Chroma 63207 DC Load Repair and Calibration
The Chroma 63207 is a programmable DC electronic load module — a higher-power member of the 63200 modular load family that sinks programmable current and power to test power supplies, batteries, and chargers in CC, CV, CR, and CP modes. Its character is high-current sinking, so faults concentrate in the load (sink) stage, mode control, and measurement — not the hipot/HV faults its category label implies.
June Company repairs and calibrates the Chroma 63207 for power-supply and battery test teams.
Common Chroma 63207 problems we fix
- Won’t sink rated current/power — load-stage (power MOSFET) failure, repaired so it sinks full rated load.
- A mode (CC/CV/CR/CP) not working — mode-control faults, repaired.
- Dynamic/transient response off — the fast-slew circuitry, restored.
- Readback inaccurate — measurement drift, recalibrated.
- Programming or cooling faults.
FAQs
My 63207 won’t pull full current — fixable? Yes. Load-stage faults are repairable, then verified so it sinks full rated current and power in every mode, with a NIST-traceable certificate.
Are all modes verified? Yes — CC, CV, CR, and CP are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
