Chroma 63800R Electronic Load Repair
The Chroma 63800R is a regenerative AC & DC electronic load — it sinks AC and DC current (with programmable power factor and crest factor) while returning the absorbed energy to the grid, used to test AC sources, UPS systems, inverters, and power supplies efficiently. Its character is regenerative AC-capable current sinking, so faults concentrate in the load stage, the regenerative/PF control, and measurement.
June Company repairs and calibrates the Chroma 63800R for AC-source, UPS, and inverter test teams.
Common Chroma 63800R problems we fix
- Constant-current / CC-mode faults — the CC loading not regulating correctly, repaired and verified.
- Won’t sink rated AC/DC current — load-stage failure, repaired so it sinks full rated load.
- Regenerative / bidirectional faults — the power electronics that return energy, repaired.
- Power-factor / crest-factor control faults — the AC-loading control, repaired.
- Readback inaccurate — measurement drift, recalibrated.
FAQs
My 63800R won’t load in CC or regenerate correctly — fixable? Yes. Load-stage and regenerative-control faults are repairable, then verified so it loads with correct CC/PF and returns energy, with a NIST-traceable certificate.
Is AC and DC loading verified? Yes — both 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.
