1606-XLP15B Allen-Bradley Slim Power Supply | Bulletin 1606-XL | 12 V DC 15 W
This 1606-XLP15B is a slim switched-mode supply in the Allen-Bradley Bulletin 1606-XL family. It holds a steady 12 V DC rail at 1.3 A and 15 W. The housing is 22.5 mm wide, which saves rail space in crowded cabinets. Hold-up time runs above 46 ms at 100 V AC. Efficiency sits at 82.5% typical, with losses near 3.2 W. Ripple peaks at 75 mVpp. Screw terminals take solid and stranded wire. Use it for sensors, relays, and small control loads.

Why 12 V at 1.3 A Works Here
- Feeds relay coils and 12 V proximity sensors.
- Trim range to 15 V helps offset cable drop.
- 3.2 W losses keep cabinet heat low.
- 46 ms hold-up rides through short input dips.
- Narrow body fits shallow and crowded panels.
Devices That Match
- 12 V sensor rails on conveyor and packaging lines.
- Relay and contactor control circuits.
- HMI backlight and small display supplies.
- Signal lamps and tower light branches.
- Legacy panels with a 12 V DIN rail rail.
Mounting Steps
- Snap the clip onto 35 mm DIN rail.
- Land input wires first, then output wires.
- Torque the screw clamps to a firm seat.
- Keep a small gap on each side for airflow.
- Set trim near 12 V unless loads need more.
Upkeep Checklist
- Read the output at no load, then at full load.
- Re-check screw torque on each service visit.
- Blow dust from the case vents.
- Confirm derating above +60 °C in hot panels.
- No dip switches, no firmware, no setup tools.
Certification
- UL 60950-1
- cUL

Oiltech Controls Review
- At 1.3 A, this unit covers most 12 V control loads.
- The 82.5% efficiency beats many older 15 W units.
- Trim to 15 V is a useful field advantage.
- Ripple of 75 mVpp is fine for relays and sensors.
- Stock it where 12 V sensor rails still run.

FAQ
Q: What current can I draw at 12 V?
A: 1.3 A nominal, and the range runs to 1.0 A at higher trim. Size loads near 1.0 A for margin. Relay inrush is the usual limit.
Q: Why does the output range reach 15 V?
A: The trim allows a boost for long cable runs. Keep it near 12 V unless the load needs more. Higher trim lowers available current.
Q: Is 75 mVpp ripple a problem for sensors?
A: No, most 12 V industrial sensors tolerate it. Add a local capacitor for analog signals. Check the sensor datasheet before you commit.
Q: Should I pick this unit or the 5 V XLP15A?
A: Pick this one for relay and 12 V sensor loads. Pick the XLP15A for 5 V logic boards. Same body width, different rail.
Q: How much derating applies in a hot panel?
A: Derate 0.4 W/°C from +60 to +70 °C. At +70 °C you have about 11 W. Size the load for the hottest day in the cabinet.
