Description
Pioneer Magnetics PM3327A-6-1-2-C Power Supply
Product Introduction
The Pioneer Magnetics PM3327A-6-1-2-C is an industrial power-supply assembly associated with Pioneer Magnetics and identified in multiple industrial automation and semiconductor-equipment spare-parts records. The commonly referenced assembly number is 118661, and one procurement record also identifies P/N 4001-0318 and describes the unit as a 48 V power supply. Other records associate the same PM3327A-6-1-2-C assembly with Qcept equipment, including the ChemetriQ-3000 platform.
The Pioneer Magnetics PM3327A-6-1-2-C should be treated as an equipment-specific power-conversion component rather than a general-purpose PLC power module. Its job is to provide the electrical supply required by the host machine’s electronics or subsystem. This distinction matters when sourcing an obsolete or difficult-to-find unit because output voltage, current capability, connector arrangement, protection behavior, and mechanical mounting all have to match the original installation.
There is an important specification issue with this particular part number. Available secondary records are not electrically consistent: one current listing describes 180 V output at 1200 W, while another industrial record identifies the same model as a 48 V power supply with P/N 4001-0318. That conflict is enough reason not to convert either figure into a guaranteed specification for a product page without additional primary documentation. The safest identification is therefore Pioneer Magnetics PM3327A-6-1-2-C, assembly 118661, with the output configuration verified from the physical label and host-equipment documentation.

Main Features and Engineering Considerations
Equipment-Specific Power Conversion
The is best understood as an equipment power subsystem. The part does not provide PLC logic, field I/O, or industrial-network communications. Its value is in supplying the electrical power required by the host machine.
Assembly Identification
The 118661 assembly number appears rly with and is useful when matching a physical spare against procurement records. Some records also associate 4001-0318 with the unit. Keep all numbers from the nameplate in the purchasing description rather than relying on alone.
Critical Output-Voltage Verification
This is the most important engineering issue for this part. A secondary record identifies the unit as a 48 V power supply, while another identifies an 180 V / 1200 W output. These are not interchangeable electrical specifications. Before installing a replacement, verify the output marking, input requirements, connector pinout, polarity, and host-equipment part number.
Legacy Semiconductor-Equipment Application
The appears in records associated with Qcept equipment, including a ChemetriQ-3000 application. For this type of equipment, a power supply that appears electrically similar may still have incompatible connectors, mounting dimensions, startup characteristics, or protection thresholds.
Application Scenarios
- Qcept semiconductor inspection equipment
- ChemetriQ-3000 equipment records
- Semiconductor manufacturing equipment
- Industrial electronic equipment
- Replacement of Pioneer Magnetics -series power assemblies
- Maintenance of legacy equipment requiring the 118661 assembly
Engineer’s Guide: Field Pitfalls
1. Do not assume 48 V from the model number.
A secondary record identifies this exact model as a 48 V power supply, but another source gives 180 V / 1200 W. The actual unit should be checked before replacement.
2. Record every identifier.
Capture , assembly 118661, P/N 4001-0318, serial number, revision, and host-equipment part number where available.
3. Check the connector pinout.
Do not assume that another Pioneer Magnetics PM33-series supply has the same connector assignment simply because the housing looks similar.
4. Verify startup behavior.
For semiconductor equipment, output ramp characteristics, transient response, and protection behavior can matter as much as nominal voltage.
5. Confirm the host equipment.
The same model designation should not automatically be treated as universal across every application. Qcept-related records provide useful application context, but the machine’s own documentation should control final compatibility.
6. Test under the actual load profile.
For a replacement unit, check output voltage at startup, steady state, and representative machine load before returning the equipment to production.
Frequently Asked Questions
What is Piognetics ?
It is a Pioneer Magnetics industrial power supply, commonly identified with assembly 118661.
What is assembly 118661?
118661 is repeatedly associth the designation in industrial spare-parts records.
Is a 48 V power supply?
A secondary industrial record identifies it as a 48 V power supply, but another source gives a different electrical rating. Therefore, 48 V should be treated as a reported configuration rather than a universally verified specification for every unit carrying this designation.
Is it a 1200 W power supply?
A current secondary listiribes a unit as 180 V / 1200 W. Because this conflicts with the 48 V description found elsewhere, the 1200 W rating should be verified against the actual nameplate before use.
Is associated with Qcept?
Yes. Multiple records associate the part with Qcept equipment, including the ChemetriQ-3000 platform.
Procurement Note
For Piognetics , the model number alone is not sufficient to establish the electrical specification with confidence. The recommended procurement description should retain and any additional P/N found on the original unit, particularly 4001-0318.
Before approving a replacement, verify the input voltage, output voltage, output current/power, connector pinout, mechanical dimensions, revision, and host-equipment model against the original. The conflicting secondary descriptions of 48 V versus 180 V / 1200 W make this a case where nameplate verification is more important than copying a reseller specification into a purchasing database.
