CONTROLLED POWER Product Lines We Repair
Our engineers are trained on the full CONTROLLED POWER product range. Below are the major product families we service.
Controlled Power UPS 3000 Series
Three-phase modular UPS platform for medium-scale industrial and data centre applications. Common issues include rectifier module failures, DC bus capacitor degradation, and inverter IGBT faults causing under-voltage alarms and battery discharge anomalies.
Controlled Power StaticTransfer Switch (STS) Family
Fast-acting transfer mechanisms for redundant power paths in critical systems. Typical faults include contactor chatter, thyristor commutation failures, gate drive circuit malfunctions, and synchronization errors between primary and backup supplies.
Controlled Power Battery Management Module (BMM)
Intelligent charger-rectifier and battery monitoring unit for extended battery backup. Repair focuses on charging regulation failures, cell balancing circuit faults, temperature sensor drift, and firmware corruption in EEPROM.
Controlled Power Inverter Control Board (ICB)
DSP-based power stage modulation and feedback control. Common failures include PWM signal distortion, feedback amplifier saturation, reference voltage drift, and firmware hangs requiring JTAG re-flashing.
Controlled Power Rectifier Module Stack (RMS)
Thyristor or diode-based primary power conversion stage handling input harmonics and load transients. Repair addresses gating circuit delays, phase-shift errors, and thermal runaway in high-ambient environments common in Indian summer seasons.

Common CONTROLLED POWER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CONTROLLED POWER equipment arriving at our workshop.
- ✓Rectifier output voltage collapse under load — Thyristor gating circuit failure in Controlled Power rectifier modules causes loss of conduction angle control. High-temperature operation in Indian manufacturing plants accelerates capacitor ESR rise, reducing gate drive voltage margin and triggering cascade failures across phase legs.
- ✓Uninterrupted alarm despite stable DC bus voltage — Controlled Power UPS feedback sense circuit noise or reference drift causes false low-voltage detection. Common in plants with high VFD switching noise and inadequate isolation transformer grounding on incoming supply.
- ✓Static Transfer Switch chattering between sources — Controlled Power STS synchronization error or zero-crossing detector phase jitter under unbalanced three-phase supply conditions. Indian distribution networks often exhibit 5-15% voltage imbalance, aggravating sensing instability in critical load transfer moments.
- ✓Battery charger current limiting at 50% rated capacity — Controlled Power Battery Management Module temperature compensator or current sense amplifier saturation limits charging rate. Occurs in high-ambient Indian facilities (45-50C ambient not uncommon) where battery impedance increases and thermal derating activates prematurely.
- ✓Inverter output harmonic distortion > 8% THD — PWM modulation jitter in Controlled Power Inverter Control Board due to DSP firmware timing drift or feedback loop oscillation. Manifests under nonlinear loads (VFDs, switched-mode power supplies) common in Indian textile mills and semiconductor fabs.
- ✓Extended startup delay or fail-to-load condition — Controlled Power UPS firmware hangs during boot diagnostics due to corrupted EEPROM, failed RAM test, or SPI communication timeout with peripheral modules. Often triggered by sudden shutdown during firmware update or lightning surge transient.

Frequently Asked Questions — CONTROLLED POWER Repairs
Do you repair Controlled Power equipment anywhere in India?+
Yes. Synchronics repairs the complete Controlled Power portfolio — UPS systems (3000 Series and legacy models), Static Transfer Switches, Battery Management Modules, Inverter Control Boards, and Rectifier stacks. We offer door-to-door pickup and return across all Indian metros including Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and 500+ tier-2 industrial towns. Repair work happens at our flagship Vadodara, Gujarat facility with 72-hour standard turnaround.
Can you repair Controlled Power UPS units that have been discontinued?+
Absolutely. Synchronics maintains legacy component inventory and cross-reference expertise for older Controlled Power models no longer in production. We have reverse-engineered schematics for 1990s and 2000s-era units common in Indian textile mills and process plants. If original ICs are unavailable, we design and manufacture replacement control cards with identical form-factor and electrical interface. We have successfully refurbished Controlled Power units 15-20 years old.
What is the typical repair cost for a Controlled Power inverter board failure?+
Inverter Control Board repair cost ranges from Rs 8,000-25,000 depending on component failure extent and firmware complexity. Capacitor and optocoupler replacement is straightforward; DSP code corruption may require JTAG extraction and recompile services. Synchronics provides upfront quotation after bench diagnostics with 24-hour assessment turnaround. Many clients prefer board swap from our rental pool while repair is completed.
Do you offer preventive maintenance for Controlled Power UPS systems?+
Yes. Synchronics provides annual preventive maintenance (PM) contracts for Controlled Power installations. Our PM includes capacitor ESR trending, battery impedance profiling, rectifier diode leakage testing, and firmware audit against latest security patches. We schedule PMs during monsoon season (June-September) when Indian humidity and thermal stress peak. Quarterly capacitor thermography reports help predict failures 6-12 months in advance, minimizing surprise downtime.
What warranty do you provide on Controlled Power repairs?+
Synchronics offers 12-month parts replacement warranty and 6-month labour warranty on all Controlled Power repairs (excluding consumables like fans and batteries). Extended 24-month warranty is available at 15% surcharge for critical infrastructure clients. All warranty terms are subject to proper operational environment (ambient 0-50C, humidity 10-90% non-condensing) and compliance with Controlled Power load specifications.
How do I send my CONTROLLED POWER 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 CONTROLLED POWER 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 CONTROLLED POWER 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 CONTROLLED POWER 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.
