The 1606-XLE120E belongs to the Allen-Bradley Bulletin 1606-XL Essential series. This switched-mode power supply delivers a stable 24V DC output with 120W rated power. Engineers choose it for control cabinets, machine building, and process automation systems. The unit accepts single-phase wide-range AC or DC input. Furthermore, its adjustable output range of 24 to 28V DC supports flexible field wiring. The DC OK relay contact provides a simple status signal to your controller. Therefore, maintenance teams can monitor supply health without extra hardware. This compact unit fits DIN rail or wall mounting positions. Its 94.3% typical efficiency keeps heat loss low inside enclosures. Meanwhile, the dynamic 120% power boost handles short load peaks at up to +45°C. In short, the 1606-XLE120E balances cost, reliability, and easy installation.
First, the input stage accepts 100 to 240V AC nominal, with an operational range of 90 to 264V AC. It also supports 110 to 300V DC input for battery-backed systems. Next, the output provides 24V DC nominal and stays adjustable from 24 to 28V DC. Output current reaches 5A maximum, giving 120W rated power. Moreover, ripple and noise stay at 50mV maximum, which protects sensitive loads. Hold-up time exceeds 80ms typical at 120V AC, so brief outages cause no disruption. Additionally, typical efficiency reaches 94.3%, and power losses sit near 7.3W typical. The power factor measures 0.91 typical. Protection covers overload and short-circuit events. A dynamic 120% power boost supports startup currents at up to +45°C.
The 1606-XLE120E has no built-in communication ports or protocols. Instead, a DC OK relay contact supplies a dry signal for status monitoring. This contact suits PLC digital inputs, alarm lamps, or panel indicators. For instance, wire the relay to a controller input to flag supply faults. Consequently, commissioning stays simple and costs remain low. If you need fieldbus monitoring, add an external module. Otherwise, the relay contact covers most basic diagnostics.
The housing measures 124 × 32 × 102 mm and weighs 0.44 kg. It carries an IP20 protection rating, so it suits protected cabinet interiors. Operating temperature spans -25 to +70°C, and humidity tolerance reaches 5 to 95% non-condensing. Screw terminals accept standard field wiring. The narrow 32mm width saves valuable DIN rail space. Besides, wall mounting holes offer layout flexibility. Finally, storage temperature starts at -25°C, per published Rockwell data.
Begin by snapping the unit onto a 35mm DIN rail or fastening it to a wall. Next, connect the input wires to the screw terminals and torque them to the specified value. Then, set the output voltage between 24 and 28V DC to match your load. After that, wire the DC OK relay contact to your monitoring circuit. Ensure adequate ventilation around the housing during operation. Finally, verify the output with a meter before energizing downstream equipment. The 1606-XLE120E ships as an active product with full Rockwell support.
