Triconex 3002 | Power Supply Module, In Stock, Fast Shipping

Description

Product Introduction

The Triconex 3002 is a power supply module designed for the Tricon Triple Modular Redundant (TMR) safety system. This module provides regulated 24 V DC power to the Tricon main chassis, supplying the controller, I/O modules, and backplane electronics. The 3002 mounts in the dedicated power supply slots of the Tricon main chassis and supports a triple-redundant configuration, ensuring continuous operation even if one or two power supplies fail.

The Triconex Tricon platform is one of the most widely deployed safety instrumented systems (SIS) in the world, with thousands of installations in oil and gas, refining, chemical, and power generation facilities. The 3002 is the standard power supply for Tricon main chassis. Redundancy is built into the architecture—Tricon chassis are designed to accept up to three 3002 power supplies, with each supply providing one-third of the total power and automatic failover. For facilities operating Tricon systems, sourcing verified 3002 power supplies is essential for maintaining the high availability that the TMR architecture is designed to provide.

Key Technical Specifications

Key Selling Points & Differentiators

• Triple Redundant Architecture: Tricon chassis accepts up to three 3002 power supplies. If one supply fails, the remaining supplies continue to provide full power to the system without interruption.
• Hot-Swap Capability: Replace a failed power supply without powering down the Tricon chassis. The redundant supplies maintain system power during the swap.
• Legacy System Support: Direct replacement for original Triconex 3002 power supplies in Tricon main chassis. No configuration changes required when replacing with the same part number.
• Comprehensive Protection: Overcurrent, overvoltage, short-circuit, and overtemperature protection ensure the power supply does not damage the Tricon chassis or cause unsafe conditions.
• Authenticity Guarantee: Each unit undergoes visual inspection for Triconex OEM markings, serial number traceability, and PCB integrity. We test every power supply under load before shipping.

Frequently Asked Questions (FAQ)

Q: Which Tricon chassis is the 3002 compatible with?
The 3002 is compatible with all Tricon main chassis, including:

• Tricon v9 and v10 main chassis
• Tricon 3000 series main chassis

It is not compatible with the Tricon CX chassis or Tricon 4000 series, which use different power supply modules. Verify your chassis model before ordering.

Q: Is this power supply discontinued?
Yes. Triconex has transitioned to newer power supply modules for the Tricon CX and other platforms. The 3002 is no longer in active production. Availability is limited to new surplus and tested used inventory. For Tricon systems still in operation, we recommend securing spares while stock remains available.

Q: How many power supplies do I need for my Tricon chassis?
Tricon chassis can be configured with one, two, or three power supplies:

• Single supply: Provides basic power with no redundancy
• Two supplies: Provides redundancy but requires both supplies to handle the full load
• Three supplies: Triple redundancy—the chassis can lose up to two supplies and still operate normally

For critical safety applications, we recommend three supplies to maintain the TMR architecture at all levels.

Q: Can I mix the 3002 with other Triconex power supplies?
No. The Tricon main chassis is designed to use identical power supply modules. If your chassis currently uses 3002 modules, replacements must also be 3002. Mixing different models or revisions may result in improper load sharing or communication with the chassis backplane.

Q: Can I hot-swap the 3002 in a running Tricon system?
Yes, but only if the chassis is configured with redundant power supplies. In a system with two or three supplies, you can remove and replace one supply while the system remains powered. In a single-supply configuration, the chassis must be powered down before replacement.

Q: What are common failure modes for this power supply?
In our experience, the most common failures are:

• Capacitor aging causing output ripple or voltage drift
• Input fuse failure due to power surges
• Fan failure (if equipped; some revisions have internal cooling fans)
• Connector corrosion in high-humidity environments

We recommend testing output voltages periodically during scheduled outages and keeping spares on hand.

Q: What testing do you perform before shipping?
We test every 3002 under load before shipping. Our test procedure includes:

• Visual inspection for physical damage, corrosion, or previous repairs
• Input voltage tolerance testing (90 to 264 V AC)
• Output voltage verification under load (24 V DC)
• Ripple and noise measurement
• Hold-up time verification
• 24-hour continuous power-on soak test

A test report with measured output voltage and load test results is included with each shipment.
