The Metso A413337 is a SPUC Power Unit Module designed for Metso Automation industrial control systems. It functions as a high-capacity power supply unit, converting the incoming AC power into regulated DC power required by the control system and connected automation equipment.
The A413337 is specified for a 100–240 VAC input, 45–65 Hz frequency range, and a maximum output current of 60 A. Available product records identify the unit as a Metso Automation SPUC power supply and indicate an output range of approximately 18–27.2 VDC.
The model is also associated with older Metso Automation control-system installations and is currently listed as discontinued by the manufacturer, making reliable replacement sourcing particularly important for plants maintaining legacy automation equipment.

What Is the Metso A413337?
The A413337 is part of the Metso Automation SPUC power supply family.
In an industrial control system, the power supply is responsible for providing stable DC power to control electronics, I/O assemblies, communication equipment, and other system components. A failure of the power supply can therefore affect multiple parts of the automation system simultaneously.
The A413337 accepts a wide AC input range of 100–240 VAC, allowing it to operate across different industrial power environments. Its high-current DC output makes it suitable for systems with substantial power requirements.
A simplified power architecture can be represented as:
AC Input → Metso A413337 SPUC Power Unit → Regulated DC Bus → Control System / I/O / Automation Equipment
Because the A413337 is part of the system power infrastructure, it is generally treated as a critical maintenance spare rather than an ordinary electronic accessory.
Key Functions of A413337
1. AC-to-DC Power Conversion
The primary function of the A413337 is to convert the incoming AC supply into DC power suitable for the associated Metso Automation system.
The specified input range is:
100–240 VAC / 45–65 Hz
This broad input range allows the power unit to operate with common industrial AC supply configurations.
2. High-Current DC Output
The A413337 is designed for a maximum output current of approximately 60 A.
This makes it substantially different from small auxiliary power supplies used for individual sensors or low-power control circuits.
Its role is better understood as a system-level power unit, supplying the DC power required by a larger automation installation.
3. Stable Power for Automation Equipment
Industrial controllers and I/O systems require a stable power source. Voltage fluctuations or an overloaded power supply can result in:
- Controller resets
- I/O communication interruptions
- Module faults
- Unexpected system shutdowns
- Loss of process monitoring
- Production downtime
The A413337 therefore forms an important part of the electrical infrastructure supporting the control system.
4. Legacy System Support
The A413337 is particularly relevant to plants operating older Metso Automation systems.
Although the manufacturer has discontinued the part, existing installations may continue operating for many years. This creates a demand for replacement, refurbished, and tested units when the original power supply reaches the end of its service life.
Technical Specifications
| Parameter | Specification |
| Model | A413337 |
| Product Family | SPUC |
| Product Type | Power Unit / Power Supply |
| Input Voltage | 100–240 VAC |
| Input Frequency | 45–65 Hz |

| Input Current | Approx. 1 A Max. |
| System Manufacturer | Metso Automation |
| Mounting | Industrial control-system installation |
| Approx. Net Weight | 6–7 kg |
| Manufacturer Status | Discontinued |
The published electrical specifications consistently identify A413337 as a 60 A power supply with 100–240 VAC input and 45–65 Hz frequency. A separate listing specifies the DC output as approximately 18–27.2 VDC.
Understanding the SPUC Power Unit
The term SPUC is commonly used in listings for the A413337 and identifies the power-unit configuration.
The A413337 should therefore be searched and sourced using several identifiers rather than the part number alone:
Metso A413337
Metso Automation A413337
SPUC A413337
Metso SPUC Power Unit
A413337 Power Supply
Using these identifiers can help locate compatible maintenance stock, especially when working with older Metso Automation installations.
A413337 in a Metso Automation Control System
A typical power architecture can be represented as:
Plant AC Power
↓
A413337 SPUC Power Unit
↓
DC Power Distribution
↓
Metso Automation Control Hardware
↓
Controllers / I/O / Communication / Field Interface
The power supply therefore sits upstream of many electronic components.
This is why a failed A413337 can cause symptoms that initially appear to be unrelated controller or I/O problems. If multiple modules lose power simultaneously, maintenance engineers should consider the system power supply and its distribution circuit before replacing individual control modules.
Typical Applications
The Metso A413337 can be found in industrial automation installations where Metso Automation control equipment requires high-capacity DC power.
Typical applications include:
- Pulp and Paper Plants
Metso has a strong presence in pulp and paper automation, where reliable control-system power is essential for continuous production. - Process Automation
The power unit can support control-system electronics and distributed automation hardware. - Industrial Manufacturing
Suitable for legacy Metso Automation control installations requiring high-current DC power. - Continuous-Process Industries
Reliable power is particularly important where an automation-system shutdown can interrupt an entire production line. - Metso Legacy Control Systems
Particularly relevant for maintenance and replacement of older installations where the original A413337 is no longer manufactured.
Why the A413337 Is Important as a Spare Part
Power supply failures can have a much larger impact than the failure of a single I/O point.
A defective system power supply may cause:
- Multiple modules to shut down
- Controller communication loss
- I/O station failure
- System alarms
- Unplanned process interruption
- Difficult-to-diagnose intermittent faults
For this reason, maintaining a spare A413337 can reduce recovery time when a legacy Metso control system experiences a power-related failure.
This is especially relevant because A413337 is currently identified as discontinued, meaning that replacement procurement may depend on remaining new-old-stock, unused inventory, refurbished units, or tested surplus stock.
A413337 vs. A413331
The A413331 and A413337 are both associated with Metso Automation power units, but they should not be considered direct substitutes without checking the system requirements.
| Feature | A413331 | A413337 |
| Product Family | Metso Automation Power Unit | Metso Automation SPUC |
| Part Number | A413331 | A413337 |
| Function | Power Unit | SPUC Power Unit |
| Output Rating | Different configuration | 60 A Max. |
| Replacement | System-dependent | System-dependent |
Some supplier references describe A413331 as a 35 A SPU power unit, while A413337 is identified as a 60 A SPUC power supply. Therefore, replacing one with the other requires confirmation of the original system design and electrical requirements.
Maintenance and Replacement Considerations
When replacing an A413337, it is important to verify the complete electrical specification instead of selecting a power supply based only on output voltage.
Recommended checks include:
- Part Number
Confirm that the original unit is A413337. - Input Voltage
Verify the system’s AC supply is within the 100–240 VAC range. - Frequency
Confirm the incoming supply is compatible with the 45–65 Hz specification. - Output Voltage
Verify the required DC bus voltage before installation. - Output Current
Confirm that the replacement can support the system’s required current, up to the specified 60 A capacity. - Connector and Mechanical Configuration
Check the physical mounting and electrical connections against the installed unit. - Condition
For discontinued equipment, distinguish carefully between new old stock, unused surplus, refurbished, and used units. - Testing
For refurbished equipment, request power-on and load testing where available.
Inspection Points for Used or Refurbished A413337
Because A413337 is a discontinued industrial power supply, used and refurbished units may appear on the market.
Before purchasing a used unit, inspect:
- Housing condition
- Power terminals
- Connector condition
- Cooling and ventilation areas
- Signs of overheating
- Capacitor leakage or swelling
- Burn marks or discoloration
- Label and part-number readability
- Output-voltage stability
- Performance under load
For critical process equipment, functional testing is strongly recommended before the replacement unit is placed into service.
