Chroma 61800-100 Grid Simulator Repair and Calibration
The Chroma 61800-100 is a regenerative grid simulator — a bidirectional AC source that generates programmable grid conditions (voltage, frequency, phase, harmonics, faults/anomalies) and can absorb energy, to test grid-tied inverters, EV chargers, and renewable-energy equipment to standards. As a high-power regenerative AC source, its faults concentrate in the output power stage, the regenerative/control electronics, waveform generation, and measurement — not the hipot faults its category label implies.
June Company repairs and calibrates the Chroma 61800-100 for grid-tied inverter, EV-charger, and renewable-energy test teams.
Common Chroma 61800-100 problems we fix
- No output or won’t reach setpoint — AC output power-stage failure, repaired so it sources full programmed grid conditions.
- Regenerative / bidirectional faults — the power electronics that absorb energy, repaired.
- Waveform / fault-simulation faults — the programmable grid-anomaly generation not producing correct output, repaired.
- Measurement off — the built-in metering drifting, recalibrated against standards.
- Cooling, protection, or interface faults.
FAQs
My 61800-100 won’t generate correct grid conditions — fixable? Yes. Output power-stage and control faults are repairable, then verified so it sources and absorbs correct programmed grid conditions, with a NIST-traceable certificate.
Is the measurement verified? Yes — output and metering 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.
