EQS Product Lines We Repair
Our engineers are trained on the full EQS product range. Below are the major product families we service.
EQS Power Quality Analysers
Multi-parameter power quality measurement and logging instruments for harmonic analysis, voltage distortion, and flicker measurement. Common faults include display panel failures, SD card logging errors, and sensor signal attenuation affecting measurement accuracy.
EQS APFC (Automatic Power Factor Correction) Controllers
Microprocessor-based capacitor bank controllers with integrated harmonic filtering and reactive power compensation. Typical repair issues involve thyristor failures, relay contact oxidation, transformer saturation, and firmware corruption affecting switching sequences.
EQS Harmonic Filter Units
Passive and active harmonic suppression systems designed for variable frequency drive installations and non-linear loads in Indian textile mills and automotive plants. Repair concerns centre on inductor winding insulation breakdown, capacitor bank resonance imbalance, and filter tuning drift.
EQS Energy Management Modules
IoT-enabled power monitoring and data logging systems for consumption tracking and billing accuracy. Common defects include Ethernet interface failures, real-time clock battery depletion, and cloud synchronisation timeouts.
EQS Safety Switchgear and Contactor Interface Units
Safety-rated electrical switching devices with integrated status monitoring for motor control centres and distribution boards. Failure modes include solenoid coil burnout, mechanical latch wear, and control signal isolation faults.

Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common EQS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EQS equipment arriving at our workshop.
- ✓EQS Power Quality Analyser display frozen or unresponsive — Firmware crash due to corrupted SD card file system or exceeded memory buffer during continuous harmonic logging. Indian textile mills running 24/7 operations frequently encounter this when data logging intervals are too short.
- ✓APFC capacitor bank switching erratic or delayed — Thyristor gate drive circuit degradation or control firmware logic error preventing proper phase-angle timing. This is common in coastal pharmaceutical plants where salt spray corrodes PCB traces and relay contacts.
- ✓Harmonic filter output voltage distortion not reducing — Capacitor bank resonance shift due to capacitance drift, loose inductor winding connections, or tuning frequency mismatch. Common in automotive plants with variable VFD loading patterns.
- ✓EQS Energy Management Module losing Ethernet connectivity or cloud sync failures — Network interface chip failure, corrupted TCP/IP stack firmware, or exhausted internal flash memory preventing packet buffering. Happens when polling intervals exceed module buffer capacity.
- ✓EQS Safety Switchgear contactor coil remains de-energised despite control signal — Solenoid coil open circuit or reduced insulation resistance, mechanical plunger jamming, or control signal isolation failure in interface module. Humid environments in Indian food processing plants accelerate coil burnout.
- ✓Harmonic analyser sensor readings drifting or unstable — Voltage/current transducer calibration drift, loose sensor connectors, or analogue-to-digital conversion noise from nearby VFD interference. Common in Indian steel mills with high electromagnetic noise.

Frequently Asked Questions — EQS Repairs
Do you repair EQS equipment anywhere in India?+
Yes. Synchronics repairs the full EQS product range - power quality analysers, APFC controllers, harmonic filters, energy management modules, and safety switchgear. We offer PAN India door pickup and courier service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, Kolkata and all other major cities. All repairs are completed in our 180-engineer facility in Vadodara, Gujarat with turnaround times of 5-10 working days.
What is the typical turnaround time for EQS power quality analyser repair?+
EQS power quality analysers typically require 7-10 working days for diagnosis, component replacement, firmware reload, and calibration testing. Urgent repairs can be expedited to 48-72 hours if parts are in stock. Synchronics maintains spare capacitor boards, SD card modules, and sensor interface cards for common EQS analyser models.
Does Synchronics repair EQS APFC controllers with mixed capacitor bank configurations?+
Absolutely. We regularly service EQS APFC units with hybrid capacitor banks combining different voltage ratings and KVAr steps. Our engineers recalibrate switching algorithms to match your actual capacitor set, perform load-step testing, and verify KVAR accuracy within ±5%. We also upgrade older EQS-APC models with modern thyristor modules for improved reliability.
Can Synchronics help if my EQS harmonic filter is not meeting THD targets?+
Yes. If your EQS harmonic filter is not achieving <5% THD, Synchronics performs a complete power audit including load characterisation, resonance mapping, and capacitor impedance testing. We identify whether the issue is tuning drift, component degradation, or changed facility loading. We then either retune existing equipment or recommend component upgrades with full before-after harmonic spectrum analysis.
Do you provide on-site support for EQS control system integration with ABB or Siemens PLCs?+
Synchronics offers on-site commissioning support for EQS-to-PLC integration projects in Mumbai, Pune, Ahmedabad, Chennai, and Hyderabad regions. We configure EQS Modbus or Ethernet gateway modules, program PLC IO mapping, and conduct system-level testing. For remote sites, we provide remote support via TeamViewer and detailed commissioning documentation.
How do I send my EQS 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 EQS 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 EQS 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 EQS 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.
