SP.EL. Equipment We Repair — By Category
SP.EL. Product Lines We Repair
Our engineers are trained on the full SP.EL. product range. Below are the major product families we service.
SP.EL. Thyristor Power Controllers
Phase-control and full-wave rectifier modules for AC-DC conversion in metal processing, heat treatment, and electroplating. Common faults include thyristor gate circuit failures, snubber capacitor degradation, and heat sink thermal issues. Synchronics performs component replacement and thermal re-calibration.
SP.EL. PLC and Logic Controllers
Compact programmable controllers for process automation, sequencing, and interlocking in textile mills, cement plants, and foundries. Typical failures involve relay cards, input/output module burnout, and EPROM corruption. Synchronics offers diagnostics and board-level repair with memory restoration.
SP.EL. SCR Firing Control Units
Gate-pulse generators and firing circuits for thyristor-based power rectifiers in rolling mills, induction furnaces, and DC motor drives. Failures typically stem from opto-coupler damage, sync transformer burnout, or pulse transformer windings. Synchronics recalibrates firing angles and replaces magnetic components.
SP.EL. Soft Starter Modules
Electronic soft-starters for AC motor acceleration and deceleration control, reducing inrush current and mechanical shock. Typical defects include triac short-circuit, current-sensing transducer failure, and control PCB solder cracks. Synchronics performs board rework and triac replacement.
SP.EL. Temperature and Process Controllers
Analog and digital controllers for furnace temperature, pressure vessel control, and industrial ovens used in heat treatment and ceramic manufacturing. Common issues include thermocouple input circuit faults, relay output sticking, and calibration drift. Synchronics performs sensor interface repair and software recalibration.
SP.EL. Chopper and Buck Converter Modules
PWM-based DC-DC converters for adjustable DC output in metal treatment, electrowinning, and battery charging applications. Frequent failures include MOSFET gate drive circuit faults, free-wheeling diode reverse recovery damage, and capacitor ESR rise. Synchronics replaces semiconductors and re-tunes feedback loops.

Common SP.EL. Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SP.EL. equipment arriving at our workshop.
- ✓Thyristor gate circuit misfiring or complete failure — SP.EL. thyristor controllers rely on opto-isolated gate drives. Extended thermal cycling causes opto-coupler degradation, leading to weak or absent gate pulses. Industrial electrical noise can also couple into the gate control transformer primary.
- ✓Phase angle control not responding to setpoint — SP.EL. firing control units use analog ramp-and-compare circuits for phase-angle adjustment. Failure occurs when the ramp capacitor leaks, the setpoint potentiometer becomes intermittent, or the comparison op-amp input bias current drifts due to age.
- ✓Triac or SCR conducting continuously (short-circuit mode) — SP.EL. soft-starter triacs fail short when exposed to repeated over-current transients or surge voltages without adequate snubber protection. Gate-triggered latch-up can also occur if gate-cathode voltage spikes exceed manufacturer limits.
- ✓Output voltage unstable or drifting out of specification — SP.EL. buck converters and DC chopper modules drift when feedback resistor dividers age, the error amplifier op-amp offset drifts, or the reference voltage regulator zener fails. Transformer core saturation can also reduce efficiency and distort output.
- ✓Relay output stuck or contacts pitted (no coil de-energization) — SP.EL. PLC relay outputs fail when contact erosion from arc pitting creates a thin conductive bridge, or coil insulation breakdown allows continuous current draw. Mechanical sticking occurs in dusty environments where copper oxide builds up on contact surfaces.
- ✓Temperature sensor input reading incorrect or unstable — SP.EL. process controllers use RTD or thermocouple inputs with precision excitation circuits. Failures stem from broken thermocouple wire inside the controller terminal block, input amplifier offset drift, or moisture ingress into the sensor connector causing intermittent contact resistance.

Frequently Asked Questions — SP.EL. Repairs
Do you repair SP.EL. equipment anywhere in India?+
Yes. Synchronics repairs the complete SP.EL. product range - thyristor controllers, PLC modules, soft-starters, and firing units. We operate PAN India door-to-door collection from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, Surat, and all major cities. All repairs are conducted at our ISO-certified facility in Vadodara, Gujarat with same-day diagnostic turnaround.
Can you repair SP.EL. thyristor modules that show erratic firing angle control?+
Absolutely. Erratic firing in SP.EL. thyristor controllers usually stems from opto-coupler degradation, ramp capacitor leakage, or gate transformer insulation breakdown. Synchronics performs complete gate drive circuit diagnostics, replaces aging components, and performs a full 0-180 degree phase-scan test under actual load. We also verify snubber network integrity to prevent recurrence.
What is your warranty on SP.EL. controller repairs?+
All SP.EL. repairs at Synchronics carry a 12-month comprehensive warranty against component failure and workmanship defects. We provide 90-day advance notice if a repaired unit develops secondary faults due to manufacturing latent defects. In-warranty repairs are free, including return shipping across India via our logistics partners.
Can you restore SP.EL. PLC memory if the EPROM or firmware has become corrupted?+
Yes. Synchronics has developed in-house protocols for SP.EL. PLC firmware extraction, verification, and re-programming. We recover backup program logic from your documentation or on-site hardware backups. For orphan PLC modules where original code is unavailable, we design replacement logic matching your process sequence. Turnaround is 3-5 working days.
Do you stock genuine SP.EL. spare parts or use equivalents?+
Synchronics maintains authentic SP.EL. component inventory for common failures - opto-couplers, triacs, capacitors, relays, and transformer modules. For long-obsolete SP.EL. parts, we source pin-compatible, cross-referenced equivalents from IEC-certified suppliers and validate functionality before assembly. All parts carry full traceability and original packing.
How do I send my SP.EL. 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 SP.EL. 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 SP.EL. 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 SP.EL. 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.
