CONZERV Product Lines We Repair
Our engineers are trained on the full CONZERV product range. Below are the major product families we service.
Active Harmonic Filters (AHF)
Real-time harmonic mitigation devices that inject compensating currents to neutralize non-linear load distortion. Common failures include IGBT module burnout, DC bus capacitor degradation, and loss of current feedback from CT sensors in harsh industrial environments.
Automatic Power Factor Correction (APFC) Panels
Microprocessor-controlled power factor correction units with stepped capacitor bank switching. Typical faults involve contactor weld-through, capacitor rupture due to inrush current, relay logic failure, and ammeter/voltmeter sensor errors in control circuits.
Energy Management & Monitoring Units
Three-phase power analyzers and energy loggers with Modbus RTU/TCP connectivity. Issues include LCD panel dead segments, RS-485 transceiver failure, real-time clock battery depletion, and corrupted EEPROM preventing parameter retention.
Thyristor-Switched Capacitor (TSC) Modules
Fast-acting reactive power modules using thyristor pairs and snubber circuits. Failures stem from thyristor leakage current in high-temperature industrial settings, snubber resistor open circuits, gate drive power supply collapse, and gate pulse loss.
Harmonic & Power Quality Analyzers
Portable and fixed-mount power quality audit equipment measuring Total Harmonic Distortion (THD), voltage imbalance, flicker, and interharmonics. Common defects include current clamp sensor failure, battery pack degradation, USB interface chip failure, and software crashes during harmonic scan mode.
Reactive Load Banks & Dummy Loads
Precision resistive and inductive load banks for testing APFC and harmonic filter response. Failures include heater coil insulation breakdown, fan motor bearing seizure, thermostat contact fusion, and relay logic card damage from high voltage transients.

Common CONZERV Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CONZERV equipment arriving at our workshop.
- ✓APFC panel contactor chattering no power — Insufficient coil voltage due to low mains voltage or series impedance dropout. Mechanical wear on contactor plunger creates incomplete armature engagement. Auxiliary switch contact corrosion prevents microprocessor coil re-energization feedback.
- ✓AHF shows zero harmonic compensation current — Open-circuit in current transformer (CT) secondary winding or loose terminal connections feeding the feedback signal to the AHF microcontroller. IGBT driver optocoupler failure prevents gate signal generation. ADC input channel failure on DSP board prevents current feedback measurement.
- ✓Capacitor bank rupture tripping main breaker — Inrush transient current exceeding capacitor voltage rating due to synchronous or near-synchronous switching. Weakened capacitor case from prior thermal stress allows internal corona discharge to propagate. Failing detuning reactor allows harmonic resonance, causing overvoltage across capacitor terminals.
- ✓EMU power analyzer LCD frozen dead segments — LCD contrast voltage driver failure or internal segment driver IC reset due to ESD or mains transient. Corrosion on LCD flex connector reduces signal integrity. Corrupted firmware in microcontroller locks display refresh routine.
- ✓TSC module thyristor conducts continuously no switching — Gate drive power supply rails collapsed below minimum operating voltage. Gate drive optocoupler failed preventing pulse transmission. Thyristor short-circuit due to overvoltage stress or repeated switching transients. Snubber capacitor open circuit or resistor burnt out.
- ✓Power quality analyzer USB port unrecognized communication — USB interface chip (often FT232 or CP2102 variant) fails due to overvoltage on data lines. USB connector pin corrosion or cold solder joint breaks signal path. Firmware bootloader corrupted preventing USB device enumeration during host PC discovery.

Frequently Asked Questions — CONZERV Repairs
Do you repair CONZERV equipment anywhere in India?+
Yes. Synchronics repairs the complete CONZERV product portfolio — Active Harmonic Filters, APFC panels, energy monitors, TSC modules, and power quality analyzers. We offer PAN-India door-step pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Bangalore, and all other metros. All repairs are performed in our Vadodara headquarters with same-day diagnostics and expedited turnaround to minimize production loss.
What is the typical repair cost for a CONZERV APFC panel capacitor replacement?+
Capacitor replacement cost depends on the kVAR rating and number of failed units. A single 50kVAR APFC panel costs Rs 8,000-15,000 including testing, capacitor sourcing, and re-commissioning. Multi-stage panel repairs (e.g., 200kVAR units with 4-8 capacitor stages) range from Rs 25,000-40,000. Synchronics provides upfront quotations after on-site audit and offers extended warranties on all replaced capacitor banks.
How long does CONZERV Active Harmonic Filter repair typically take?+
Standard AHF repairs (optocoupler, relay, or driver IC replacement) complete in 2-3 working days. IGBT module replacement or DC bus capacitor bank rebuild extends turnaround to 4-5 days. Critical site repairs can be expedited to 24-48 hours if shipped with premium courier. Synchronics maintains on-site spare IGBT modules, optocouplers, and power supply components to reduce waiting times for industrial clients.
Can CONZERV harmonic filter firmware be reprogrammed if corrupted?+
Yes. If a CONZERV AHF or APFC controller microprocessor becomes corrupted (missing harmonic compensation, incorrect switching frequency, or frozen display), Synchronics can reprogram the flash memory using JTAG or ISP interfaces. We maintain verified firmware images for all CONZERV product families and can restore original calibration parameters. Post-reprogramming, we perform full-load harmonic injection testing to confirm algorithm recovery.
What warranty do you provide on CONZERV repairs at Synchronics?+
All CONZERV repairs carry a standard 12-month parts and labor warranty covering defects in Synchronics workmanship and component failures. Extended 24-month warranties are available on capacitor bank replacements and IGBT modules. If equipment fails during warranty, Synchronics will repair or replace the component free of charge. Warranty excludes damage from customer misuse, incorrect installation, or exceeding rated electrical specifications.
How do I send my CONZERV 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 CONZERV 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 CONZERV 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 CONZERV 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.
