ENERTRONIC Equipment We Repair — By Category
ENERTRONIC Product Lines We Repair
Our engineers are trained on the full ENERTRONIC product range. Below are the major product families we service.
RECTOMAC Thyristor Rectifiers
Industrial-grade 6-pulse and 12-pulse thyristor rectifiers for DC power generation. Common failures include capacitor degradation under ripple current stress, thyristor firing circuit faults, and cooling fan bearing wear. Load regulation drift and output voltage ripple are typical symptoms requiring Synchronics intervention.
CONVERTOMAT Power Converters
Static power conversion modules for galvanic isolation and voltage step-down in cement, steel, and chemical industries. Prone to transformer winding insulation breakdown, diode bridge failures, and control card logic faults under thermal stress and harmonic distortion.
PULSOMAT Pulse Control Systems
Digital and analog pulse-width modulation controllers for thyristor firing in rectifier stacks. Aging optocoupler interfaces, gate driver IC failures, and firmware corruption are common repair demands. Synchronics specializes in EPROM reprogramming and driver module replacement.
CAPACIBANK Energy Storage Modules
High-voltage electrolytic capacitor banks for ripple filtering and energy buffering in DC link applications. Electrolyte leakage, voltage reversal damage, and thermal runaway are primary failure modes. Synchronics performs capacitor matching, ESR testing, and thermal design review.
DRIVECOAT Thyristor Driver Modules
Gate drive and protection circuits for series-connected thyristors in high-power rectifier bridges. Dv/dt-induced false triggering, snubber network degradation, and fiber-optic coupling failures are recurring issues. Temperature cycling accelerates ceramic substrate cracks.
COOLOMAT Thermal Management Units
Liquid cooling and air-blast systems for thyristor stacks and power modules in high-current rectifier systems. Coolant contamination, heatsink fouling, and thermostat sensor malfunction reduce thermal dissipation. Synchronics cleans, refills, and pressure-tests Enertronic cooling jackets.

Common ENERTRONIC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ENERTRONIC equipment arriving at our workshop.
- ✓Capacitor bank voltage collapse and ripple rise — Electrolytic capacitors in Enertronic CAPACIBANK modules degrade due to prolonged DC stress, ambient heat, and ripple current cycling. ESR increases, capacitance drops, and voltage regulation fails. This is accelerated in Indian tropical climates with inconsistent cooling.
- ✓Thyristor gate drive circuit failure and no-fire condition — Enertronic DRIVECOAT and PULSOMAT modules suffer fiber-optic coupler degradation, optocoupler LED aging, and gate resistor open circuits. Thermal cycling and high dv/dt transients accelerate oxide interface breakdown, causing intermittent triggering or complete lock-out.
- ✓Output voltage ripple and DC link instability — Degraded snubber networks, failed rectifier diodes in secondary filtering stages, and worn PULSOMAT phase-control circuits in Enertronic RECTOMAC units cause harmonic distortion. Control loop instability and load transient overshoot trigger nuisance shutdowns.
- ✓Water-cooled Enertronic rectifier coolant leakage and thermal runaway — Enertronic COOLOMAT thermal modules suffer seal degradation, corrosion of aluminum cooling jackets, and mineral deposits in Indian hard water conditions. Blockages reduce flow, causing local hotspots that trigger thyristor junction temperature alarms and premature power-down.
- ✓EPROM/EEPROM firmware corruption and firing angle lock-up — Enertronic PULSOMAT digital controllers experience flash memory bit flips from electromagnetic interference (EMI), power supply transients, and ambient temperature extremes common in Indian foundries and mills. Corrupted lookup tables prevent proper phase sequencing.
- ✓Intermittent rectifier bridge firing and load current dropout — Enertronic RECTOMAC 6-pulse and 12-pulse bridges experience thyristor latching, turn-off circuit failures, and di/dt snubber degradation under load transient stress. Poor PCB solder joints on DRIVECOAT modules worsen contact intermittency in humid Indian environments.

Frequently Asked Questions — ENERTRONIC Repairs
Do you repair Enertronic equipment anywhere in India?+
Yes. Synchronics repairs the complete Enertronic product portfolio — RECTOMAC rectifiers, PULSOMAT controllers, DRIVECOAT modules, CAPACIBANK filter systems, and COOLOMAT thermal units. We offer PAN India pickup and delivery from Vadodara, Gujarat, with service depots in Mumbai, Delhi, Pune, Chennai, Hyderabad, and Ahmedabad. Most repairs are returned within 7-10 working days.
How do you diagnose a failing Enertronic RECTOMAC thyristor rectifier?+
Synchronics uses Enertronic-specific test procedures: load regulation DC measurement under rated current, ripple voltage harmonic analysis via FFT, thyristor forward voltage curve-tracing at operating current, gate drive pulse timing oscilloscopy, and thermal imaging of capacitor banks and heatsinks. We also perform dielectric strength testing on transformer windings and insulation resistance on isolated circuits. Full diagnostic reports are provided with root-cause analysis.
What is the turnaround time for Enertronic PULSOMAT digital controller repair?+
Standard PULSOMAT firmware and optocoupler repairs take 5-7 working days. Complex rework involving microcontroller replacement or EPROM reprogramming may extend to 10-14 days. Synchronics offers expedited 48-hour turnaround for critical emergency repairs on cement and steel mill equipment, with technician-assisted commissioning. Rush surcharge applies.
Can Synchronics upgrade old Enertronic RECTOMAC analog rectifiers to digital control?+
Yes. We retrofit Enertronic analog RECTOMAC bridges with new digital PULSOMAT controllers, modern DRIVECOAT thyristor drivers, and upgraded snubber networks. This improves voltage regulation accuracy, reduces harmonic distortion, and adds remote monitoring capability. Full integration testing ensures compatibility with existing transformer and load equipment. Upgrade cost is typically 40% of new rectifier replacement.
What warranty do you provide on Enertronic repair and what does it cover?+
Synchronics provides 12 months parts and labor warranty on all Enertronic repairs from date of shipment. Warranty covers the repaired circuit or module function under normal operating conditions. It does not cover damage from power surges, incorrect installation, coolant contamination, or unauthorized modifications. Extended 24-month warranties are available for critical process equipment at additional cost.
How do I send my ENERTRONIC 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 ENERTRONIC 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 ENERTRONIC 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 ENERTRONIC 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.
