Chroma 63630-80-60 DC Load Repair and Calibration
The Chroma 63630-80-60 DC Load is a programmable DC electronic load. It sinks a set current, voltage, resistance or power from a supply or battery under test, so the source can be characterized without a bank of resistors. If its sink stage or metering drifts, the efficiency and regulation figures taken with it are wrong.
June Company repairs and calibrates the Chroma 63630-80-60 DC Load for power-supply and battery test labs, production test departments, and design engineers. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
Common Chroma 63630-80-60 DC Load problems we fix
- Load current not reaching setpoint or unstable.
- Constant-voltage, resistance or power modes out of regulation.
- Voltage or current readback out of tolerance.
- MOSFET sink-stage failure.
- Overpower or overtemperature protection tripping early.
- Dynamic (transient) mode timing errors.
- Cooling fan or thermal faults.
- Display, keypad or front-panel faults.
- GPIB, LAN, USB or remote-control faults – which breaks automated test sequences while the instrument still works from the front panel.
FAQs
One channel reads differently from the rest. Can you repair just that channel? Yes. We repair at component level and calibrate every channel, so the set reads consistently when it comes back.
What if it is not economical to repair? We tell you in the quote, and you decide whether to go ahead.
Every repair carries a 90-day parts-and-labor warranty, with a firm quote before any work begins. Email us or submit a service request.
