Synchronics repairs the entire ESITRON product portfolio — including their DIN-rail PSU series, redundancy modules, power distribution units, and integrated power management systems. With 180+ engineers and 30 years' combined experience, we stock ESITRON spare components, perform full capacity testing on faulty units, and deliver rapid turnarounds for critical pharmaceutical and food production lines. Indian plant managers trust Synchronics for ESITRON repairs because we understand both the electronics and the regulatory compliance these sectors demand.
ESITRON power supply and redundancy system repair across all industrial voltage ratings and modular configurations.
ESITRON Product Lines We Repair
Our engineers are trained on the full ESITRON product range. Below are the major product families we service.
ESITRON DIN-Rail Switched-Mode Power Supplies
Compact, single-phase and three-phase PSU modules (5W to 960W) for industrial control cabinets. Common faults include capacitor drying, transformer winding short-circuits, and output regulation failures under thermal stress in humid Indian climates.
ESITRON Redundancy and Power Distribution Modules
Hot-swap redundant PSU controllers and power distribution units (PDU) ensuring zero-downtime power switching. Repairs often involve faulty relay circuits, diode bridge failures, and redundancy logic PCB faults.
ESITRON Industrial Battery Chargers
Three-phase mains-powered chargers for backup battery banks in pharmaceutical cold storage and food production facilities. Typical failures: thyristor misfiring, transformer saturation, and charge-control circuit instability.
ESITRON Power Factor Correction and Filtering Units
Active and passive harmonic filters and PFC controllers for reducing THD in motor-heavy textile mills and food processing plants. Common issues: capacitor bank failures, control board microprocessor crashes, and sensing circuit faults.
ESITRON Modular Uninterruptible Power Supply (UPS) Systems
Scalable modular UPS platforms combining ESITRON PSU modules with battery interfaces and real-time monitoring dashboards. Repairs address module synchronization failures, battery isolation contactor faults, and display communication breakdowns.
ESITRON Remote Monitoring and Control Interfaces
Industrial-grade Ethernet and serial gateway modules for remote power system diagnostics and alarm management. Common defects: network isolation transformer burnout, microcontroller flash corruption, and RS-485 transceiver failures.

Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common ESITRON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ESITRON equipment arriving at our workshop.
- ✓ESITRON PSU output voltage drift and instability — Aging feedback resistor networks and optocoupler degradation in ESITRON switched-mode designs cause feedback loop instability. High ambient temperatures in Indian manufacturing floors accelerate this deterioration.
- ✓ESITRON redundancy module failover timeout errors — Faulty relay switching contacts in ESITRON RDM series or degraded sensing transistors delay PSU switchover detection, triggering redundancy failure alarms and potential power loss to critical circuits.
- ✓ESITRON battery charger CC-CV mode transition failure — Control circuit instability or charge-sensing diode faults in ESITRON BC series prevent smooth transition from constant-current to constant-voltage charging, overcharging batteries and damaging cells.
- ✓ESITRON PFC/THD filter capacitor bank burnout — Harmonic distortion spikes from uncontrolled motor loads or grid transients stress ESITRON capacitor banks beyond rated ripple current. Cheap aftermarket replacement PSUs worsen harmonic content.
- ✓ESITRON UPS modular synchronization desync and current hogging — Microprocessor firmware corruption or clock slippage in ESITRON UPS-MOD parallel operation logic causes unequal load sharing between modules, stressing individual units and triggering thermal shutdown.
- ✓ESITRON remote gateway Ethernet isolation transformer core saturation — Transient overvoltage events on Ethernet lines or sustained common-mode current from poor grounding in Indian factory installations cause isolation transformer saturation in ESITRON GATEWAY-ETH units.

Frequently Asked Questions — ESITRON Repairs
Do you repair ESITRON equipment anywhere in India?+
Yes. Synchronics Electronics repairs the full ESITRON product range — DIN-rail PSUs, redundancy modules, battery chargers, PFC/harmonic filters, UPS systems, and remote monitoring gateways. We offer PAN-India door pickup and courier service from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, and 50+ other cities. All repairs are performed in our Vadodara, Gujarat facility by certified engineers with direct access to ESITRON datasheets and spare component inventories.
What makes ESITRON power supplies fail in Indian manufacturing environments?+
ESITRON equipment in India typically fails due to thermal stress from high ambient temperatures, voltage instability on older grid supplies, and harmonic distortion from unfiltered motor loads. Dust ingress into DIN-rail modules, humidity-induced corrosion on PCB traces, and poor installation grounding also accelerate failure modes. Synchronics has repaired 200+ ESITRON units, and we design preventive measures tailored to each customer's site conditions — whether pharmaceutical cold storage, textile mills, or semiconductor fabs.
How long does ESITRON PSU and redundancy module repair take?+
Routine repairs (capacitor replacement, relay cleaning, feedback network tuning) take 3-5 working days. Complex faults (transformer rewind, microprocessor reprogramming, full redundancy logic testing) require 7-10 days. Synchronics stocks common ESITRON spare parts and offers expedited 48-hour turnaround for critical power outage situations. We provide daily status updates and can perform on-site installation if needed at Mumbai, Delhi, or Vadodara locations.
Are ESITRON components sourced directly from the manufacturer or aftermarket suppliers?+
Synchronics uses genuine ESITRON components wherever possible — including optocouplers, relays, capacitors, and isolation transformers sourced through official distributors. For legacy ESITRON models where manufacturer parts are unavailable, we use cross-qualified industrial-grade replacements that meet or exceed ESITRON specifications. All replaced components are tested on-equipment before sign-off to ensure same reliability and lifespan as originals.
Can Synchronics repair ESITRON equipment still under warranty?+
Yes. Synchronics is an authorized third-party service partner recognized by many Indian pharma, food, and semiconductor companies for warranty-valid ESITRON repairs. We maintain complete repair documentation, provide detailed test reports, and invoice through GST-compliant channels. If your equipment is still under ESITRON manufacturer warranty, we recommend contacting the OEM first; however, for faster turnaround or out-of-warranty units, Synchronics offers professional, traceable repairs at lower cost than ESITRON direct service.
How do I send my ESITRON 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 ESITRON 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 ESITRON 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 ESITRON 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.
