ABSOPULSE Product Lines We Repair
Our engineers are trained on the full ABSOPULSE product range. Below are the major product families we service.
DCX Series DC Converters
High-efficiency modular DC-to-DC converters with redundancy capability. Common issues include input overvoltage crowbar trips, output voltage droop under load, and module communication failures.
Battery Charger Modules
Three-stage intelligent chargers with float and equalize modes for sealed lead-acid and lithium batteries. Failures include faulty charge profile detection, temperature compensation sensor drift, and relay contactor burnout.
Redundancy Controllers
Hot-standby and load-sharing logic modules for parallel DC power systems. Typical faults: diode bridge reverse-bias failures, load-share voltage feedback loop instability, and watchdog timeout errors.
Auxiliary Power Controllers
Compact switched-mode supplies for telecom and automation racks. Common problems: primary side MOSFET failures, secondary rectifier diode short circuits, and output voltage sense line disconnection.
Uninterruptible Power Supply (UPS) Modules
Sealed-case UPS systems for critical telemetry and SCADA equipment. Issues include battery management module firmware corruption, AC/DC input selector relay failure, and charger circuit board corrosion.
Surge Suppression and Filtering
Input conditioning and EMI filtering for harsh industrial environments. Repair needs: varistor degradation, filter capacitor ripple current failure, and surge threshold drift.

Common ABSOPULSE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ABSOPULSE equipment arriving at our workshop.
- ✓Output voltage regulation loss or drift — Absopulse converters regulate via feedback from internal sense resistors or external sense lines. Degraded feedback capacitors, broken sense wire connections, or OpAmp feedback network component drift causes slow voltage rise or sagging output. Temperature cycling and vibration are primary failure drivers in Indian industrial environments.
- ✓Crowbar overvoltage shutdown triggering intermittently — Absopulse modules include input crowbar circuits that clamp excessive voltage to ground via SCR. Defective voltage monitoring ICs, faulty comparator circuits, or degraded threshold setting resistors cause nuisance crowbar trips — halting output even when input is within range. This is especially common in older DCX converters with aging electrolytic capacitors.
- ✓Battery charger module not entering float mode — Absopulse battery chargers transition from bulk to float mode when battery voltage reaches setpoint. Faulty charge voltage sense circuits, stuck relay contactors, or corrupted three-stage timing logic prevent transition — causing continuous overcharging and battery gas evolution. Thermal sensor faults also lock chargers in constant-current mode.
- ✓Redundancy load-sharing diodes reverse-conducting — Absopulse redundancy modules use high-current diodes in the OR-ing network to allow multiple converters to feed one load. Reverse voltage spikes during transient load steps, solder cracks, or manufacturing defects cause diode forward conduction even when reverse-biased — shunting current through unintended paths and creating hot spots.
- ✓Watchdog timeout causing module reset loops — Modern Absopulse controllers embed watchdog timers to detect firmware hangs or oscillator clock loss. Software bugs, corrupted flash memory, or intermittent clock reference failures trigger repeated watchdog resets — preventing stable operation. This is often aggravated by EMI in close proximity to drives or high-frequency switching equipment.
- ✓Filter capacitor ripple current failure or explosion — Absopulse modules carry large DC currents through electrolytic filter capacitors rated for specific ripple current envelopes. Inadequate thermal dissipation in closed cabinets, undersized heat sinks, or ambient temperature near rating limits cause capacitor core temperature rise. High ESR and electrolyte evaporation lead to pressure build-up and eventual failure or catastrophic rupture.

Frequently Asked Questions — ABSOPULSE Repairs
Do you repair Absopulse equipment throughout India?+
Yes. Synchronics Electronics is authorised to repair all Absopulse DC power conversion, charger, and redundancy controller modules across India. We offer door pickup from major cities — Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and beyond. All repairs are performed in our Vadodara facility using factory-equivalent diagnostics and original components. Turnaround time is typically 5-8 working days.
What is the most common fault in Absopulse DCX series converters installed in India?+
Output voltage droop under load is the most frequent issue we see in DCX series converters deployed in Indian plants. This occurs when feedback capacitors degrade due to heat cycling in non-air-conditioned equipment rooms, or when sense wires vibrate loose on shop floors. Synchronics diagnoses this via real-time oscilloscope capture and load testing, then replaces feedback networks and re-trims voltage setpoints to Absopulse factory specs.
Can Synchronics repair Absopulse battery charger modules without sending the entire cabinet?+
Absolutely. Absopulse charger modules are modular by design. You can safely remove the failed unit (after isolating DC rails and de-energising the cabinet) and ship only the charger module to Synchronics. We test, repair, and return it with a comprehensive test report. For urgent outages, we can offer a loaner unit while your module is being repaired.
Do you stock Absopulse replacement components and modules?+
Yes. Synchronics maintains a stock of common Absopulse components including high-reliability electrolytics, MOSFETs, control ICs, and diode packs. We also stock refurbished Absopulse charger and converter modules for rapid emergency swap-outs during extended repairs. Contact our sales team for emergency stock availability and lead times.
How do I know if my Absopulse module has failed versus a downstream load issue?+
Synchronics provides free diagnostic consultation. Use a multimeter to check output voltage under no-load and with known safe load. If voltage is absent or unstable, isolate the Absopulse module and ship it to us. We perform bench testing with programmable load banks and measure all internal voltages, thermal response, and ripple. You receive a detailed fault report with repair cost estimate.
How do I send my ABSOPULSE 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 ABSOPULSE 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 ABSOPULSE 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 ABSOPULSE 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.
