Technical Specifications

Note: Electrical parameters specific to this board sub-assembly are not published in Schneider Electric's public documentation. DriveKNMS does not fabricate specifications. All technical verification is performed during our QA process prior to shipment.

Solving the Discontinued Hardware Crisis

The ATS48 soft starter platform was a workhorse of industrial motor control for over two decades. It was deployed in water treatment facilities, oil and gas compression stations, mining conveyors, and HVAC systems across every major industrial market. Schneider Electric has since migrated its soft starter portfolio to the Altistart 48 successor lines and the ATS480 series, but the installed base of ATS48 units remains substantial.

The power supply board — reference 16250850112A08 — is the internal component responsible for providing regulated DC voltage to the control logic and gate drive circuitry of the soft starter. Without a functioning power supply board, the entire soft starter is inoperable. There is no field repair path for a failed board of this type; replacement is the only viable corrective action.

For plant managers operating facilities where ATS48 soft starters are integrated into process-critical motor control loops, the calculus is straightforward. A single unplanned shutdown on a pump or compressor driven by an ATS48 unit can cost more in lost production per day than the entire cost of maintaining a spare board inventory for five years. The argument for proactive spare parts management is not theoretical — it is a direct cost-avoidance measure.

Extending the operational life of an ATS48 installation by 5 to 10 years through targeted spare parts procurement is a documented strategy used by maintenance engineering teams in process industries. The approach requires identifying the highest-failure-risk sub-assemblies — power supply boards, gate drive boards, and control interface cards — and securing verified replacements before failure occurs. DriveKNMS specializes in sourcing exactly these components from the secondary market, applying rigorous inspection protocols before any unit leaves our facility.

Condition & Reliability Assurance

Every ATS48C 16250850112A08 board processed by DriveKNMS passes a five-stage inspection protocol before it is offered for sale. This process was developed specifically for obsolete industrial electronics where age-related degradation is the primary failure risk.

Stage 1 – Visual and Physical Inspection: Full board examination for mechanical damage, burn marks, cracked solder joints, and corrosion on connector pins and PCB traces.

Stage 2 – Electrolytic Capacitor Assessment: Electrolytic capacitors are the component most likely to degrade with age on power supply boards of this era. Each capacitor is checked for bulging, leakage, and ESR (equivalent series resistance) drift. Capacitors outside specification are replaced with equivalent-rated components.

Stage 3 – Firmware and Configuration Verification: Where applicable, onboard firmware versions are confirmed against known-good references for the ATS48 platform to ensure compatibility with the target soft starter unit.

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

Stage 5 – Functional Power-On Test: The board is subjected to a controlled power-on test to verify that regulated output voltages are within specification before packaging.

Key Features for System Maintenance

The ATS48C 16250850112A08 is a direct drop-in replacement for the original board installed in compatible ATS48 soft starter frames. Installation does not require reprogramming of the soft starter's parameter set, reconfiguration of the control wiring, or any modification to the motor control center in which the unit is installed. This is a board-level swap — remove the failed board, install the replacement, restore power.

Q: How is condition confirmed before quotation?
A: Available condition, photos, test records and documentation are checked according to the requested model and sourcing channel before a formal RFQ response.

How do I confirm the unit is new or professionally refurbished — not a field-pulled scrap part?
Every unit sold by DriveKNMS is accompanied by an inspection report documenting the five-stage QA process described above. We do not sell untested field-pull units. If you require photographic documentation of the specific unit prior to purchase, we provide this on request.

Q: Can you support multi-unit or repeat RFQ requests?
A: Yes. Send the model list, target quantity and destination so DRIVEKNMS can review sourcing options and quote the requirement as a project RFQ.

Can you source other ATS48 sub-assemblies?
Yes. DriveKNMS maintains sourcing networks for the broader ATS48 spare parts ecosystem, including gate drive boards, control interface cards, and keypad assemblies. Contact us with your specific part references.
