ELECTRIC SYSTEM INC Product Lines We Repair
Our engineers are trained on the full ELECTRIC SYSTEM INC product range. Below are the major product families we service.
ESI PowerGuard UPS Series
Three-phase uninterruptible power supplies ranging from 10 kVA to 500 kVA. Common faults include battery module failures, rectifier card burnout, and inverter IGBT degradation leading to transfer relay chatter and nuisance shutdowns.
ESI SoftStart Controllers
Electronic soft-starting devices for three-phase motors up to 250 kW. Reduces inrush current and mechanical stress. Repair involves thyristor gate drive circuit faults, current transducer errors, and phase-control timing drift.
ESI PowerFactor Correction Units
Automatic power factor correction (APFC) panels for industrial loads. Common failures include capacitor bank short circuits, contactor coil burnout, microcontroller reset loops, and harmonic filter element degradation.
ESI DIN-Rail Power Supplies
Industrial-grade 24 VDC and 48 VDC switching power supplies for control circuits and PLC inputs. Susceptible to capacitor dry-out, output voltage droop under load, and no-load regulation drift after 5-7 years of operation.
ESI Distribution Control Cabinets
Custom-built electrical distribution and control enclosures with integrated metering, remote monitoring, and load-switching logic. Failures stem from relay chatter, terminal oxidation, contactor pitting, and communication module dropout.

Common ELECTRIC SYSTEM INC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ELECTRIC SYSTEM INC equipment arriving at our workshop.
- ✓UPS Battery Module Failed - No Backup Power — Electric System Inc. PowerGuard UPS battery strings degrade due to sulphation in Indian high-temperature environments. Lead-acid modules lose capacity after 3-5 years in facilities without temperature control. Charger overvoltage settings also accelerate lead crystal growth.
- ✓Rectifier MOSFET Short - No Input Power Conversion — Electric System Inc. PG-3 series rectifier boards use first-generation MOSFETs prone to gate oxide failure under high dV/dt transients from grid switching. Unfiltered mains spikes and weak snubber capacitors trigger cascade failures across the three-phase bridge.
- ✓Inverter IGBT Failure - Load Cannot Transfer — Electric System Inc. UPS inverter IGBTs fail due to junction temperature cycling when thermal interface material degrades between die and heatsink. Poor heatsink contact and accumulated dust in Indian industrial environments cause hot-spot formation and premature wear-out.
- ✓Soft Starter Thyristor Dropout - Erratic Motor Starting — Electric System Inc. SoftStart controllers experience thyristor gate driver circuit failures caused by dV/dt spike coupling into gate isolation transformers. High ambient humidity in coastal and monsoon regions causes PCB creepage and leakage currents in gate drive optocouplers.
- ✓APFC Capacitor Bank Short Circuit - Blown Contactor — Electric System Inc. PowerFactor correction capacitors are rated for indoor use but accumulate moisture in poorly ventilated cabinet spaces common in Indian textile mills and cement plants. Dielectric breakdown under reactive load surge causes catastrophic short, tripping the incoming contactor.
- ✓Power Supply Output Voltage Droop Under Load — Electric System Inc. DIN-rail 24 VDC supplies suffer output regulation drift due to feedback error amplifier capacitor drying out and output filter capacitor ESR increase. In Indian high-temperature server rooms and plant control cabinets, ambient temperature exceeds design assumptions (55°C vs. 40°C rated).

Frequently Asked Questions — ELECTRIC SYSTEM INC Repairs
Do you repair Electric System Inc. equipment anywhere in India?+
Yes. Synchronics repairs the full Electric System Inc. product range - UPS systems, soft starters, APFC units, power supplies, and distribution control cabinets. We offer PAN-India door-step pickup and delivery service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other major cities. All repairs are carried out at our certified facility in Vadodara, Gujarat.
My Electric System Inc. UPS shows E04 or E07 error codes. What does this mean?+
E04 indicates a battery test failure - the UPS detected low battery string voltage during self-test, usually meaning one or more battery modules have failed. E07 signifies rectifier input failure, often caused by a blown input fuse or MOSFET short. Synchronics can diagnose both with our specialized ESI UPS test equipment. Battery string testing costs 1500 Rs. and takes 2 hours. MOSFET replacement including parts and labour typically runs 8000-12000 Rs.
Can you repair Electric System Inc. soft starters with burnt thyristor gates?+
Absolutely. Burnt or shorted thyristor gate driver circuits are one of our most common SoftStart repairs. We replace the failed optocoupler IC, re-solder the gate pulse transformer leads, and recalibrate the phase angle potentiometer. The unit is then tested on a 30 kW motor load to verify ramp-up timing and current limiting function. Turnaround is typically 5-7 working days.
What is the cost to replace a failed capacitor bank in an ESI APFC unit?+
Cost depends on the kVAR rating - a 50 kVAR replacement capacitor set runs approximately 15000-22000 Rs. including labour for removal, terminal cleaning, and contactor inspection. We recommend replacing all capacitors even if only one has failed, as age-matched sets ensure balanced reactive current distribution and reduce stress on switching contactors. We also provide a 12-month warranty on replacement capacitor banks.
How quickly can Synchronics repair my Electric System Inc. UPS during peak monsoon season?+
Monsoon season brings extended repair timelines due to logistics, but our Vadodara facility operates year-round with dedicated UPS repair benches. For UPS failures we aim for 10-15 working day turnaround including pickup, diagnostics, component replacement, and load testing. For critical 24/7 operations, we offer on-site repair at our engineers' day rate (approximately 3500 Rs. per engineer per day plus parts). Advance booking during July-September is strongly recommended.
How do I send my ELECTRIC SYSTEM INC 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 ELECTRIC SYSTEM INC 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 ELECTRIC SYSTEM INC 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 ELECTRIC SYSTEM INC 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.
