Allen-Bradley 80026-518-01 DC Switching Power Supply

Configured for DC voltage conversion and multi-rail distribution in Allen-Bradley industrial chassis, the Allen-Bradley 80026-518-01 (80026-518-01 DC Power Supply) provides direct physical/electrical execution.

Suffix Breakdown & Model Matrix

The 80026-518-01 identifier specifies a multi-output DC switching power supply within the 80026 platform architecture. The base catalog number 80026-518 defines the 56 VDC input processing circuitry and multi-rail power transformer design, while the revision suffix 01 indicates internal circuit board layouts and factory component standards.

Hardware Specifications

Backplane Bus Communication Velocity & DC Power Regulation

The Allen-Bradley 80026-518-01 switching power supply converts a 56 VDC primary input into seven isolated DC power rails (5 VDC, 15 VDC, and 24 VDC) delivering up to 5 A total current. Supporting high backplane bus communication velocity and deterministic I/O execution across connected Allen-Bradley chassis backplanes, the module provides stable voltage regulation across an extended operating range of -40 to +70 deg C. Onboard filtering circuitry suppresses line transients and electromagnetic interference in high-density rack configurations.

Frequently Asked Questions

Q: What input supply parameters are required to operate the 80026-518-01 module?

A: The power supply module requires a nominal 56 VDC primary input source to generate its internal secondary output voltages.

Q: What secondary DC output voltage rails are provided by the 80026-518-01 power supply?

A: The module supplies seven regulated output channels providing 5 VDC, 15 VDC, and 24 VDC power rails at up to 5 A total combined current.

Q: Can the 80026-518-01 power supply be hot-swapped while the main DC feed is live?

A: No, incoming 56 VDC power must be completely disconnected before inserting or removing the power supply module to prevent arcing and connector damage.

Field Installation Guidelines

1. Disconnect and lock out all 56 VDC incoming supply lines prior to starting the module installation.
2. Wear an anti-static wrist strap connected to chassis ground before handling the power supply unit.
3. Slide the 80026-518-01 module into its designated rack position until the backplane connectors align properly.
4. Tighten all chassis retaining screws firmly to establish mechanical retention and low-impedance protective earth grounding.
5. Connect input wiring verifying correct polarity (+56 VDC and return) before energizing the main DC source.
