FAQ

Q: What input power does the 80026-518-01-R require?
A: The unit requires a 56 VDC input source. It is not an AC-input supply; ensure your upstream power source provides regulated 56 VDC.

Q: Which output voltages are available?
A: The supply delivers 5 VDC at 5 A, 15 VDC at 2 A, and 24 VDC at 1 A across seven independent output circuits.

Q: Is this a linear or switching power supply?
A: The 80026-518-01-R uses switching power conversion technology for high efficiency and compact size compared to linear designs.

Q: Can this unit be used in new ControlLogix systems?
A: The supply is optimized for legacy Allen-Bradley control platforms and drive systems. Verify voltage and current requirements against your specific chassis before integration.

Installation Guide

• Mount the supply on a panel or DIN rail inside the control cabinet with adequate ventilation clearance.
• Connect the 56 VDC input to the primary power terminals, observing correct polarity.
• Route 5 VDC outputs to logic and processor circuits, 15 VDC to interface electronics, and 24 VDC to relays and sensors.
• Install individual fuses on each output circuit for branch protection.
• Verify output voltages with a digital multimeter before connecting sensitive control modules.

Selection Tips

• Current Budget: Sum the load currents of all devices on each rail and verify against the 5 A / 2 A / 1 A ratings.
• Input Source: Confirm your plant provides 56 VDC. If only AC is available, add an upstream AC/DC rectifier module.
• Thermal Management: At full 88% efficiency, calculate waste heat and ensure cabinet ventilation prevents thermal derating above 50°C ambient.
• Legacy Compatibility: This supply is commonly found in 80190-series and PowerFlex 7000-class installations. Verify assembly reference MOX720-P4668E for exact replacement.
