LEM DynAmp Equipment We Repair — By Category
LEM DynAmp Product Lines We Repair
Our engineers are trained on the full LEM DynAmp product range. Below are the major product families we service.
LEM DynAmp Current Transducers
Hall-effect based AC and DC current measurement modules used in variable frequency drives and motor control systems. Common failures include zero-offset drift, bandwidth reduction, and output signal loss due to thermal stress or sensor contamination in dusty plant environments.
LEM Power Amplification Modules
Isolated gate drive and signal conditioning units that amplify weak sensor outputs for PLC and DSP inputs. Typical faults include amplifier saturation, phase shift errors, and isolation barrier breakdown under transient electrical stress.
LEM DynAmp Voltage Measurement Boards
Differential voltage sensing and analog-to-digital conversion modules for DC bus and AC mains monitoring in industrial drives. Failures often stem from precision resistor network degradation and operational amplifier offset errors after prolonged thermal cycling.
LEM Signal Conditioning Electronics
Precision low-noise preamplifiers and active filtering stages for weak analog signals in sensitive control loops. Common issues include capacitor leakage, filter instability, and frequency response distortion in electrically noisy factory floors.
LEM DynAmp Isolated Interface Modules
Optical or magnetic isolation barrier stages protecting sensitive measurement circuits from high common-mode voltage transients in motor drives and power conversion systems. Degradation of isolation characteristics and timing skew are frequent failure modes.

Common LEM DynAmp Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in LEM DynAmp equipment arriving at our workshop.
- ✓Zero offset drift in current transducer output — Thermal cycling and aging of Hall-effect sensor semiconductors in LEM DynAmp transducers cause baseline zero-point error to increase over 2-5 years, especially in furnace halls and foundries where ambient temperature swings from 15°C to 60°C daily.
- ✓Loss of signal output or amplitude reduction — LEM DynAmp amplifier stages suffer from capacitor dry-out and OpAmp input offset voltage drift when exposed to high-humidity cotton mill environments or inadequate panel ventilation. Printed circuit board traces corrode, increasing contact resistance.
- ✓Bandwidth collapse or signal filtering artifacts — Precision resistor-capacitor networks in LEM DynAmp signal conditioning modules drift due to component aging and solder joint microcracking under vibration, shifting filter corner frequencies and introducing phase distortion into motor drive feedback loops.
- ✓Isolation barrier failure or leakage current increase — Optical couplers and isolation transformers in LEM DynAmp isolated interface modules degrade when subject to sustained DC offset bias and supply voltage transients from adjacent welding or induction heating equipment in Indian job shops.
- ✓Intermittent fault codes or erratic sensor readings — Connector corrosion, cold solder joints, and PCB microfractures in LEM DynAmp transducers cause intermittent open circuits, particularly when modules are mounted on vibrating motor frames or exposed to salt-air environments in coastal Indian industrial zones.
- ✓Unreliable measurement under high dynamic current transients — Slew rate limitations and input stage saturation in aging LEM DynAmp amplifiers cause measurement lag and false peak detection in high-speed servo control and induction motor soft-start applications drawing transient currents exceeding 10 kA/sec.

Frequently Asked Questions — LEM DynAmp Repairs
Do you repair LEM DynAmp equipment anywhere in India?+
Yes. Synchronics Electronics repairs the full LEM DynAmp product range - current transducers, power amplification modules, voltage measurement boards, and signal conditioning electronics. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other major cities. All repairs are handled at our ISO 9001 certified facility in Vadodara, Gujarat, with typical turnaround of 7-10 working days.
What LEM DynAmp products does Synchronics repair?+
Synchronics specializes in repairing LEM DynAmp current transducers (P500, P1000, P2000 series), isolated power amplification modules, voltage measurement and conditioning boards, and signal isolation interface stages. We handle single-point failures like capacitor aging and catastrophic faults such as isolation barrier breakdown. Each repair includes full recalibration and functional testing against original LEM performance specifications.
How much does LEM DynAmp repair cost, and how long does it take?+
LEM DynAmp repair costs range from INR 4,000 to 18,000 depending on fault severity and component replacement needs. Simple recalibration takes 3-4 working days; complex transducer re-specification takes 7-10 days. We provide free diagnostic assessment and written quotation within 24 hours of receiving your module. Rush turnaround (48 hours) is available on request at 20% premium.
Why does my LEM DynAmp current transducer show zero drift in summer?+
Hall-effect sensors in LEM DynAmp transducers exhibit temperature coefficient of offset of roughly 0.5 mV/°C. In Indian summers, when ambient temperature rises from 25°C to 45°C, zero offset can drift 10 mV or more, causing measurement errors in soft-starters and VFDs. Synchronics recalibrates the offset compensation network using temperature-stable reference sources to eliminate seasonal drift.
Can you repair LEM DynAmp modules with custom modifications or non-standard configuration?+
Yes. Synchronics has experience modifying LEM DynAmp amplifier gain stages, re-ranging measurement scales, and adapting interface connectors for integration with legacy Indian PLC systems from Siemens, Allen-Bradley, and Schneider. We document all modifications and provide application notes. Charges vary based on complexity; contact our technical team for quotation.
How do I send my LEM DynAmp 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 LEM DynAmp 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 LEM DynAmp 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 LEM DynAmp 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.
