KB ELECTRONICS Equipment We Repair — By Category
KB ELECTRONICS Product Lines We Repair
Our engineers are trained on the full KB ELECTRONICS product range. Below are the major product families we service.
KBIC DC Drive Series
Solid-state DC motor speed controllers using SCR/thyristor technology. Common issues include thyristor short circuits, capacitor drying, logic board failures, and loss of speed regulation. These drives control textile machinery, hoists, winders, and pump applications across Indian industry.
KBL Soft Starter Series
AC motor soft starters for reduced inrush current and smooth torque ramp. Typical faults include gate driver failures, triac breakdown, control signal loss, and thermal shutdown errors. Widely used in Indian cement, sugar, and steel mills for motor protection.
KBDA AC Drive Series
Variable frequency AC motor drives for energy-efficient speed control. Common repair issues include phase loss detection faults, harmonic distortion problems, communication breakdowns, and heatsink thermal failures. Popular in Indian automotive, food processing, and HVAC applications.
KB Chassis Mount Controllers
Compact DC controller units for panel integration and retrofit applications. Prone to potentiometer drift, feedback circuit failures, and logic relay issues. Extensively used in Indian material handling, packaging, and textile machinery.

Common KB ELECTRONICS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in KB ELECTRONICS equipment arriving at our workshop.
- ✓KBIC thyristor gate drive failure and loss of drive output — Gate driver optocoupler failure or gate resistor open circuit due to age and heat cycling. The gate pulse train fails to fire thyristors, resulting in zero motor current and speed loss.
- ✓Electrolytic capacitor drying and DC bus voltage ripple — KB Electronics DC drives rely on large filter capacitors that dry out over 15-20 years due to continuous thermal stress. Reduced capacitance increases ripple, causing jerky motor motion and control instability.
- ✓KBL soft starter triac breakdown and phase dropout — Gate oxide degradation in triacs under heavy inrush current or repeated soft-start duty. One or more phases fail to conduct, creating single-phasing conditions and motor stalling.
- ✓Logic board control signal loss and erratic speed hunting — Cold solder joints on power and signal traces, or corroded connector pins from humidity exposure common in Indian coastal and humid industrial areas. Intermittent feedback loops cause speed oscillation.
- ✓Potentiometer wiper and sliding contact wear causing speed instability — Mechanical friction and electrical arcing over years of adjustment erode potentiometer tracks. Speed setpoint becomes noisy and non-repeatable, affecting production quality.
- ✓Thermal shutdown nuisance trip without actual overtemp condition — Thermistor thermal contact loss due to corrosion or mounting looseness, or comparator circuit drift in the thermal sensing module. Drive trips intermittently despite normal heatsink temperature.

Frequently Asked Questions — KB ELECTRONICS Repairs
Do you repair KB Electronics equipment anywhere in India?+
Yes. Synchronics repairs the full KB Electronics product range — KBIC DC drives, KBL soft starters, KBDA AC drives, and all control modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Indore, and 100+ other cities. Single repair facility in Vadodara, Gujarat with 30+ years of KB Electronics expertise.
What is the typical repair turnaround for KB KBIC drives in India?+
Most KBIC DC drive repairs are completed in 3-5 working days after receipt. Priority urgent repairs can be turned around in 24-48 hours. Synchronics maintains stock of common replacement modules — thyristor cards, gate driver boards, and capacitor assemblies — to minimise repair time. We also provide on-site commissioning and speed calibration after repair.
How do I know if my KB soft starter has a triac failure versus a control board problem?+
KB soft starters showing single-phase motor operation, humming without speed ramp, or repeated thermal trips usually have triac gate drive or control circuit faults. Synchronics uses curve-tracer testing to isolate failed triacs from control board failures. We provide detailed fault reports identifying exact component failures, spare parts required, and repair cost before starting work.
Can Synchronics repair KB KBIC drives with custom potentiometer calibrations for my specific application?+
Yes. We repair and recalibrate KB KBIC drives to match your original setpoint range — whether 0-100 RPM for winding applications or 0-3000 RPM for pump duty. Synchronics documents the calibration curve and provides a commissioning certificate. We also advise on upgrading older KBIC models to newer KBL or KBDA platforms for improved efficiency and reliability.
What warranty do you provide on KB Electronics drive repairs?+
Synchronics provides 12 months comprehensive warranty on all repaired KB Electronics equipment covering components and labour. Warranty covers field failures resulting from repair workmanship, not application abuse or damage. We also offer extended 24-month warranty options for critical production lines.
How do I send my KB ELECTRONICS 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 KB ELECTRONICS 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 KB ELECTRONICS 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 KB ELECTRONICS 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.
