Description

Keithley 2290 Power Supply Repair

The Keithley 2290 is a high-voltage DC power supply — a precision bench supply (the 2290-5 sources up to 5 kV, the 2290-10 up to 10 kV) used to bias detectors, photomultipliers, and components in research and test. High-voltage output sets its fault profile apart from low-voltage supplies: the HV multiplier, regulation, and insulation take the stress.

June Company repairs and calibrates the Keithley 2290 for research labs and test engineers.

Common Keithley 2290 problems we fix

Won’t reach rated kV or output collapses — HV multiplier/output-stage failure, rebuilt for full rated output.
Output unstable or won’t regulate — regulation-loop degradation, recalibrated for stable HV.
Voltage/current readback inaccurate — measurement drift, recalibrated against standards.
Internal HV arcing or leakage — insulation breakdown from stress.
Programming or control faults — restored.

FAQs

My 2290 HV output is low or unstable — fixable? Yes. HV multiplier and regulation faults are serviceable; we restore full stable rated output and recalibrate, with a NIST-traceable certificate.

Is the readback verified? Yes — voltage and current readback 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.
