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.

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.
