ENERTECH Product Lines We Repair
Our engineers are trained on the full ENERTECH product range. Below are the major product families we service.
ENERTECH PFC (Power Factor Correction) Controllers
Automatic power factor correction units with capacitor bank switching and harmonic suppression. Common issues include stuck relay contacts, capacitor failure, and microcontroller firmware degradation affecting switching accuracy.
ENERTECH Harmonic Filters
Passive and active harmonic filtering solutions for VFD-heavy environments. Frequent failures occur in filter coils, snubber capacitors, and thyristor bridges due to transient spikes from non-linear loads in Indian industrial sites.
ENERTECH Voltage Stabilizers (Industrial Series)
Servo-controlled voltage regulation units rated 100-500 kVA for fluctuation-prone Indian power grids. Typical faults: servo motor wear, transformer tap changer failure, and control board relay damage from voltage transients.
ENERTECH Energy Monitoring Modules
Power metering and harmonic analysis modules integrated into switchboards. Repair involves CT coil diagnostics, isolated DC power supply failures, and RS485 communication board faults affecting real-time energy data logging.
ENERTECH Capacitor Bank Switching Units
Automated detuned capacitor bank controllers with microcontroller-based switching logic. Common failure modes: thyristor short-circuits, gate drive circuit failures, and capacitor pre-discharge resistor burnout.
ENERTECH Transient Surge Suppressors
Metal oxide varistor (MOV) and thyristor-based surge protection modules for power distribution boards. Faults include MOV degradation under repeated transient stress typical in Indian unregulated power environments.

Common ENERTECH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ENERTECH equipment arriving at our workshop.
- ✓Capacitor bank overvoltage and bank tripping — In Indian power grids with unstable voltage profiles, detuned capacitor banks in ENERTECH PFC controllers can be subjected to sustained overvoltage (110-115% rated voltage). This causes dielectric stress and thermal runaway, triggering protection relays and disconnecting the entire bank.
- ✓Thyristor gate drive circuit failure in switching units — ENERTECH harmonic filters and capacitor switching modules use thyristors controlled by optoisolated gate drivers. Moisture ingress, inadequate heat dissipation in dusty Indian mill environments, and transient spikes can degrade the isolation photocoupler and gate resistor networks.
- ✓Control microcontroller lockup or erratic capacitor switching — ENERTECH PFC and EMM modules use embedded microcontrollers sampling voltage and current via analog circuits. Noise from unshielded VFD installations (common in Indian CNC and pump motor applications) couples into low-level analog inputs, causing incorrect switching decisions and reactive power oscillation.
- ✓Transformer tap changer mechanism stuck or slow response — ENERTECH industrial voltage stabilizers use motorized tap changers to regulate 100-500 kVA output. In Indian foundries and steel mills with frequent load transients and dust, mechanical wear on tap contact arms and friction in the drive train cause slow or stuck tap transitions, leaving the output unregulated.
- ✓RS485 communication fault — harmonic data loss or gateway timeouts — ENERTECH Energy Monitoring Modules transmit harmonic and energy data over isolated RS485 networks. Electromagnetic interference from adjacent motor drives and poor cable grounding in Indian industrial panels cause signal corruption, parity errors, and intermittent data loss.
- ✓Harmonic filter coil overheating and insulation breakdown — ENERTECH passive harmonic filters are tuned to specific frequencies. When load harmonics shift (e.g., installation of newer VFD models with different switching patterns), the filter coil absorbs excessive current at off-tuned frequencies, causing core loss heating and eventual winding insulation failure.

Frequently Asked Questions — ENERTECH Repairs
Do you repair ENERTECH equipment across all of India?+
Yes. Synchronics Electronics provides PAN India repair service for ENERTECH power quality and energy management products. We offer free door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, Bangalore, and all other major industrial cities. Equipment is transported safely to our ISO-certified facility in Vadodara, Gujarat, where our 180+ engineers perform repairs. Typical turnaround is 7-10 working days.
How do I know if my ENERTECH PFC controller needs repair?+
Watch for these ENERTECH-specific warning signs: capacitor bank tripping intermittently, reactive power (kVAR) reading stuck or erratic on the display panel, LED fault indicators blinking, or switching relay audible chatter. Also check if power factor is not improving to the set point (typically 0.95 or higher). Contact Synchronics with your error code or symptoms and we will diagnose remotely or arrange on-site inspection in your city.
What spare parts does Synchronics stock for ENERTECH repairs?+
We stock genuine and cross-certified ENERTECH capacitor units, thyristors, gate drive optocouplers, microcontroller modules, and relay cards. For critical ENERTECH components (detuning reactors, power transformers), we source directly from ENERTECH or qualified manufacturers. We maintain a 48-hour parts availability promise to minimize repair delays for Indian customers.
Can ENERTECH harmonic filters be repaired or must they be replaced?+
Many ENERTECH harmonic filter faults are repairable. Coil rewinding, capacitor unit replacement, and thyristor bridge swaps are our standard services. However, if core damage is severe or the filter tuning frequency no longer matches your plant's load (e.g., after VFD upgrades), we recommend replacement. We help assess filter efficiency with a harmonic survey and provide cost-benefit analysis before repair or replacement decision.
Does Synchronics offer on-site ENERTECH commissioning or testing after repair?+
Yes. Upon request and for large installations, we provide on-site commissioning and harmonic testing in your city. Our engineers verify power factor correction, measure total harmonic distortion (THD) before and after, and validate all protective settings. We also train your plant's electrical staff on ENERTECH operation and maintenance best practices specific to Indian industrial environments.
How do I send my ENERTECH 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 ENERTECH 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 ENERTECH 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 ENERTECH 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.
