CWT Product Lines We Repair
Our engineers are trained on the full CWT product range. Below are the major product families we service.
CWT Server & Data Centre PSUs
High-efficiency 1U/2U rack-mount power supplies rated 500W–3000W for servers, storage arrays, and networking equipment. Common faults include tantalum capacitor failures, PWM controller burnout, and fan bearing seizure under sustained load.
CWT Industrial 48V Distributed Power Systems
Multi-rail 48VDC supplies for telecom base stations, industrial automation controllers, and edge computing nodes. Repair typically addresses isolated DC-DC module failure, bias supply collapse, and control loop instability.
CWT LED Driver Modules
Constant-current and constant-voltage drivers for industrial LED arrays, architectural lighting, and machine vision systems. Failures commonly stem from MOSFET gate-drive faults, PWM frequency drift, and thermal sensor malfunction.
CWT Embedded & Custom Power Modules
OEM-integrated power conversion modules for PLC enclosures, motion controllers, and industrial frequency converters. Repair scope includes transformer winding continuity, primary-to-secondary isolation breakdown, and output regulation drift.
CWT ATX & Compact Form-Factor PSUs
Desktop and compact industrial PC power supplies (300W–600W) used in HMI systems, edge processors, and kiosk terminals. Common issues include aging polymer capacitors, thermal throttling, and secondary rail sag under heavy load.

Common CWT Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CWT equipment arriving at our workshop.
- ✓Tantalum capacitor degradation and catastrophic failure — CWT server PSUs employ tantalum bulk capacitors in primary stages. Under sustained high-ambient-temperature operation (40°C+) common in Indian data centres without adequate cooling, these capacitors dry out and short, drawing excessive current through the rectifier bridge and control transformer.
- ✓PWM controller IC lockup and no-output condition — CWT designs use primary-side PWM controllers (e.g. UC3844, TL494 variants) that fail when auxiliary winding feedback becomes unstable or primary-side capacitor ESR exceeds limits. This is exacerbated by noisy Indian industrial mains (brown-outs, harmonics, phase imbalance).
- ✓48V distributed power system isolated DC-DC module failure — CWT R48V series employ isolated buck-buck topologies in sub-modules. Failure occurs when the transformer feedback winding opens or the isolated PWM driver photocoupler ages, cutting off gate drive to the secondary MOSFET and causing zero output from that rail.
- ✓LED driver MOSFET gate-drive collapse and dimming — CWT LED drivers use bootstrap-fed gate drivers for high-side MOSFETs. If the bootstrap capacitor ages or the gate-drive transformer saturates, the high-side MOSFET undershoots, causing poor switching efficiency, excessive heat dissipation, and loss of brightness control authority.
- ✓Thermal sensor malfunction and uncontrolled fan speed — CWT server PSUs include NTC thermistor-based thermal monitoring connected to a microcontroller-driven fan circuit. If the thermistor becomes disconnected, reads out-of-range, or the firmware limits are corrupted, the fan runs at maximum speed or not at all, causing thermal runaway or acoustic nuisance.
- ✓Secondary-side output voltage regulation loss under heavy transient load — CWT designs rely on secondary-side feedback networks and synchronous rectifier gate drives to maintain tight 5V/3.3V/12V output regulation. In Indian industrial environments with rapid load step changes (servo drive activation, inrush currents), feedback capacitors ESR rise or the loop compensation becomes underdamped, causing overshoot and oscillation.

Frequently Asked Questions — CWT Repairs
Do you repair CWT equipment anywhere in India?+
Yes. Synchronics is the authorised service partner for CWT power supplies, LED drivers, and embedded modules across India. We offer PAN India door-step pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Jaipur, and all tier-1/tier-2 cities. All repairs are performed in our fully-equipped Vadodara, Gujarat facility and returned within 5–10 working days.
What is the warranty on CWT repairs at Synchronics?+
All CWT repairs come with a 12-month comprehensive warranty covering parts, labour, and testing. We issue an independent test certificate with load-test waveforms, thermal performance data, and compliance with original CWT specifications. Extended warranties and preventive maintenance contracts are available for data centre and telecom operators.
Can you repair CWT server PSUs with burnt or shorted tantalum capacitors?+
Absolutely. Tantalum capacitor failure is one of the most common CWT server PSU faults in India's hot, dusty climate. Our engineers perform full circuit analysis, replace the entire tantalum bank with high-reliability polymer alternatives, and recalibrate the control loop. We also recommend input-stage filtering upgrades to extend supply life in noisy grid environments.
Do you stock CWT replacement parts and modules?+
Yes. Synchronics maintains a comprehensive stock of CWT power modules, isolated DC-DC converters, PWM controllers, thermal management components, and high-reliability capacitors suitable for server and industrial applications. Emergency next-day component delivery is available for critical data centre outages across major Indian metros.
How do I know if my CWT PSU or LED driver needs repair versus replacement?+
Contact Synchronics for a free diagnostic assessment. We perform non-invasive electrical and thermal testing, measure capacitor ESR, test all output rails under load, and provide a written repair recommendation with cost estimate. For CWT equipment under 5 years old with single-point failures (controller IC, capacitor, MOSFET), repair is almost always more economical than replacement. Critical data centre supplies are repaired and hot-swapped to minimise downtime.
How do I send my CWT 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 CWT 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 CWT 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 CWT 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.
