Expert repairs for CR Magnetics transducers, sensors, and power monitoring systems.
CR MAGNETICS Product Lines We Repair
Our engineers are trained on the full CR MAGNETICS product range. Below are the major product families we service.
CR3000 / CR5000 Series Current Transducers
Split-core and solid-core current transducers with 0.5%-1% accuracy. Common faults include Hall sensor drift, output signal clipping, and zero-offset errors after thermal cycling or moisture ingress in outdoor installations.
CR Magnetics Voltage Transducers (CVM Series)
Isolated voltage measurement modules for single and three-phase systems. Repairs typically involve output amplifier failure, scaling errors, and isolation barrier degradation in high-humidity industrial settings.
CR Magnetics Power Quality Sensors (PQM Series)
Multi-channel integrated power quality monitoring and harmonic analysis modules. Frequent issues include individual channel signal loss, ADC conversion errors, and communication protocol faults on Modbus/Ethernet interfaces.
CR Magnetics Motor Protection Relay Modules
Current and thermal overload sensing modules for motor starter integration. Common failures stem from transducer calibration drift, relay contact welding, and nuisance trips due to sensor aging.
CR Magnetics Energy Metering Interface Modules
Precision energy accumulation and billing modules with CT/PT input conditioning. Issues include pulse output malfunction, register roll-over errors, and demand reset circuit failure in older installations.

Common CR MAGNETICS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CR MAGNETICS equipment arriving at our workshop.
- ✓Hall sensor output drift beyond tolerance band — Thermal aging of Hall IC in CR Magnetics transducers causes gradual bias shift. In hot climates (40-50°C ambient), coupled with industrial vibration stress, the sensor zero point drifts 2-5% annually, triggering high/low alarm thresholds.
- ✓Signal saturation or clipping in output stage — Excursions beyond rated current input to CR Magnetics transducers cause the secondary amplifier to reach supply rail limits. Common in Indian textile mills and steel plants where motor inrush currents exceed nameplate current by 8-10x during soft-starter or VFD commissioning.
- ✓Isolation barrier insulation breakdown — Moisture ingress in outdoor or marine-adjacent installations degrades the transformer coupling or optoisolator in CR Magnetics voltage transducers. Salt spray and monsoon damp storage cause creepage current leakage and eventual isolation failure.
- ✓Modbus RTU / Ethernet communication timeout errors — Firmware corruption or UART transceiver IC failure in CR Magnetics power quality and metering modules disrupts serial communication. Industrial EMI from welding equipment, motor soft-starters, and VFDs can corrupt the RS-485 transceiver on unshielded cable runs.
- ✓Relay contact welding or stiction on motor overload trips — Arcing at relay contacts in CR Magnetics motor protection modules during fault current interruption causes micro-welding. Vibration-induced chatter and moisture corrosion accelerate contact degradation, causing false overload lockouts.
- ✓Pulse output malfunction in energy metering modules — Opto-coupler LED degradation in CR Magnetics EMI series causes pulse width narrowing or complete loss of kWh pulse train. Extended operation above 50°C ambient or exposure to UV sunlight on panel-mounted units accelerates LED aging.

Frequently Asked Questions — CR MAGNETICS Repairs
Do you repair CR Magnetics equipment anywhere in India?+
Yes. Synchronics repairs the full CR Magnetics product range — current transducers, voltage sensors, power quality monitors, and motor protection relay modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and all other major cities. All repairs are performed at our main facility in Vadodara, Gujarat, with turnaround of 5-7 working days for most units.
My CR Magnetics current transducer shows erratic readings after monsoon storage. Can you fix it?+
Absolutely. Monsoon moisture ingress is a common issue in Indian industrial settings. Synchronics will open the transducer, dry the PCB under controlled humidity, clean corrosion on sensor pads, and re-solder any cold joints. We re-calibrate the Hall sensor output stage and conduct a full accuracy audit before return. Most moisture-damaged CR Magnetics units are fully recoverable.
What is the typical cost and turnaround for CR Magnetics repairs at Synchronics?+
CR Magnetics repair costs range from Rs 2,500 to Rs 8,000 depending on fault severity. Sensor recalibration and minor component replacement cost Rs 2,500-4,000. Major faults (isolation breakdown, relay contact welding) cost Rs 5,000-8,000. Standard turnaround is 5-7 days from receipt. Express service is available for critical textile mill and power station units at 10% premium.
Do you calibrate CR Magnetics transducers to original factory specs?+
Yes. Synchronics maintains precision current injection rigs and reference instruments traceable to national standards. We recalibrate CR Magnetics current transducers to ±0.5% accuracy across the rated input range, and voltage transducers to ±1% tolerance. A calibration certificate with before/after readings is provided with every repair.
Can you repair CR Magnetics power quality monitor modules with Ethernet interface?+
Yes. Synchronics repairs CR Magnetics CVM and PQM series modules including those with Ethernet, Modbus RTU, and RS-485 communication. We perform firmware re-flash, replace failed communication transceivers, and conduct protocol loop-back testing. If the Ethernet jack is damaged, we solder a replacement RJ45 connector and test all pinouts before shipment.
How do I send my CR MAGNETICS 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 CR MAGNETICS 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 CR MAGNETICS 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 CR MAGNETICS 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.
