ABB PFSK 101 Power Supply Unit – ADVANT Controller 450 Series
When a power supply module fails inside a running ADVANT Controller 450 system, the consequences are immediate and severe: the entire DCS node loses regulated voltage, I/O racks go dark, and the process control loop drops to manual — or worse, to an uncontrolled state. In continuous-process industries such as pulp & paper, oil & gas, and chemical manufacturing, even a 15-minute unplanned shutdown can cost tens of thousands of dollars in lost production and emergency labor. The ABB PFSK 101 is the dedicated power supply backbone that prevents this scenario, delivering stable, conditioned DC power to every board and backplane in the AC450 cabinet.
Within the ADVANT Controller 450 family, the PFSK 101 occupies the role of primary power distribution module. It accepts the incoming DC bus from the system power supply and conditions it into the precise voltage rails required by the processor, communication, and I/O sub-modules. As part of ABB’s globally deployed ADVANT automation platform — installed in thousands of facilities across more than 100 countries — the PFSK 101 represents a mature, field-proven design with a long service history in mission-critical environments.

Frequently Asked Questions
Q: Is the ABB PFSK 101 still in production?
A: The PFSK 101 is a legacy module from ABB’s ADVANT Controller 450 series, which has reached end-of-life status with the OEM. Konmask.com specializes in sourcing tested surplus and refurbished stock to support ongoing plant operations.
Q: What is the difference between new surplus and refurbished?
A: New surplus units are unused modules from original production runs, stored in controlled conditions. Refurbished units have been previously installed, then cleaned, inspected, and functionally tested by our technicians. Both are clearly labeled in our quotations.
Q: Can you supply a Certificate of Conformance (CoC)?
A: Yes. A CoC and inspection report are available for tested refurbished units. Please request this at the time of inquiry.
Q: How long does shipping take?
A: Express courier (DHL/FedEx/UPS) typically delivers within 3–7 business days internationally, depending on destination and customs clearance. We provide tracking numbers upon dispatch.
Q: Do you accept returns?
A: Yes, within the warranty period and subject to our returns policy. Please contact [email protected] to initiate a return authorization.
