What Is the Allen-Bradley 1606-XLP25A Power Supply?

The Allen-Bradley 1606-XLP25A is a compact DIN rail power supply from the Bulletin 1606-XL series. It delivers a stabilized DC 5 V output at 25 W rated power, making it a dependable choice for low-voltage control circuits in oil and gas installations.

Because field panels often fail on power conversion rather than on logic, this module is engineered for harsh oil and gas environments. Its wide AC 100...240 V nominal input and DC 110...300 V input range let one model serve multiple supply arrangements. In addition, the 5 A nominal output current covers small relay, sensor and interface loads.

Key Features and Technical Specifications

• Input voltage: AC 100...240 V nominal; DC 110...300 V.
• Output voltage: DC 5 V nominal, adjustable from 5...5.5 V.
• Output current: 5 A nominal (range 5...5.0 A).
• Rated power: 25 W.
• Efficiency: 80.0% typical.
• Operating temperature: -10...+70 °C.
• Protection rating: IP20 for DIN rail, enclosure mount.
• Dimensions (H×W×D): 75 × 45 × 91 mm.
• Weight: 240 g.
• Approvals: UL 60950-1 / cUL / CE marked.

The adjustable output is the most useful field feature. Technicians can trim the DC 5 V nominal output up to 5.5 V to offset voltage drop across long control wiring. Furthermore, the 80.0% typical efficiency limits heat build-up inside sealed enclosures.

How Does This unit Compare with Other Power Supply Categories?

Power supplies are often grouped by output class and mounting style. The comparison below uses only verified data for this model.

• Versus 24 V system supplies: This unit provides DC 5 V nominal output, so it suits 5 V logic and interface loads rather than 24 V field devices.
• Versus higher-power 1606-XL models: This unit is rated 25 W, so larger models in the series serve heavier loads.
• Versus open-frame supplies: This model uses DIN rail mount with spring terminals and an IP20 rating.
• Versus communication-capable controllers: It has no built-in ports and no communication protocol, because it is a power supply only.

For a plc power supply module replacement, these distinctions matter. Always match output voltage, current and mounting before substitution.

Where Is This Power Supply Used in Oil and Gas Operations?

Low-voltage DC rails appear throughout upstream and midstream facilities. This unit fits panels where a stable 5 VDC source is required.

For example, it can feed signal conditioning modules and interface relays in a wellhead control panel. It can also supply monitoring electronics in a compressor station. In addition, it suits remote instrument enclosures that accept a wide AC or DC input. Because the unit tolerates -10...+70 °C, it remains dependable in hot process areas and cold climates alike.

Installation and Setup Guidance

Mount the unit on a standard DIN rail inside an enclosure that supports the IP20 rating. Connect input wiring to the spring terminals and confirm the supply matches AC 100...240 V nominal or DC 110...300 V. Next, set the adjustable output to the required level within 5...5.5 V. Finally, verify polarity and load current before energizing downstream devices.

Allow clearance for convection cooling, since the 25 W rating and 80.0% typical efficiency produce some heat. Keep the operating temperature within -10...+70 °C.

Maintenance and Reliability Practices

Inspect terminals periodically for tightness and discoloration. Check that enclosure temperature stays within the rated range during peak summer operation. Because the output is adjustable, confirm the setpoint has not drifted during routine rounds. These simple steps support reliability you can depend on in mission-critical panels.

Frequently Asked Questions
