Pioneer Magnetics PM3398B-6-1-3-E 80026-172-24 | Industrial Power Supply Module, 24 VDC

Description

Key Technical Specifications

A secondary technical listing reports 90–305 VAC input, 24 VDC output, 250 A output, and approximately 6 kW rated power for this exact designation. Those figures are useful for identification, but I would verify the original Pioneer Magnetics datasheet or nameplate before using them for cabinet design or electrical sizing.

There is particularly poor quality in the online specification trail for this part. One listing incorrectly describes the unit as an Allen-Bradley power supply with 240 VAC three-phase input and 172 kW power, while another identifies the same number as a generic controller. Those descriptions should not be used for engineering decisions.

Product Introduction

Pioneer Magnetics PM3398B-6-1-3-E 80026-172-24

The Pioneer Magnetics PM3398B-6-1-3-E 80026-172-24 is identified as an industrial power-supply module in the PM3398B family. Available technical records associate this exact assembly with high-power DC supply applications for industrial automation and control equipment.

The important point for maintenance teams is its electrical role. This is not a PLC CPU or conventional I/O module. If the associated control cabinet is experiencing simultaneous controller resets, contactor dropouts, or DC-bus undervoltage, the power-supply module and its upstream AC supply should be investigated before replacing individual control boards.

Application Scenarios & Field Pitfalls

Engineering Pain Point

A high-power DC supply failure can make a healthy automation system look completely dead. Controllers reboot. I/O drops offline. Contactors chatter. Network devices disappear. When several devices fail at the same time, check the common DC power source first rather than replacing five separate electronic modules.

Typical Applications

• Industrial Automation — High-current DC power distribution for control cabinets and automation equipment.
• Process Control — Centralized DC supply for electronic control hardware and associated instrumentation.
• Machine Automation — Power source for controllers, interfaces, and electrically controlled machinery.
• Specialized Test Equipment — Regulated DC power for high-current industrial electronic systems.

Technical Pitfalls to Avoid

1. Verify the nameplate before energizing.
   The online documentation for PM3398B-6-1-3-E is inconsistent. Do not assume the published 90–305 VAC / 24 VDC values are correct for your specific revision without checking the physical unit.
2. Do not confuse this part with an Allen-Bradley product.
   Several secondary pages incorrectly associate the part number with Allen-Bradley. The stronger identification trail points to Pioneer Magnetics.
3. Check output voltage under load.
   A supply can show the correct voltage with no load and collapse when the cabinet is energized. Measure both unloaded and loaded output conditions.
4. Inspect the upstream AC circuit.
   Blown fuses, contactor problems, phase loss, loose terminals, and damaged input wiring can produce symptoms that look like an internal power-supply failure.
5. Check high-current connections carefully.
   If the unit is operating around the reported 250 A output class, loose DC terminals can generate substantial heating and voltage drop. Inspect terminals for discoloration, thermal damage, and improper torque.
6. Do not replace the unit based only on a low-voltage alarm.
   Measure the voltage at the supply output and again at the downstream load. A significant difference indicates wiring, distribution, or connection resistance rather than necessarily a defective supply.
7. Check cooling.
   High-power supplies depend heavily on airflow. Blocked filters, failed fans, cabinet heat buildup, and excessive ambient temperature can cause thermal shutdown or accelerated component aging.
8. Verify the exact suffix.
   PM3398B-6-1-3-E and 80026-172-24 should be treated as one identification set. Do not substitute another configuration solely because the base model is the same.
9. Inspect DC-side capacitors and ripple.
   If control electronics repeatedly reset while the measured DC voltage appears close to nominal, check ripple and transient behavior with appropriate instrumentation.
10. Do not use contradictory web specifications for cabinet design.
    The published records contain obvious classification errors. Use the actual unit’s nameplate and OEM documentation for input protection, output current, environmental limits, and wiring.

• Pioneer Magnetics -6-1-3-E 80026-172-24-R — A closely associated part-number variant appearing in maintenance inventories. The “-R” designation should be verified with the supplier/OEM before treating it as electrically identical.
• Pioneer Magnetics HYRSP-1500-56 — A different Pioneer Magnetics industrial power-supply product. It may be relevant when evaluating alternative power architectures, but it is not a direct replacement.
• Pioneer Magnetics PM3300 Series — Related industrial power-conversion family referenced in secondary documentation. Individual models can differ substantially in output voltage, current, and mechanical configuration.
• Industrial 24 VDC Power Supplies — General replacement category for control-cabinet power systems. A generic 24 VDC supply should only be considered after verifying the ‘s actual current, transient, mechanical, and interface requirements.
• High-Current DC Power Supplies — Relevant alternative category where the application genuinely requires the reported high-current output class. Output-current capacity alone is not enough; input range, cooling, protection behavior, and load transient response must also match.
• Redundant DC Power Supply Systems — Useful for critical automation cabinets where loss of a single power converter cannot be tolerated. The redundancy architecture must be compatible with the downstream DC distribution design.
• Pioneer Magnetics Replacement Assemblies — Relevant when maintaining an existing installation without changing cabinet wiring or mechanical mounting. Exact revision and connector arrangement should be verified against the failed unit.
