Chroma 63110A DC Load Repair and Calibration
The Chroma 63110A is a programmable DC electronic load — it sinks programmable current and power to test power supplies, batteries, and sources, operating in constant-current, constant-voltage, constant-resistance, and constant-power modes. Its character is precise high-current sinking with fast dynamic response, so faults concentrate in the load (sink) stage, the mode-control circuitry, and measurement.
June Company repairs and calibrates the Chroma 63110A for power-supply and battery test teams.
Common Chroma 63110A problems we fix
- Won’t sink rated current — load-stage (power MOSFET) failure, the defining DC-load fault, repaired so it sinks full rated current and power.
- A mode (CC/CV/CR/CP) not working — mode-control circuitry faults, repaired and verified.
- Dynamic/transient response off — the fast-slew circuitry, restored.
- Readback inaccurate — voltage/current measurement drift, recalibrated.
- Programming or fan faults.
FAQs
My load won’t pull rated 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 the load 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.

Shipping & Returns
Packing your equipment. You are responsible for packaging equipment adequately for transit. We strongly recommend the original manufacturer’s case, or double-boxing with at least two inches of shock-absorbing material on all six sides. We return your equipment in the packaging it arrived in, so please send it in packaging that will survive the return trip as well. If your packaging is damaged or inadequate for the return, we will substitute suitable packaging and may charge the cost of materials.
Insurance. Equipment is not insured by June Company while in transit. We strongly recommend insuring your shipment for its full replacement value.
Risk of loss. Risk of loss remains with you until your equipment is received at our facility, and transfers back to you when your repaired unit is delivered to the carrier (F.O.B. shipping point). June Company is not responsible for equipment lost, delayed, misdelivered, or damaged in transit, in either direction.
Return label. A prepaid and preprinted return shipping label should be included with your shipment. If one is not included, we will provide one.
Transit damage. Damage occurring in transit is the responsibility of the carrier. It is not a warranty defect and is not covered by the 90-day repair warranty. Any claim must be filed by you with the carrier; we will supply photographs and documentation to support it at no charge.
