Technical Parameter Matrix

Industrial Control Integration

The unit utilizes deterministic power delivery protocols essential for PowerFlex drive control logic. It maintains internal bus stability through consistent voltage regulation, ensuring that firmware flash compatibility and EtherNet/IP communication modules connected to the drive backplane remain synchronized. The fanless design reduces vibration-induced coupling into sensitive signal circuits, while the high-efficiency output prevents thermal drift in cabinet-mounted control racks.

Standard Scope of Delivery

• Allen-Bradley 80026-088-01 Switching Power Supply unit.

• Note: Terminal block connectors are integrated into the unit housing.

• Note: Documentation such as manuals or specific calibration certificates are not included unless specified in the procurement contract.

Mounting and Environmental Deployment

• Mounting Orientation: Supports both vertical panel mounting and standard DIN-rail installation.

• Cooling Requirements: Device utilizes convection cooling; ensure a minimum clearance of 50 mm above and below the unit for heat dissipation.

• Wiring: Use copper conductors rated for at least 75 deg C. Ensure the protective earth (PE) terminal is securely bonded to the control cabinet backplane to minimize electromagnetic interference (EMI).

• Environment: Maintain within 5-95% RH non-condensing to prevent insulation breakdown.

Technical FAQs

• Does this power supply support hot-swapping? No, the unit must be de-energized and disconnected from the input source before removal or installation to prevent arcing.

• What is the behavior of the Overvoltage Protection? If the output exceeds safe thresholds, the supply will trigger an internal latch-off, requiring an AC input power cycle to reset.

• Can the output voltage be adjusted in the field? The unit is rated for 56 VDC nominal; adjustment range depends on specific revision levels—consult the internal potentiometer markings.

• Is the unit susceptible to harmonic interference? It includes input filtering designed to meet industrial standards for 47-63 Hz environments.

• What happens during an Overtemperature event? The internal thermal switch will cause the unit to shut down; it will automatically restart once the internal temperature drops below the thermal hysteresis threshold.

• Are there specific requirements for the input ground? Yes, the chassis must be grounded to the protective earth to ensure effective operation of internal surge suppression circuits.

• What is the maximum current draw? The unit draws 3.4 A at nominal input load conditions.

• Can this unit be used in redundant configurations? It does not include built-in diodes for parallel redundancy; external blocking diodes are required to prevent back-feeding between supplie
