Core Product Summary
The Pioneer Magnetics PM3398B-6-1-3-E is a 1500 W-class AC-to-DC switching power supply from the manufacturer’s PM33xx PowerFactor series; units of this build are marked with the companion part number 80026-172-24. It accepts a wide-range AC input of 100–240 VAC at 50/60 Hz (23 A input rating) and provides a regulated 56 V DC output at 26.8 A.
As a PowerFactor-series unit, its input stage includes power-factor correction, converting the AC line into isolated, regulated DC for downstream industrial loads. The wide input range allows deployment on both 100–120 V and 200–240 V supply systems without input rewiring changes. Units in this series deliver continuous full power over a 0 °C to +50 °C ambient range and use latched overvoltage protection that clears after the AC line is removed for approximately 30 seconds and reapplied.

Detailed Product Overview
The PM3398B-6-1-3-E sits in the upper power range of the PM33xx PowerFactor series, Pioneer Magnetics’ line of AC-to-DC converters with power-factor-corrected input stages. With a 56 V DC, 26.8 A output, it delivers approximately 1.5 kW of continuous DC power, which places it in the class used for dense industrial load groups, auxiliary distribution rails, and telecom-style −48/56 V architectures rather than small panel supplies.
The wide-range 100–240 VAC input is the key integration benefit of this build. The same unit can be installed on a 120 VAC North American supply or a 230 VAC international supply without input hardware changes, and the PFC input stage keeps input current harmonics low on either line. The 23 A input rating defines the upstream circuit protection and wiring gauge the installation must provide.
The 56 V DC output deserves attention at specification time. Pioneer Magnetics builds the PM3398 family in multiple output-voltage configurations — 48 V builds of the same model family exist at 31 A, while this specific build provides 56 V at 26.8 A. Because the model-number suffix defines the electrical build, engineers should verify the output voltage and current against the unit nameplate before ordering, and treat the companion part number 80026-172-24 as the exact-build identifier when matching a replacement to an installed chassis.
Protection behavior follows the PowerFactor series convention: overvoltage shutdown latches, and the latch clears only after AC input is removed for roughly 30 seconds and reapplied. In racks without a remote input disconnect, this means a fault requires physical or contactor-based input interruption to recover. Thermal planning must also account for full-power delivery only up to +50 °C ambient, so cabinet ventilation should be sized for the unit’s heat dissipation alongside the loads it feeds.

Dimensions, Mounting & Connection Notes
- The unit is a rack/front-end format switching power supply of the PM33xx series; shipping weight for this part is listed at approximately 10 lb (≈4.5 kg).
- Input connection is to a 100–240 VAC, 50/60 Hz line; overvoltage shutdown recovery requires removing AC input for approximately 30 seconds.
- Cooling follows the PowerFactor series design (internal forced air); the mounting location must allow free airflow.
- Safety certifications for the series are referenced to UL1950, CSA 22.2 No. 950, and TÜV to EN60950.
FAQ
