AMREL Product Lines We Repair
Our engineers are trained on the full AMREL product range. Below are the major product families we service.
AMREL Programmable DC Power Supplies
High-performance modular DC supplies ranging 5-500V output with current capabilities up to 2000A. Common failures include capacitor dry-out in input filter stages, PWM control board faults, and remote-sense line degradation. Indian high-altitude and temperature-sensitive test labs experience thermal stress failures in humid monsoon climates.
AMREL Electronic Programmable Loads
Bidirectional electronic load systems for power supply testing and battery validation. Common faults: FET output stage failures under high dissipation transients, RS-232/CAN interface board corruption, and front-panel LCD display burnout. AMREL loads operate in Indian battery manufacturing and telecom backup power validation.
AMREL DC-DC Converter Modules
Sealed military-grade and industrial DC-DC isolated converters with integrated magnetics. Repair issues: potted module internal transformer breakdown, output regulation drift on 48V and 28V aerospace rails, and capacitor stack failures due to thermal cycling in Indian outdoor industrial installations.
AMREL Redundancy Modules and Power Sequencers
Master-slave control cards for multi-unit parallel operation and coordinated power sequencing in critical systems. Failures include relay contact erosion on cross-current detection, microcontroller firmware corruption, and opto-isolator degradation in Indian telecommunications central offices and data centres.
AMREL Remote Monitoring and Interface Modules
Ethernet, GPIB, and analog-output interface cards enabling distributed load sharing and plant SCADA integration. Common faults: Ethernet transceiver burnout from surge, RS-485 isolation barrier breakdown, and firmware update hang on aged equipment in Indian manufacturing networked environments.
AMREL Aerospace-Grade Power Supplies
DO-160G and ARP-4754A certified supplies for avionics test benches and in-flight emergency power systems used by Indian aerospace OEMs and defence contractors. Failures: secondary winding insulation breakdown on isolated outputs, crowbar protection circuit nuisance trips, and aging Schottky diodes in rectifier stages.

Common AMREL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AMREL equipment arriving at our workshop.
- ✓Output voltage regulation drift and ripple increase — AMREL supplies use aging electrolytic capacitors (input bulk, output filter, feedback network) that dry out in Indian industrial heat and humidity. Equivalent series resistance increases, reducing feedback network precision and boosting output ripple. Temperature cycling in non-air-conditioned test bays accelerates degradation.
- ✓Intermittent shutdown and restart on load step — AMREL PWM control modules suffer degraded thermal coupling to heatsinks in dusty industrial environments. Overtemperature sensing becomes intermittent; the processor shuts down momentarily during load transients. Dust buildup and inadequate cooling airflow are endemic in Indian foundries and textile mills using AMREL supplies.
- ✓No output voltage and power-on indicator lamp dark — AMREL bulk input capacitors (100-470uF, 400V rated) suffer internal short-circuit in high-humidity Indian monsoon regions. The inrush current limiter (NTC thermistor or series resistor) fails, drawing excessive startup current. Blown input fuses and tripped AC breakers cascade from this single point of failure.
- ✓Remote sense lead open circuit—voltage regulation loss — AMREL supplies use thin twisted-pair remote sense leads (typically 26AWG) routed across high-current bus bars and motor starters in Indian factory floors. Vibration, electromagnetic coupling from adjacent induction motors, and corrosion in humid coastal facilities (Mumbai, Chennai ports) break the sense connection. The supply regulates at the supply terminals, not the load.
- ✓Electronic load FET output stage fails—smoke and odour — AMREL electronic loads (LOAD300-10 series) use MOSFET output stages rated for sustained 10A at 300V. In Indian battery manufacturing test lines, repetitive duty cycles and inadequate heat-sink cooling cause junction temperature runaway. Drain-source avalanche during load transient turnoff destroys the FET gate oxide; catastrophic failure follows within milliseconds.
- ✓Redundancy module cross-current relay sticks—parallel supply conflict — AMREL redundancy modules use dual relays (one per supply) to detect and isolate cross-current when master and standby units are paralleled. Relay contact erosion from arcing during transient load steps causes intermittent sticking. Indian data centres running 24x7 parallel supplies experience voltage oscillations and nuisance disconnections.

Frequently Asked Questions — AMREL Repairs
Do you repair AMREL equipment anywhere in India?+
Yes. Synchronics repairs the full AMREL product range—programmable DC power supplies, electronic loads, DC-DC converters, redundancy modules, and interface cards. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Indore, Jaipur, and all other cities. All repairs are completed in our facility in Vadodara, Gujarat. We provide prepaid courier logistics and insured shipping.
Why do AMREL power supplies fail more often in Indian monsoon climates?+
AMREL supplies use electrolytic capacitors and sealed relays that are sensitive to humidity and temperature cycling. Indian coastal and tropical climates (Mumbai, Chennai, Kolkata, Bangalore monsoons) cause accelerated capacitor dry-out and relay contact corrosion. Synchronics mitigates this by replacing capacitors with 105C-rated types and applying moisture-resistant coatings to relay contacts. We also advise customers on ventilation and thermal management for non-air-conditioned Indian factory floors.
Can you repair AMREL electronic load equipment with burnt-out FET stages?+
Yes. AMREL electronic loads (LOAD300 series and higher) frequently suffer FET output stage failures due to thermal stress and transient overvoltage. Synchronics replaces the FET stage with military-grade equivalents rated for higher safe operating area (SOA), installs fresh thermal interface material, and conducts dynamic load-dump testing (500us edge transients) to confirm ruggedness. We provide SOA test curves and reliability documentation specific to Indian industrial duty cycles.
Do you calibrate AMREL power supplies after repair?+
Yes, calibration is standard for all AMREL power supply repairs. Synchronics uses precision DC meters (0.1% accuracy, 5-digit display) to verify output voltage accuracy, load regulation, line regulation, and ripple performance across the full output range and temperature. We conduct verification testing at ambient room temperature and provide a calibration certificate. For critical aerospace or pharmaceutical applications, we offer thermal chamber validation (-10C to +60C) and cross-load testing on request.
How long does AMREL power supply repair typically take?+
Standard AMREL repairs (capacitor replacement, control board diagnostics, output regulation tuning) typically take 5-7 working days in Synchronics' Vadodara facility. Rush service (same-day diagnostics, 2-3 day turnaround) is available for critical Indian manufacturing and telecom operations. We provide phone and email updates every 24 hours. Complex power converter or aerospace supply repairs may require 10-14 days with full thermal and load validation.
How do I send my AMREL 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 AMREL 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 AMREL 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 AMREL 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.
