PW482-50 | Yokogawa PW482 AC Power Supply Module
The Yokogawa PW482-50 is an AC input power supply module in the PW482 family. It accepts 220–240 V AC power and is specified for operation with an ambient temperature option from −20°C to +70°C. The module connects to its host system through an exclusive connector.
For maintenance and replacement planning, verify the suffix configuration, AC supply conditions, connector compatibility, and the host system’s approved power-supply arrangement.

Specification boundary: The supplied data does not identify the module’s DC output rails, output current ratings, redundancy behavior, or supported host-system models. Confirm these details in the relevant Yokogawa hardware documentation before engineering a replacement.
Integration Notes for Maintenance Engineers
- Check the AC feed. Confirm the supply falls within the stated 220–240 V AC ±10% range and frequency tolerance.
- Review power capacity. Use the 230 VA maximum consumption figure when checking the upstream supply and panel power budget. Apply the system manual’s design margins.
- Inspect the dedicated connector. Confirm the mating interface and module orientation against the installed equipment. Do not force an incompatible connector.
- Confirm temperature suitability. Check the actual cabinet ambient temperature and verify that the −20°C to +70°C option matches the installation.
- Follow the host-system procedure. Isolate power and observe the manufacturer’s removal, installation, and startup instructions. Do not assume hot replacement is supported.
- Validate after replacement. Check system power status, controller startup, and downstream module operation using the host system’s approved maintenance procedure.
Equipment Fit and Typical Use
The PW482-50 is intended for compatible Yokogawa control-system installations that specify the PW482 AC input power supply and its connector interface. Confirm the exact system and hardware revision before ordering.
- Yokogawa control-system cabinets: Replacement planning for installations designed around the PW482 supply module.
- Process automation: Power-supply maintenance in compatible control and monitoring cabinets used in industrial process facilities.
- Plant maintenance and turnaround work: Spare inventory for planned replacement or troubleshooting of the specified power module.
- Temperature-demanding cabinets: Applications requiring the stated −20°C to +70°C temperature option, subject to the system’s own environmental limits.
These are general application contexts. The supplied specifications do not establish compatibility with every Yokogawa DCS or I/O platform.
Diagnostic Checks
The provided product data does not specify onboard diagnostic LEDs, alarm contacts, or fault codes. Troubleshooting should therefore begin with the module’s documented system indications and cabinet-level checks.
| Observed issue | Checks to perform |
|---|---|
| System does not power up after replacement | Verify the AC feed, upstream protection, module seating, connector engagement, and correct model selection. |
| Power module appears inactive | Measure the input supply using approved electrical safety procedures and compare it with the specified voltage and frequency range. |
| Intermittent system power | Inspect connector seating, terminal integrity, cabinet temperature, and upstream supply stability. |
| Replacement module does not fit | Compare the complete model code, connector, mechanical arrangement, and host-system documentation. |
| Power is present but the system reports an error | Review system diagnostics and downstream module status. The fault may be outside the power supply itself. |
Global PLC Spare HUB's Insight
When selecting a replacement power supply, matching the family name is not enough. Confirm the full PW482-50 suffix, AC input requirements, temperature option, connector, and host-system compatibility. The stated 230 VA consumption is an input power figure; it should not be treated as a DC output rating.
During a planned replacement, record the original module code and system alarms before removal. After installation, verify stable system startup and review the controller and I/O status. If the system’s documentation does not clearly identify replacement procedures, consult the relevant Yokogawa manual before attempting a live change.

Frequently Asked Questions
Q1: Is PW482-50 interchangeable with another PW482 suffix?
Do not assume interchangeability. Compare the protection and function codes, temperature specification, connector, and host-system requirements with the installed unit and Yokogawa documentation.
Q2: Does the 230 VA figure indicate the module’s DC output capacity?
No. The supplied specification identifies maximum power consumption. Confirm the DC output voltage and current ratings separately before calculating the load capacity.
Q3: What should I include when checking cabinet power suitability?
Check the AC voltage and frequency, upstream circuit capacity, module power consumption, cabinet temperature, and any system-specific power distribution requirements. Use the host-system manual for sizing criteria.
Q4: Can I replace this module while the control system remains energized?
The supplied information does not confirm hot-swap capability. Follow the documented shutdown and replacement procedure for the exact host system; isolate power unless the manufacturer explicitly permits live replacement.
Q5: How can I reduce the risk of ordering the wrong spare?
Send a clear nameplate photo, the complete PW482-50 model code, and the host-system model or cabinet identification. Compare connector details and system documentation before placing the order.
