- Multi-Parallel High-Current Planar Winding Custom Structure
Suffix code 6P: Six parallel enameled copper wire strands for primary single-phase winding, distributing input current across multiple conductors to lower single-wire current density and reduce winding heat generation
Suffix code 3P: Three groups of parallel laminated copper foil winding stacks for secondary output side, multi-layer thick copper foil minimizes high-frequency AC winding loss under continuous 18A large output current
Suffix code E enhanced grade encapsulation: High thermal conductivity flame-retardant epoxy resin fully encapsulates the entire planar magnetic core and multi-parallel winding assembly, enhancing heat transfer from winding heat sources to the aluminum rack heat dissipation baseplate to avoid excessive temperature rise during long-term full-load continuous operation
- High-Current PCB Fixed Layout Design
All secondary output power circuit traces adopt ultra-wide thick copper multi-layer PCB layout to reduce circuit conduction resistance and avoid abnormal heating under 18A continuous large current load. PCB footprint strictly follows drawing 80026-172-03 fixed layout specification
- Exclusive Connector Pin Definition
Front panel Elcon drawer-type hot-plug power connector pin assignment layout is uniquely defined by internal drawing code 80026-172-03. Pinout cannot be replaced with other PM3398B series variant connector layouts. Mismatched wiring will cause input circuit overcurrent, output overvoltage or short-circuit faults leading to permanent module internal high-power component burnout damage
The overall power conversion flow adopts the universal PM3398B base platform multi-stage AC-DC power conversion architecture. All electrical parameters, multi-parallel winding turns ratio and thermal encapsulation performance indicators are factory pre-calibrated and fixed according to drawing 80026-172-03 customized specifications.
The six-parallel primary winding and three-parallel secondary copper foil winding design disperses high operating current across multiple parallel conductive paths, drastically reducing winding current density and internal heat generation under heavy continuous load operation. The variable-speed forced air cooling fan dynamically increases airflow volume when internal temperature rises, maintaining stable magnetic core and circuit board operating temperature within safe threshold range during long-term full-load operation.
All fault protection trigger current, voltage and temperature threshold values are locked by factory firmware. Field users cannot adjust protection parameters through external configuration software or hardware potentiometers.
All mechanical rack mounting, single-phase power wiring, cabinet environmental layout and protective grounding installation rules follow the universal PM3398B base platform installation standard specifications, with one exclusive customized limitation:
Front panel Elcon single-phase input and DC output power connector wiring must strictly follow drawing 80026-172-03 fixed pin assignment definition. Cross-use of other PM3398B variant connector wiring pin layouts is prohibited. Mismatched wiring will trigger input overcurrent protection or output short-circuit fault and permanently damage module internal high-power components.

All general operation, maintenance, troubleshooting and spare parts storage specifications follow the universal PM3398B base platform maintenance standard rules, with exclusive customized precautions for this variant:
- Spare part replacement restriction: When replacing damaged modules on production heavy-load equipment, only the complete full part number PM3398B-6P-1-3P-E with internal drawing reference code 80026-172-03 can be used as qualified replacement spare parts. Other PM3398B series suffix variant models with different parallel winding configuration codes and drawing numbers cannot be interchanged for equipment replacement use. Mismatched variants cannot provide stable 18A 48VDC high-current output and will cause rear-end laser equipment and battery charging system burnout damage.
- Engineering document and procurement specification requirement: All equipment system schematic design, cabinet wiring PCB layout, production equipment BOM and spare parts procurement documents must record the complete full part number including parallel winding suffix codes and exclusive internal drawing reference number 80026-172-03. Generic PM3398B base model number cannot replace the complete full part number for engineering design and procurement work.
