KIKUSUI Equipment We Repair — By Category
KIKUSUI Product Lines We Repair
Our engineers are trained on the full KIKUSUI product range. Below are the major product families we service.
PAC Series Programmable AC Power Supplies
Kikusui PAC series delivers variable frequency AC output (45-5000 Hz) with programmable voltage and phase control. Common failures include internal transformer faults, thyristor failures in the converter stage, and DSP board malfunctions causing output instability.
PLZ Series Electronic DC Loads
PLZ series programmable electronic loads simulate real-world power consumption for power supply testing and battery characterization. Typical faults include transistor array burnout, analogue control circuit failures, and measurement ADC errors affecting load accuracy.
PMC Series Programmable DC Power Supplies
PMC series combines regulated DC output with high current capacity for R&D, manufacturing test, and system integration applications. Frequent issues include capacitor bank degradation, feedback reference circuit drift, and power transistor gate-drive failures.
KPA Series High-Frequency Power Amplifiers
KPA series extends Kikusui's range into RF and audio amplification for telecom and broadcast equipment testing. Common repair needs include RF amplifier tube wear, impedance matching circuit failures, and cooling fan bearing degradation.
TEC Series Temperature Environmental Chambers
TEC series integrates with Kikusui power supplies for accelerated life testing in controlled thermal conditions. Faults typically involve temperature sensor calibration drift, relay contactors sticking, and refrigerant circuit leaks.
KFG Series Function Generators
KFG series precision signal generators provide programmable waveforms for equipment validation and signal injection testing. Repair issues include DAC non-linearity, phase-locked-loop lock failures, and output amplifier clipping.

Common KIKUSUI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in KIKUSUI equipment arriving at our workshop.
- ✓PAC series output voltage unstable or oscillates — Thyristor commutation circuit in the AC converter stage fails due to gate-drive transformer winding short or dV/dT triggering. Control DSP board may also lose phase synchronization with input AC mains.
- ✓PLZ electronic load draws zero current or maximum current — Transistor array in the load dissipation stage suffers thermal runaway and shorts, or control feedback fails due to ADC sampling error in the measurement circuit. Burnt PCB traces are common secondary damage.
- ✓PMC power supply output voltage drifts or lags setpoint — Electrolytic output filter capacitors age and lose capacitance, or the error amplifier reference circuit develops a bias offset due to temperature drift in precision resistors. Feedback divider network corrosion is also seen in humid Indian environments.
- ✓KPA amplifier RF output power drops below rated specification — Output amplifier tubes age and lose emission, or impedance matching network capacitors develop ESR and degrade load impedance matching. Cooling fan bearing wear reduces heat dissipation, causing thermal derating.
- ✓TEC chamber temperature overshoots or oscillates around setpoint — Temperature sensor (thermocouple or RTD) develops drift due to mechanical vibration or contaminant buildup inside the probe pocket. Proportional-integral control loop gain settings become mistuned after sensor replacement.
- ✓KFG function generator output amplitude distorts or contains noise — DAC (digital-to-analogue converter) suffers bit-slip or code transition glitches, or output amplifier feedback network coupling capacitors degrade. Phase-locked-loop jitter increases due to noisy crystal oscillator.

Frequently Asked Questions — KIKUSUI Repairs
Do you repair Kikusui equipment anywhere in India?+
Yes. Synchronics repairs the complete Kikusui product range — PAC programmable AC supplies, PMC DC supplies, PLZ electronic loads, KPA RF amplifiers, TEC environmental chambers, and KFG function generators. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all tier-1 and tier-2 cities. All repairs are completed at our certified facility in Vadodara, Gujarat.
What is the typical turnaround time for Kikusui PAC power supply repair?+
Most Kikusui PAC series repairs complete within 5-7 working days. Diagnosis and component testing (thyristor, gate-drive transformer, DSP board) takes 1-2 days. Component replacement and full-load stability testing takes another 2-3 days. If custom calibration or burn-in testing is required, we add 2-3 additional days. Synchronics provides daily repair status updates via email and phone.
Can Synchronics calibrate Kikusui electronic loads to current industry standards?+
Yes. After repair of Kikusui PLZ series loads, Synchronics performs full calibration traceable to NIST standards. We verify current accuracy across 10%-100% load range, measure output impedance, and validate dynamic load transient response. Our calibration certificate includes test data and uncertainty specifications, required for regulated manufacturing sectors like medical devices and aerospace.
Why does my Kikusui PMC power supply lose regulation when switching loads rapidly?+
Rapid load transients stress the feedback control loop in Kikusui PMC supplies. If output impedance increases due to aged filter capacitors or corroded PCB traces, the feedback amplifier cannot respond fast enough. Synchronics replaces electrolytic capacitors, cleans PCB corrosion, and optimizes feedback divider resistor networks. We then test transient response with step-change loads to confirm recovery time meets specification.
Does Kikusui equipment need recalibration after repair?+
Yes, recommended for all Kikusui test and measurement equipment — PAC/PMC power supplies, PLZ electronic loads, KFG function generators. Synchronics includes baseline recalibration with every repair, measuring output voltage, current, frequency, and measurement accuracy. For accredited manufacturing environments, we provide ISO 9001 calibration certificates with traceability records.
How do I send my KIKUSUI unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a KIKUSUI drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on KIKUSUI repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your KIKUSUI unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
