The 1606-XLP50E belongs to the Compact tier of the Allen-Bradley Bulletin 1606-XL family. This unit fits small control panels, machine junction boxes, and remote enclosures where space is limited. Specifically, it converts wide-range single-phase AC or DC input into a regulated 24V DC output. Its compact 75 × 45 × 91mm body leaves room for relays, terminals, and other devices on the same DIN rail.
The 1606-XLP50E delivers 50W of rated output power with a typical efficiency of 89%. Output voltage is adjustable from 24V to 28V DC through a front-access potentiometer. This adjustment range lets users compensate for voltage drop on long feeder cables or trim the rail for sensitive sensors. Meanwhile, the output current reaches 2.1A at 24.5V, which covers small PLC racks, sensors, and indicator lamps.
Input specifications cover a nominal 100-240V AC range with an operational span of 85-264V AC, plus 85V DC input support. Hold-up time exceeds 171ms typical at 230V AC, which supports ride-through during brief power dips. Furthermore, ripple and noise stay at or below 50mV maximum, keeping the DC rail clean for analog signals. The unit carries UL 60950-1, cUL, and CE marks under the standard Bulletin 1606 approvals.
Note that this model offers no power boost. Therefore, size the load against the 2.1A continuous rating rather than relying on peak headroom. For panels with high inrush loads, the Performance series may suit better.
The 1606-XLP50E measures 75mm high, 45mm wide, and 91mm deep, with a body weight of 0.24 kg. Its IP20 housing fits inside control cabinets and provides finger-safe protection. Operating temperature starts at -10°C, while storage temperature starts at -40°C for non-operating conditions. Relative humidity runs from 5% to 95% non-condensing, and the spring clamp terminals accept standard control wire sizes.
The compact footprint makes this model a good fit for distributed 24V supplies near the load. Besides the small size, the spring clamp terminals speed up wiring because no torque setting is needed. Moreover, the unit mounts on standard 35mm DIN rail or on a flat surface with an optional bracket.
First, snap the 1606-XLP50E onto a standard 35mm DIN rail using the rear clip. For flat surfaces, use the optional wall mounting bracket instead. Keep ventilation clearance above and below the housing so convection cooling works properly.
Next, wire the input to the L and N terminals and connect protective earth to PE. The spring clamp terminals open with a small screwdriver, so no terminal torque setting is needed. Then wire the output to the + and – terminals and confirm the 24V DC factory setting before energizing sensitive loads. Finally, verify the total load stays within 2.1A, since this model has no power boost reserve.

Q1: What input voltages does the 1606-XLP50E accept?
A: The unit accepts 100-240V AC nominal input with an operational range of 85-264V AC. It also supports 85V DC input for battery-backed systems.
Q2: Does this model offer a power boost?
A: No. The 1606-XLP50E provides no power boost, so the load should stay within the 2.1A continuous rating at 24.5V.
Q3: Does the 1606-XLP50E include communication ports?
A: No. It has no communication interface and no DC OK relay contact. Status monitoring must rely on external devices wired to the output rail.
Q4: How large is the unit?
A: The body measures 75 × 45 × 91mm and weighs 0.24 kg. This compact size suits small enclosures and distributed supply layouts.
Q5: What is the typical efficiency of this power supply?
A: The 1606-XLP50E reaches 89% typical efficiency, which keeps heat generation low inside small, sealed cabinets.
