COUGAR Product Lines We Repair
Our engineers are trained on the full COUGAR product range. Below are the major product families we service.
Cougar Uninterruptible Power Supply (UPS) Series
Industrial-grade UPS systems ranging from 500VA to 20kVA, featuring online double-conversion topology and automatic voltage regulation. Common faults include battery charging circuit failures, inverter MOSFET degradation, and static bypass switch malfunctions under load transients.
Cougar Industrial Power Supply (IPS) Range
Regulated DC power supplies (24V, 48V, 110V output) designed for automation and control circuits in factory environments. Prone to input rectifier failures due to voltage transients on Indian industrial grids, thermal runaway in integrated heatsinks, and control loop oscillation.
Cougar Programmable Logic Controller (PLC) Series
Compact and modular PLC systems for machinery automation, production line control, and equipment sequencing. Frequent issues include corrupted program memory, I/O module relay contact wear, real-time clock battery depletion, and communication protocol stack failures on RS-485 networks.
Cougar Power Factor Correction (PFC) Modules
Harmonic distortion reduction and reactive power compensation devices for multi-motor industrial plants. Common failures include capacitor bank degradation from heat stress, thyristor gate drive circuit faults, and triggering circuit instability during load fluctuations.
Cougar Human-Machine Interface (HMI) Touch Panels
Industrial touchscreen controllers (4-inch to 15-inch displays) for real-time process visualization and parameter adjustment. Typical repairs involve LCD backlight failure, capacitive touch sensor degradation, Ethernet port corrosion, and firmware flash memory errors.
Cougar Servo Drive and Motion Control Cards
Stepping motor drivers and servo amplifiers for precision positioning in packaging, printing, and textile machinery. Failure modes include PWM bridge IGBT failures, encoder signal loss, feedback loop instability, and thermal sensor malfunctions under continuous duty.

Common COUGAR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in COUGAR equipment arriving at our workshop.
- ✓Cougar UPS battery charging circuit malfunction — Constant-voltage/constant-current (CC/CV) control loop instability caused by aged electrolytic capacitors in the feedback network, or blown charge controller MOSFET due to lightning transient overvoltage during monsoon season electrical surges common in Indian industrial areas.
- ✓Cougar IPS 24V/48V rail under-voltage with overcurrent shutdown — Input rectifier diodes experiencing secondary breakdown due to repetitive grid voltage spikes on Indian industrial power lines (common in textile mills and foundries), or control circuit regulation MOSFET gate drive circuit damaged by AC coupling capacitor leakage current.
- ✓Cougar PLC program memory corruption with watchdog reset loop — Corrupted EEPROM flash blocks causing checksum errors during bootup, typically triggered by power loss during write cycles or by electromagnetic interference from adjacent motor starters and frequency converters in high-noise factory environments.
- ✓Cougar HMI touchscreen panel no display or partial pixels — LCD backlight CCFL lamp age-related dimming reaching zero light output (typical at 50,000+ hours in hot humid climates), or cold-solder joints in LVDS (Low-Voltage Differential Signaling) connector from thermal cycling between indoor and outdoor machinery cabinet environments.
- ✓Cougar servo drive IGBT bridge shoot-through with phase-leg short circuit — Gate drive signal timing skew or dead-time circuit malfunction causing simultaneous conduction of high-side and low-side IGBTs, often triggered by PWM control signal noise interference from nearby 400V three-phase wiring or damaged isolation resistor networks.
- ✓Cougar PFC module thyristor gate drive failure with reactive power loss — Optocoupler LED degradation in gate drive circuit due to prolonged operation in high-ambient temperature machinery rooms (common in Indian sugar mills and foundries), or faulty zero-crossing detector IC losing synchronization with AC mains phase angle.

Frequently Asked Questions — COUGAR Repairs
Do you repair Cougar equipment anywhere in India?+
Yes. Synchronics repairs the full Cougar product range — UPS systems, industrial power supplies, PLC controllers, HMI touch panels, servo drives, and PFC modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Vadodara, and all other major cities. All repairs are performed at our ISO-certified facility in Vadodara, Gujarat with 72-hour turnaround on most faults.
What is the typical repair cost for a failed Cougar UPS battery charging module?+
Cougar UPS charging circuit repair typically costs INR 8,000 to 18,000 depending on whether the issue is isolated to the control IC (INR 8,000-12,000) or involves MOSFET bridge replacement (INR 12,000-18,000). Synchronics provides free diagnostic testing, written repair quotation, and parts warranty for 24 months. Emergency same-day repairs available for textile mills and pharmaceutical facilities on advance booking.
Can Synchronics repair Cougar PLC controllers with corrupted program memory?+
Yes, absolutely. Synchronics has specialized JTAG flash reading equipment to recover corrupted Cougar CPC and CPM series program memory. We can extract the firmware, verify checksums, identify corruption patterns, and reflash with corrected code. If original program source is lost, we document the recovered logic and provide commented assembly code. Typical recovery time is 2-3 business days.
Why do Cougar power supplies fail so frequently in Indian industrial environments?+
Cougar IPS and UPS equipment in India experiences higher failure rates due to four factors: (1) unstable grid voltage with transient spikes from switchyard operations, (2) high ambient temperatures (40-50 degC) in machinery rooms causing accelerated component aging, (3) harmonic-rich loads from VFDs and non-linear power supplies causing input rectifier stress, and (4) poor earthing practices allowing electrostatic discharge into signal lines. Synchronics recommends installing input voltage stabilizers, upgrading to three-phase isolation transformers, and implementing proper cable shielding.
Does Synchronics offer preventive maintenance contracts for Cougar automation systems?+
Yes. Synchronics offers quarterly and bi-annual preventive maintenance packages for Cougar PLC, HMI, and power supply systems. Services include thermal imaging of power components, capacitor ripple current verification, firmware update installation, I/O relay contact resistance measurement, and real-time clock battery replacement. Contracts start at INR 15,000 per year for single-device monitoring and scale for multi-machine textile mills and processing plants. Contact our sales team for customized quotes.
How do I send my COUGAR 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 COUGAR 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 COUGAR 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 COUGAR 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.
