The 1606-XLE120EN belongs to the Allen-Bradley Essential family of switched-mode power supplies. This unit provides a reliable and cost-effective solution for industrial control panels that require a stable 24V DC source. Specifically, it converts standard 100-120V AC single-phase power into a regulated 24V DC output capable of delivering 5A continuously. The slim 32mm housing saves valuable DIN-rail space in compact enclosures.
The 1606-XLE120EN delivers 120W of output power with a typical efficiency of 90%. The output voltage is adjustable from 24V to 28V DC via a front-access potentiometer. This flexibility allows users to compensate for voltage drops across long cable runs or to fine-tune the supply for sensitive loads. Additionally, the unit provides a dynamic power boost of 120% (up to 6A) at ambient temperatures below 45°C, which helps handle high inrush currents from contactors or capacitive loads.
Input specifications include a nominal voltage of 100-120V AC with an operational range of 90-132V AC at 50/60 Hz. The power factor is typically 0.59 at 120V AC. Furthermore, an NTC inrush current limiter keeps the peak input current at approximately 45A, protecting upstream circuit breakers. The hold-up time is greater than 78ms at 240V AC input, ensuring ride-through during brief power interruptions.
The 1606-XLE120EN measures 124mm in height, 32mm in width, and 117mm in depth, with a weight of 0.50 kg. The housing carries an IP20 protection rating, making it suitable for installation inside control cabinets where finger-safe protection is required. Operating temperature ranges from -10°C to +70°C, though output power derates above 60°C at 3W per degree Celsius.
For reliability, the unit features a Mean Time Between Failure (MTBF) of 740,000 hours at 40°C according to SN29500 standards. The screw terminals accept standard wire sizes for both input and output connections. Moreover, the DC OK relay contact provides a dry signal for remote monitoring of output status.
First, mount the 1606-XLE120EN onto a standard 35mm DIN rail by snapping the rear clip into place. Alternatively, use the optional 1606-XLB wall mounting bracket for flat-surface installations. Ensure adequate ventilation clearance above and below the unit to allow convection cooling.
Next, connect the input wires to the L and N terminals, and the protective earth to the PE terminal. The output terminals are clearly marked with + and – polarity. Use screw terminals with a tightening torque of approximately 0.5 Nm. Finally, verify the output voltage setting before connecting sensitive loads; the factory default is 24V DC.

Q1: What is the input voltage range for the 1606-XLE120EN?
A: The unit accepts 100-120V AC nominal input, with an operational range of 90-132V AC. It supports 50/60 Hz line frequency.
Q2: Can this power supply provide more than 5A?
A: Yes, below 45°C ambient, the 1606-XLE120EN offers a 120% dynamic power boost, delivering up to 6A for short durations to handle inrush loads.
Q3: Does the 1606-XLE120EN have a communication port?
A: No. The unit provides a DC OK relay contact for status signaling, but it does not include any serial or network communication interface.
Q4: What is the typical efficiency of this model?
A: The 1606-XLE120EN achieves a typical efficiency of 90.0% at 120V AC input, which minimizes heat generation inside the cabinet.
Q5: Is a wall mounting kit included?
A: No, the standard package includes the unit for DIN-rail mounting. The optional 1606-XLB bracket must be ordered separately for wall mounting applications.
