Frequently Asked Questions:

ABB DSSR116 Power Supply Module

1. General Product Information
Q: What is the primary function of the ABB DSSR116, and which systems is it compatible with? 

A: The DSSR116 is a high-performance DC/DC Power Supply Unit designed for ABB’s legacy automation platforms. It is primarily used in:

Advant Controller 400 (AC400) series.

MasterPiece 200 (MP200) systems. It converts raw DC input into the stabilized, regulated voltages required by internal bus modules and processor boards.

2. Condition & Quality Assurance
Q: Do you provide Brand New or Refurbished DSSR116 modules? 

How do you ensure quality? A: We offer various conditions to meet your specific needs:

New in Box (NIB): Original factory-sealed units with authentic labels.

Refurbished: Professionally cleaned and inspected units that have undergone a 100% Full-Load Test.

Quality Commitment: Every unit is tested on a dedicated ABB test rig before shipping. We provide a Test Report or video confirmation upon request to ensure "Plug-and-Play" reliability.

3. Lifecycle & Obsolescence
Q: Has the ABB DSSR116 been discontinued? What should I do if it's out of stock?

 A: Yes, the DSSR116 is currently in the Limited/Obsolete phase of the ABB product lifecycle.

Our Solution: We maintain a large inventory of discontinued parts to minimize your downtime.

4. Troubleshooting & Maintenance
Q: What does a fault light on the DSSR116 module indicate? 

A: A fault LED usually points to one of the following issues:

Input Voltage Fluctuation: The input power is outside the specified range.

Capacitor Aging: Internal electrolytic capacitors may have failed due to long-term operation, causing high ripple voltage.

Overload Protection: A short circuit or excessive load on the backplane may trigger an automatic shutdown.

We offer professional repair services and "Exchange Programs" for faulty modules.
