Allen-Bradley MOX12/4U-P3509B 80026-173-23 Switching Power Supply

Description

The Allen-Bradley MOX12/4U-P3509B, identified under Rockwell part number 80026-173-23, is an industrial-grade DC/DC converter and Switching Power Supply manufactured by Absopulse Electronics Ltd. As shown in the nameplate image labeled image_7d9ee6.jpg, this unit functions as a high-density power conversion module designed for demanding automation networks, operating on a nominal 48 VDC input with an allowable swing between 42 VDC and 58 VDC. It converts primary supply currents into multiple isolated direct current output rails—ranging from +5.3 VDC up to +/-24 VDC—to simultaneously drive control electronics, logic processing boards, and remote field devices. Housed in a durable chassis frame with integrated ventilation slots, this system maintains high operational efficiency and electrical isolation across common grounding groups.

Features

• Wide-range direct current input capability optimized for nominal 48 VDC industrial battery banks or supply buses.
• Multi-rail power distribution providing independent positive, negative, and dual-voltage direct current outputs from a singular enclosure.
• Integrated ventilation slots distributed across the metal enclosure to enhance passive and system airflow thermal dissipation.
• Segmented common return networks (COM1 through COM5) to provide electrical isolation between distinct processing loops.

Applications

• High-reliability DC/DC power conversion within centralized industrial control cabinets.
• Multi-voltage rail distribution for processing hardware, diagnostic racks, and sensor networks.
• Telecommunications and industrial power distribution networks utilizing 48 VDC primary infrastructure.

Installation Guidelines

• Input Polarity Verification: Confirm input DC power lines strictly match the designated positive and negative landing terminals before applying voltage to prevent damage to internal switching topologies.
• Airflow Management: Maintain adequate clearance around the perimeter ventilation openings of the chassis to allow unimpeded heat dissipation and keep internal components within safe operating margins.
• ESD Mitigation: Always handle this unit within an ESD-safe workspace and wear a properly connected grounding wrist strap to defend sensitive internal regulator circuits against static discharge.
