Allen-Bradley 1606-XLP25A Compact Power Supply

Configured for space-constrained industrial control applications, the Allen-Bradley 1606-XLP25A (1606-XLP25A Power Supply) provides direct physical execution of AC-to-DC voltage conversion, delivering a regulated 5 VDC output from a universal 100-240 VAC input.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

The 1606-XLP25A supports the operational stability of control hardware within deterministic networks by providing a consistent 5 VDC power source. By maintaining output regulation across varying line conditions, it minimizes the risk of voltage-related logic errors in high-speed I/O and communication modules. The module facilitates I/O density scaling by occupying minimal footprint, allowing for higher component concentration in limited-space enclosures. Firmware flash compatibility for connected communication devices is protected against transient power fluctuations, ensuring that the backplane bus communication velocity remains within nominal specifications during system operation.

Frequently Asked Questions

Q: Is this power supply capable of providing peak current for capacitive loads?

A: The 1606-XLP25A is designed for a rated 25 W output. While it accommodates standard operating currents, avoid exceeding the rated output capacity during start-up to prevent thermal shutdown or intermittent operation.

Q: Can the 5 VDC output be adjusted?

A: The 1606-XLP25A is a fixed-voltage power supply. It does not include an integrated potentiometer for output voltage adjustment; ensure the input voltage and environmental conditions are within the specified ranges to maintain the nominal output level.

Field Installation Guidelines

1. Install the unit on a standard 35 mm DIN rail in a vertical orientation to ensure proper convective cooling through the housing vents.
2. Maintain a minimum clearance of 50 mm above and below the power supply to prevent heat accumulation.
3. Terminate AC input wiring to the L and N terminals, ensuring the Protective Earth (PE) terminal is bonded to a low-impedance ground point to minimize electromagnetic interference (EMI).
4. Verify that the total load current does not exceed the capacity of the 5 VDC output terminals.
5. Use wire sizes appropriate for the intended current load, ensuring proper torque settings for the screw terminals to prevent overheating at the connection points.
