard DIN rail per the 1606-AP017 instructions. Keep ventilation clearance above and below the housing because the open-frame design relies on convection cooling. Verify the single-phase input wiring matches the L, N, and PE terminals before energizing.
Next, confirm the input voltage falls within 85-132V AC or 184-264V AC, and check that the auto-select circuit has picked the correct range. Then wire the output to the + and – terminals and confirm the 24V setting before connecting loads. Finally, derate the output above 60°C ambient, and limit boost demand to under 30 seconds.

Q1: Is the 1606-XL480EP still in production?
A: Rockwell lists this model as discontinued with end of sale on 2017-10-30. The direct replacement is the 1606-XLE480EP.
Q2: What input voltage does this unit accept?
A: The 1606-XL480EP auto-selects between 100-120V and 200-240V AC. Continuous ranges cover 85-132V and 184-264V AC.
Q3: How long can this model deliver the 600W boost?
A: The boost supplies 25A at 24V for short periods under 30 seconds. Continuous output stays at 20A (480W) up to 60°C.
Q4: What does the PFC designation mean?
A: PFC stands for power factor correction. The front end reduces harmonic current and improves power factor, which suits installations with strict mains quality rules.
Q5: Does the 1606-XL480EP include a DC OK relay?
A: No. This model offers no DC OK relay contact and no communication interface, so status monitoring needs external devices.
