EPGE Product Lines We Repair
Our engineers are trained on the full EPGE product range. Below are the major product families we service.
EPGE PSM Series - Power Supply Modules
Industrial regulated power supplies for control systems, PLCs, and instrumentation. Common issues include transformer burnout from mains surge, capacitor swelling due to thermal stress, and rectifier diode failures in high-dust environments typical of Indian foundries and mills.
EPGE ASD Series - Adjustable Speed Drives
Compact AC variable frequency drives for pumps, compressors, and spindle motors in textile and paper mills. Frequent failures include IGBT module delamination in humid coastal regions, EMC filter degradation from harmonic distortion, and firmware corruption in drives retrofitted with Indian industrial networks.
EPGE SERVO-LINK Series - Servo Amplifiers
Precision servo drives for CNC machines, injection moulding equipment, and packaging automation. Typical repair needs: Hall sensor signal loss in motion control, resolver feedback wiring degradation, and DSP firmware updates for compatibility with modern encoder interfaces used in Indian manufacturing.
EPGE LV Series - Low Voltage Distribution Electronics
Control modules for switchgear, soft starters, and motor protection systems in power distribution networks. Common faults: triac gate drive circuit failures, optocoupler burnout from voltage transients in Indian grid conditions, and contact welding in solid-state switching stages.
EPGE TEST-GEN Series - Test & Measurement Systems
Precision signal generators and power analysers for automotive testing, calibration labs, and quality control. Repair challenges: analog front-end component drift, DAC non-linearity, and thermal sensor failures in high-vibration factory environments common across Indian automotive OEMs.

Common EPGE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EPGE equipment arriving at our workshop.
- ✓IGBT module thermal delamination and short circuit — Repeated thermal cycling in PSM and ASD series drives operating in Indian manufacturing environments with inadequate cooling or blocked heatsinks. Solder fatigue between semiconductor die and substrate leads to internal shorts and gate-drive failures.
- ✓Capacitor swelling and electrolyte leakage — Aluminum electrolytic capacitors in EPGE power supplies degrade due to prolonged exposure to high ripple current and ambient temperatures above 45°C, common in Indian foundries and textile mills. Especially prevalent in older PSM-110 and PSM-230 units installed pre-2010.
- ✓EMC filter degradation and harmonic injection — EPGE ASD drives in plants with multiple high-power industrial loads generate harmonic currents that degrade filter capacitors in the EMC stage. Indian manufacturing sectors using legacy switchgear often lack adequate harmonic filtering, accelerating EPGE filter burnout.
- ✓Hall sensor signal loss in servo drives — EPGE SERVO-LINK amplifiers rely on accurate Hall sensor feedback from motor windings. In Indian metalworking and precision machining shops, vibration and coolant contamination cause connector corrosion and sensor wiring insulation breakdown, resulting in commutation errors.
- ✓DSP firmware corruption and boot failure — EPGE drives may experience firmware corruption due to power loss during software updates, electrostatic discharge during maintenance, or incompatible firmware versions loaded during troubleshooting by non-authorized technicians in Indian plants.
- ✓Triac gate drive circuit failure in LV modules — EPGE LV series solid-state switches employ triac gate drive circuits sensitive to voltage transients common in Indian industrial power grids. Lack of adequate surge protection and high dV/dt conditions cause gate-drive IC burnout and latching failures.

Frequently Asked Questions — EPGE Repairs
Do you repair EPGE equipment anywhere in India?+
Yes. Synchronics repairs the full EPGE product range — PSM power supplies, ASD drives, SERVO-LINK amplifiers, LV distribution modules, and TEST-GEN systems. We offer PAN India door pickup and courier service from all major cities: Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and over 500 Indian towns. Your EPGE equipment is repaired in our factory-certified facility in Vadodara, Gujarat, with same-day diagnostics and transparent technical reporting.
What is the typical repair time for EPGE ASD drive with IGBT failure?+
EPGE ASD drives with IGBT module short-circuit typically require 5-7 working days for full repair and testing. This includes thermal imaging diagnostics, IGBT module replacement, power-stage testing under load, and firmware verification. Synchronics maintains stock of common EPGE IGBT modules (6A, 12A, 16A variants) and can accelerate repairs for critical plant shutdowns. Emergency same-shift repairs are available for customers with onsite technician support.
Can Synchronics repair EPGE servo drives with custom encoder interfaces?+
Yes. EPGE SERVO-LINK amplifiers are frequently retrofitted in Indian CNC and precision machinery with different encoder protocols (SSI, CANopen, PROFIBUS). Synchronics has successfully repaired SERVO-LINK drives with Heidenhain, Siemens, and local encoder integrations. We perform full functional testing with your original motor and encoder, plus provide firmware upload support for encoder calibration parameters.
What warranty and guarantee does Synchronics provide on EPGE repairs?+
All EPGE repairs come with a 2-year warranty on replaced components and a 90-day return-to-work guarantee. If a repaired EPGE drive fails within 90 days due to the same fault, Synchronics repairs or replaces it at no charge. Our warranty covers parts and labour, excluding physical damage or misapplication. Indian customers also receive detailed repair reports with root-cause analysis and preventive maintenance recommendations.
Do you offer preventive maintenance services for EPGE drives in my plant?+
Yes. Synchronics provides onsite preventive maintenance contracts for EPGE equipment at Indian manufacturing facilities. Services include thermal imaging of power stages, capacitor aging assessment, firmware version audits, and harmonic quality analysis. We can schedule quarterly or bi-annual visits to textile mills, foundries, and automotive plants across India, with spare parts and consumables provided on retainer basis to minimize your downtime risk.
How do I send my EPGE unit for repair?+

What is the cost of repairing a EPGE 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 EPGE 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 EPGE 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.
