SSB Equipment We Repair — By Category
SSB Product Lines We Repair
Our engineers are trained on the full SSB product range. Below are the major product families we service.
Powerstarts (PS22, PS45, PS100 Series)
SSB's flagship soft starter range for three-phase AC motor acceleration and deceleration. Common faults include thyristor firing failures, control board malfunctions, overvoltage trip events, and communication loss. These units control motor inrush current in compressors, pumps, and fans across Indian processing industries.
SSB Motor Controllers and Contactors
Programmable motor control relays and contactor units for automated motor sequencing. Repair issues include relay coil burnout, digital input/output module failure, and PLC communication errors. Widely used in textile mills, sugar plants, and steel facilities.
Power Electronics Modules (Thyristor & Diode Packs)
Discrete power semiconductor assemblies used in SSB soft starters for current regulation. Failures manifest as open circuits, short circuits, or thermal runaway. Critical components requiring precision rework and hot-test validation.
SSB Control Boards and PCB Assemblies
Analog and digital control circuit boards managing soft starter ramp rates, current limits, and fault detection. Common defects include capacitor aging, gate-drive circuit failure, and software corruption. Synchronics offers full board-level repair and firmware reprogramming.
Communication Modules (Profibus, Ethernet Gateways)
Industrial network interface cards allowing SSB soft starters to integrate with factory PLCs and SCADA systems. Faults include port failures, protocol stack errors, and cable connector degradation. Essential for Industry 4.0 deployments in Indian smart factories.

Common SSB Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SSB equipment arriving at our workshop.
- ✓Thyristor gate drive circuit failure — SSB soft starters rely on precise gate-drive pulses to trigger thyristors. Aging optocouplers, failed gate resistors, or damaged isolation transformers prevent proper thyristor firing, causing the starter to lock in current-limit mode or trip repeatedly.
- ✓Overvoltage protection relay nuisance trips — SSB soft starters monitor supply voltage using analog comparator circuits. Component drift, capacitor aging, or EMI from nearby drives causes false overvoltage faults (typically >440V trip thresholds). Common in plants with unstable power supplies or single-phase loading.
- ✓Thermal runaway of power thyristors — Repeated soft-start cycles in high-ambient environments (foundries, furnace rooms) degrade junction quality in SSB thyristor packs. Gate-drive parasitic oscillations or insufficient heat-sinking accelerates junction degradation, eventually causing permanent device failure and restart lockout.
- ✓Control board microprocessor corruption or hang — Power supply spikes, firmware version incompatibility, or EEPROM wear-out cause SSB control boards to reset randomly or enter bootloader mode. Symptoms include no display output, no soft-start function, and unresponsive to keypad commands.
- ✓Profibus communication timeout errors — SSB communication modules transmit protocol frames using isolated RS-485 or fiber-optic transceivers. Cable termination resistance drift, transceiver IC failure, or software handshake errors cause 'Comms Lost' faults in networked soft starters, halting production in multi-unit installations.
- ✓Current-limit feedback loop instability — SSB soft starters use analog current-sense circuits to regulate motor inrush. Worn current-transformer secondaries, integrator capacitor leakage, or reference voltage drift cause oscillatory ramp behavior or failure to reach full voltage, resulting in motor stall or nuisance motor overload trips.

Frequently Asked Questions — SSB Repairs
Do you repair SSB soft starters anywhere in India?+
Yes. Synchronics repairs the complete SSB soft starter portfolio—Powerstarts, motor controllers, power modules, and communication gateways. We provide pan-India door-to-door pickup and delivery from all major cities including Mumbai, Delhi, Bangalore, Chennai, Hyderabad, Ahmedabad, Pune, and tier-2 industrial hubs. All repairs are done at our ISO-certified facility in Vadodara, Gujarat, with same-day fault diagnosis and typical 5-7 day turnaround.
What is the typical cost of SSB soft starter repair versus replacement?+
SSB soft starter repairs typically cost 40-60% of new unit price, depending on fault complexity and board-level work required. For example, a gate-drive or thyristor pack replacement runs 15,000-35,000 rupees versus 80,000+ for a new Powerstart. Synchronics provides upfront quotations after fault diagnosis and recommends repair if unit is less than 8-10 years old or if spare-parts cost is unavailable.
Can Synchronics handle SSB Profibus-integrated soft starters and PLC interface issues?+
Absolutely. SSB soft starters with Profibus gateway modules require specialized expertise in industrial protocol stacks. Synchronics engineers debug communication timeouts, reconfigure baudrate and node-address parameters, and reprogram protocol firmware. We validate repairs using Profibus master simulators to ensure seamless re-integration into your SCADA or PLC network without commissioning delays.
Do you test SSB soft starters under load before return?+
Yes. Every repaired SSB soft starter undergoes factory acceptance testing (FAT) including no-load voltage ramp validation, current-limit accuracy checks at 50%, 75%, and 100% motor ratings, over-voltage and thermal shutdown verification, and communication handshake testing for networked units. We provide a detailed test report with performance graphs for your maintenance records.
What warranty do you offer on SSB soft starter repairs?+
Synchronics offers 12 months repair warranty covering all component replacements and solder joints. If a repaired unit fails within warranty due to manufacturing defect or workmanship, we repair or replace free of charge. Extended 24-month warranties and spare-parts coverage are available for high-criticality motors in food plants, refineries, and continuous-process industries.
How do I send my SSB 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 SSB 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 SSB 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 SSB 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.
