ELECTROSISTEM Product Lines We Repair
Our engineers are trained on the full ELECTROSISTEM product range. Below are the major product families we service.
EDS-UPS Range
Electrosistem's advanced online and line-interactive UPS systems for critical power backup. Common repairs involve battery charger faults, inverter IGBT failures, sensing circuit drift, and static bypass contactor wear affecting load transfer speed.
SVC-PRO (Static VAR Compensator)
Thyristor-switched reactive power control for voltage stabilization in mills and manufacturing plants. Typical faults include thyristor gate drive circuit failures, reactor winding insulation breakdown, and harmonic distortion measurement errors in control firmware.
HFC-Active (Harmonic Filter Controller)
Active harmonic filtering system reducing THD in plants with heavy non-linear loads. Repairs focus on current sensor calibration drift, PWM inverter gate driver failures, and digital signal processor firmware corruption affecting harmonic compensation algorithms.
ESSC-Soft Starters
Electronic soft starting controllers for AC induction motors reducing mechanical stress and inrush current. Common issues include thyristor phase control circuit faults, temperature sensor malfunction, and communication protocol errors in networked units.
RPC-Series (Reactive Power Controller)
Microprocessor-based power factor correction and voltage regulation for distribution-level industrial networks. Repairs address capacitor bank contactor failures, analog input signal conditioning errors, and PLC logic board memory degradation.
DRM-Digital (Distribution Relay Module)
Multi-function digital protection relay for motor and feeder circuits with Modbus-TCP communication. Typical faults involve current transformer input conditioning errors, relay output solid-state switch degradation, and firmware update corruption.

Common ELECTROSISTEM Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ELECTROSISTEM equipment arriving at our workshop.
- ✓Electrosistem UPS battery charger module output dropout — In Electrosistem EDS-UPS series, the battery charger operates in constant-current/constant-voltage (CCCV) mode. Failure typically stems from rectifier thyristor gate drive circuit degradation, control feedback network capacitor aging, or mains voltage sensing error that causes the charger to incorrectly select charging algorithm.
- ✓Electrosistem SVC-PRO thyristor firing angle instability — The SVC-PRO uses phase-locked loop (PLL) synchronization and thyristor gating circuits to regulate reactive power injection. Instability occurs when the voltage reference signal is corrupted by mains harmonics, the gating pulse isolation circuits fail, or the control processor's AC zero-crossing detection circuitry drifts due to transformer saturation.
- ✓Electrosistem HFC-Active harmonic compensation divergence — The HFC-Active continuously samples load current harmonics and generates opposing PWM current from its inverter. Compensation divergence—where harmonic distortion increases instead of decreasing—typically results from current sensor calibration drift, PWM inverter dead-time misconfiguration, or digital signal processor (DSP) control loop instability caused by firmware version mismatch.
- ✓Electrosistem ESSC-ST soft starter sluggish ramp initiation — Electrosistem soft starters use dual-thyristor phase control with analog ramp voltage generation. Sluggish initiation—delayed motor acceleration or incomplete torque ramp—indicates failure in the triggering pulse generator circuit, decay of coupling capacitors in the ramp generator network, or open gate drive transformer secondary windings affecting thyristor conduction.
- ✓Electrosistem RPC reactive power setpoint drift without cause change — The RPC series microprocessor-based controller reads power factor via current transformer (CT) burden circuits and analog input signal conditioning. Setpoint drift occurs when CT burdens increase due to winding temperature rise, analog multiplexer channel crosstalk develops, or the microprocessor's internal voltage reference slowly ages, causing calibration constants stored in EEPROM to become invalid.
- ✓Electrosistem DRM-Digital Modbus-TCP communication timeouts — Electrosistem DRM-NET modules communicate via Modbus-TCP over Ethernet. Communication timeouts result from Ethernet port driver IC failures, RJ45 connector corrosion in humid industrial environments (common in Indian coastal plants), TCP/IP stack firmware corruption during firmware update interruption, or PHY layer signal integrity degradation in noisy power distribution networks.

Frequently Asked Questions — ELECTROSISTEM Repairs
Does Synchronics repair all Electrosistem product families across India?+
Yes. Synchronics repairs the complete Electrosistem portfolio — UPS systems (EDS-UPS, modular units), reactive power controllers (SVC-PRO, RPC-Series), harmonic filters (HFC-Active), soft starters (ESSC-ST), and digital relays (DRM-Digital). We offer PAN India pickup and repair from our Vadodara facility, with express service available for critical power infrastructure in Delhi, Mumbai, Pune, Hyderabad, Ahmedabad, and Bangalore. Same-day diagnostics and 3-5 day turnaround for most repairs.
What is the typical repair time for an Electrosistem SVC-PRO thyristor stack failure?+
Electrosistem SVC-PRO thyristor failures require full stack replacement and control circuit validation. Synchronics typically completes SVC-PRO repairs in 5-7 business days including thyristor procurement, stack assembly, gate drive circuit testing, and closed-loop reactive power compensation verification. We maintain stock of common Electrosistem thyristors (1200V/1600V, 200-400A ratings) to minimize parts lead time. Critical installations receive priority handling with on-site commissioning support.
Why should I choose Synchronics for Electrosistem power electronics repair over local vendors?+
Synchronics engineers are factory-trained on Electrosistem equipment architecture, control algorithms, and firmware. We maintain calibrated test benches with power analyzers, thermal imaging, and Modbus protocol analyzers — essential for validating complex multi-function units like RPC-Series and DRM-NET. We source genuine Electrosistem spare parts, provide 24-month post-repair warranty, and deliver technical documentation in English and Hindi. Our experience spans 180+ engineers and 1000+ repairs across Siemens, ABB, Danfoss, Schneider, Yaskawa, and 200+ other brands — giving us systems-level understanding that local shops lack.
Can Synchronics help with Electrosistem firmware updates and commissioning?+
Yes. Synchronics provides Electrosistem firmware update service, factory-default configuration loading, and on-site commissioning for UPS, SVC-PRO, and RPC systems. We verify firmware version compatibility, perform pre-update backup, and validate all protection logic and communication protocols post-update. For critical installations (textile mills, pharma plants, steel facilities), we provide witnessed commissioning with load testing documentation and handover training for your in-house maintenance team.
Does Synchronics offer preventive maintenance contracts for Electrosistem equipment?+
Yes. Synchronics offers quarterly and bi-annual preventive maintenance packages covering capacitor health assessment, thyristor gate drive function testing, firmware integrity validation, and calibration drift detection. For Electrosistem UPS and SVC-PRO systems operating in harsh industrial environments (steel mills, cement plants, sugar factories), we recommend quarterly PM to detect aging before catastrophic failure. PM contracts include thermal imaging, harmonic distortion analysis, and written condition reports with repair recommendations.
How do I send my ELECTROSISTEM 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 ELECTROSISTEM 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 ELECTROSISTEM 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 ELECTROSISTEM 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.
