TDK-LAMBDA Equipment We Repair — By Category
TDK-LAMBDA Product Lines We Repair
Our engineers are trained on the full TDK-LAMBDA product range. Below are the major product families we service.
ZWS Series - Programmable Power Supplies
High-performance programmable power supplies featuring multiple output channels and remote programming capability. Common failures include capacitor degradation, thermal management issues, and control board faults leading to unstable voltage output or complete shutdown.
ZUS Series - Industrial AC-DC Supplies
Robust single and dual output AC-DC supplies designed for continuous industrial operation. Typical repair issues involve rectifier bridge failures, transformer winding faults, and output regulation problems under load fluctuation.
ZPAC Series - Compact Enclosed Power Supplies
Compact modular power supply units for space-constrained installations in control panels and automation systems. Common failures include fan motor burnout, input filter degradation, and internal connector corrosion in humid Indian manufacturing environments.
GEN Series - Regulated Power Supplies
Linear and switching regulated power supplies with high stability specifications for laboratory and production testing. Repair typically addresses voltage regulation drift, ripple exceeding specifications, and thermal runaway conditions.
DRB Series - DC-DC Converters
High-density DC-DC converter modules for distributed power architecture in industrial control systems. Failures commonly stem from input capacitor aging, magnetic component saturation, and secondary side rectifier diode failures.
MDP Series - Modular Power Supplies
Modular redundant power supply systems for mission-critical industrial applications requiring N+1 redundancy. Typical issues involve module mismatch, current sharing circuit faults, and hot-swap connector degradation.

Common TDK-LAMBDA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in TDK-LAMBDA equipment arriving at our workshop.
- ✓Output voltage out of specification or unstable — Feedback network resistor drift, PWM controller IC degradation, or electrolytic capacitor ESR rise in TDK-Lambda ZWS/ZUS units exposed to high ambient temperatures common in Indian manufacturing plants. Age and thermal cycling accelerate component fatigue.
- ✓Complete power supply shutdown or no output — Input rectifier bridge failure, primary side fuse blowing due to transient surge, or transformer primary winding short in TDK-Lambda ZPAC/GEN series. Indian power grid voltage surges and poor earthing in older plants are contributing factors.
- ✓Excessive output ripple or noise exceeding specifications — Output filter capacitor failure, weak or damaged filter inductors, or PWM switching frequency drift in TDK-Lambda ZWS units. Mechanical vibration from nearby machinery can cause solder joint failures at filter connections.
- ✓Fan noise or fan failure leading to thermal shutdown — Bearing wear in brushless fan motors, thermal cutout triggering due to dust accumulation on heatsinks, or thermal sensor malfunction in TDK-Lambda compact ZPAC and MDP series units. Indian industrial environments with high dust exposure accelerate wear.
- ✓Intermittent operation or erratic voltage output — Micro-cracks in solder joints on control boards, loose internal connectors, or intermittent IC contact issues in TDK-Lambda ZUS and ZPAC series. Vibration from industrial machinery and thermal expansion cycling cause these failures.
- ✓Overvoltage or overcurrent protection not engaging — Protection circuit comparator IC failure, sense resistor drift, or soft-start charging circuit malfunction in TDK-Lambda programmable units (ZWS series). Failed protection leaves connected equipment vulnerable to damage.

What is the typical turnaround time for TDK-Lambda ZWS programmable power supply repair?+
TDK-Lambda ZWS series repairs typically take 5-7 working days from receipt at our Vadodara facility. This includes detailed diagnostics using precision instruments, component-level repair or replacement, recalibration against TDK-Lambda specifications, and full-load testing. Urgent priority repairs can be completed in 48-72 hours for critical production scenarios. We provide status updates and expedited shipping for time-sensitive applications.
Can Synchronics repair TDK-Lambda power supplies with burnt components or water damage?+
Yes. Synchronics has extensive experience repairing TDK-Lambda units with component burn damage, corrosion, and moisture ingress common in humid Indian factory environments. We perform full board cleaning, micro-component replacement, PCB trace repair, and conformal coating application. However, repair feasibility depends on damage extent. We provide free diagnostic assessment and quote within 48 hours. Severely damaged boards may require replacement, which we source as OEM alternatives or refurbished units at competitive rates.
Do you provide warranty on TDK-Lambda power supply repairs?+
Yes. All Synchronics repairs on TDK-Lambda equipment come with a 12-month comprehensive warranty covering component failure and performance degradation under normal operating conditions. The warranty covers labour, parts, and repeat repairs for the same fault. Extended warranty options up to 36 months are available for mission-critical systems. Warranty terms require proper maintenance and operation within TDK-Lambda specifications.
What documentation do I need to send with my TDK-Lambda power supply for repair?+
Send the unit with original model/serial number plate, any error codes or symptom logs, and documentation of the failure mode. If available, send the original datasheet and application manual. This helps our engineers diagnose faster. We maintain detailed repair records for each unit, including pre-repair diagnostics, replaced components, recalibration data, and post-repair test reports — all provided with your repaired equipment for future reference and maintenance planning.
How do I send my TDK-LAMBDA 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 TDK-LAMBDA 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 TDK-LAMBDA 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 TDK-LAMBDA 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.
