Description
Metso Automation A413337 SPUC Power Unit Module
Product Overview
The Metso Automation A413337 is a high-current SPUC power unit module used as part of the power architecture in legacy Metso Automation control systems. It is fundamentally different from a PLC CPU, I/O card, or communication module. Its job is to accept the plant AC supply and provide the DC power required by associated control electronics and system hardware. Available technical records identify the A413337 with a 100–240 VAC input range, 45–65 Hz operating frequency, and a maximum output capacity of 60 A.
In practical terms, the Metso Automation A413337 sits upstream of multiple automation components. That makes its failure characteristics different from a single I/O module: an unstable or failed power unit can affect several controllers, I/O assemblies, and communication devices at the same time. Product records identify the DC output as approximately 18–27.2 VDC. Because detailed primary documentation for this obsolete component is difficult to locate, that output range should be confirmed against the installed system documentation and the nameplate before a replacement is commissioned.
The Metso Automation A413337 is therefore most relevant to maintenance teams supporting older Metso control installations where the original power architecture remains in service. It is listed as discontinued, so procurement is generally a matter of identifying correct legacy stock rather than assuming that any modern 24 VDC industrial power supply can replace it. Electrical capacity, mechanical installation, system distribution, protection, and the original Metso power architecture all need to be checked.
Product Introduction
A controller fault that appears across several I/O stations at once is often a power-distribution problem, not several simultaneous module failures. The Metso Automation A413337 occupies this system-level power position, with a documented 100–240 VAC input and 60 A maximum output rating.
For legacy Metso installations, the part is particularly relevant to DCS system maintenance, control-system power replacement, and legacy automation upgrades. Do not treat it as a generic 24 VDC supply without first confirming the original SPUC architecture.

Major Features / Practical Advantages
High-Capacity System Power
The is rated for up to 60 A, placing it in a very different category from small DIN-rail supplies used for individual instruments or isolated control circuits. Its intended role is system-level power conversion within a Metso Automation installation.
That capacity matters during fault diagnosis. If several control modules disappear from the system simultaneously, checking the DC bus and power distribution can be more productive than immediately replacing individual controller or I/O cards.
A413337
Wide AC Input Range
The specified 100–240 VAC input range and 45–65 Hz frequency range provide compatibility with common industrial AC supply arrangements.
For a replacement project, however, the incoming supply should still be measured under normal operating conditions. A wide input rating does not compensate for poor upstream protection, loose terminals, excessive voltage drop, or an overloaded distribution circuit.
60A Output Capability
The 60 A maximum output is one of the most useful identification characteristics for the . Available records consistently describe it as a 60 A Metso Automation power supply.
This also provides a practical distinction from the related A413331, which is documented in product records as a 35 A SPU power unit. The two should not be substituted solely because both are Metso power-unit products.
Legacy Metso System Support
The remains relevant where an older Metso Automation control system cannot simply be migrated to a current power architecture. Replacement of the power unit can become a maintenance-critical task when the original installation is still responsible for continuous process control.
A failed power unit can produce misleading symptoms: controller resets, communication loss, I/O station dropout, multiple module diagnostics, and intermittent system alarms can all originate from a common DC power problem.
Important Procurement Qualification
The is listed as discontinued. That changes the procurement approach.
For a new-surplus unit, inspect the original manufacturer label, complete part number, revision information, terminal condition, storage history, and evidence of previous installation. For refurbished equipment, request an actual load test rather than accepting a simple no-load voltage measurement.
A power supply that produces the correct voltage with no load can still fail when the control system demands substantial current. That distinction matters with a 60 A unit.

FAQ
What is the Metso used for?
The is a Metso Automation SPUC power unit module. Its primary role is AC-to-DC power conversion for the associated control-system installation rather than signal processing or controller logic.
Is a PLC or DCS I/O module?
No. It is a power supply / power unit module. It should not be selected as an analog, digital, communication, or CPU replacement.
What is the input voltage of ?
Available records specify 100–240 VAC at 45–65 Hz.
What is the output current?
The documented maximum output is 60 A.
Does output 24 VDC?
Available product records report an output range of approximately 18–27.2 VDC. Because this is a legacy component and detailed primary documentation is limited, the exact operating/output requirement should be confirmed against the original Metso system documentation before installation.
Can I replace with A413331?
Do not assume a direct replacement. A413331 is identified as a 35 A SPU power-unit module, while is identified as a 60 A SPUC power supply. The lower-rated unit may not satisfy the load requirements of the original system.
Can I hot-swap the ?
Do not assume unrestricted hot swapping. This is a high-capacity system power unit, and removing it can affect multiple control-system components. Follow the site’s approved maintenance, isolation, and power-distribution procedure.
Does have firmware?
It should not be treated like a PLC CPU or intelligent I/O module for firmware compatibility purposes. The critical procurement variables are the exact part number, hardware/revision identification, electrical ratings, mechanical arrangement, and compatibility with the existing Metso power architecture.
How should a used or refurbished be tested?
At minimum, verify the nameplate and terminals, inspect for overheating or capacitor damage, measure the output under controlled conditions, and perform a meaningful load test. A no-load voltage check alone is not sufficient evidence for a 60 A system power supply.
Procurement Note
For Metso Automation procurement, verify these points before issuing a purchase order:
- Full part number:
- Product identification: SPUC Power Unit Module
- Input: 100–240 VAC
- Frequency: 45–65 Hz
- Maximum output: 60 A
- Reported DC output: approximately 18–27.2 VDC
- Existing Metso Automation system/platform
- Hardware revision and nameplate details
- Condition: new surplus, unused, refurbished, or used
- Functional test evidence for refurbished equipment
- Terminal and mechanical compatibility
- Whether the proposed replacement is an original rather than an unverified substitute
The most important point is simple: do not substitute a generic 24 VDC supply merely because its nominal voltage looks correct. The is a high-current system power component, and the installed Metso architecture determines whether another supply can actually perform the same job.
Because the is documented as discontinued, maintaining a tested spare can be particularly important for plants running legacy Metso Automation control systems.
