ELTEK ENERGY Product Lines We Repair
Our engineers are trained on the full ELTEK ENERGY product range. Below are the major product families we service.
FLATPACK Series (Rectifiers & Converters)
Industrial rectifier modules and DC power supplies for telecommunications, data centres, and grid applications. Common issues include thermal management failures, capacitor degradation, and control circuit faults in high-load environments.
Distributed Power Systems (DPS)
Modular DC power distribution platforms for large-scale industrial and telecom installations. Repair focus: communication board failures, redundancy module faults, and power distribution unit synchronization issues.
SMPS Industrial Power Supplies
Switched-mode power supplies for manufacturing automation, process control, and industrial equipment. Typical faults include transformer saturation, MOSFET burnout, and protection circuit malfunction under load spike conditions.
Battery Management & Chargers
Advanced battery backup systems and smart chargers for UPS, telecom, and energy storage applications. Common repairs address voltage regulation drift, charging cycle logic errors, and cell balancing circuit faults.
Renewable Energy Converters
DC-DC and AC-DC converters designed for solar, wind, and microgrid integration in Indian industrial and utility projects. Failures often involve MPPT control loss, isolation transformer issues, and grid synchronization faults.
Telecom-Grade Rectifier Modules
High-reliability 48V and 24V DC rectifiers for Indian telecom towers, base stations, and communication infrastructure. Repair expertise includes thyristor control faults, communication protocol failures, and redundant module synchronization.

Common ELTEK ENERGY Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ELTEK ENERGY equipment arriving at our workshop.
- ✓Thermal shutdown and continuous overload protection trips — ELTEK power supplies incorporate intelligent thermal management. Failures occur due to heatsink fouling in industrial dust environments, fan bearing degradation, or thermal sensor calibration drift common in Indian manufacturing plants operating in high ambient temperatures.
- ✓Output voltage regulation failure and voltage drift — ELTEK rectifiers use precision feedback networks and opto-isolator circuits. Electrolytic capacitor aging, feedback resistor tolerance drift, or opto-coupler LED degradation — prevalent in India's high-humidity and temperature-cycled industrial settings — cause regulation failure.
- ✓Loss of redundancy synchronization between parallel modules — ELTEK's DPS and Flatpack systems use current-sharing control circuits. Communication line faults, DSP firmware corruption, or phase-lock loop instability in the synchronization control module cause redundancy loss, risking uneven load distribution and module failure.
- ✓Battery charger output low or no charging current — ELTEK chargers employ PWM control and precision current-sense amplifiers. Failures stem from PWM driver IC malfunction, current-sense resistor open circuit, or control feedback loop instability — common after extended operation in Indian telecom installations.
- ✓AC input line filter instability and EMI suppression loss — ELTEK industrial supplies use LC input filters and varistors for EMI compliance. Filter inductor saturation, varistor element failure from surge events, or capacitor dielectric breakdown — typical in Indian facilities with unreliable grid and frequent transients — cause input instability.
- ✓Communication and control interface malfunction (RS-485, CAN, Modbus) — ELTEK's networked power systems use isolated serial interfaces. Isolation transformer failure, transceiver IC damage from voltage transients, or firmware corruption in the communication stack cause interface loss — common in multi-unit parallel configurations.
