CUSTOM POWER Product Lines We Repair
Our engineers are trained on the full CUSTOM POWER product range. Below are the major product families we service.
Custom Power UPS Systems
Single-phase and three-phase uninterruptible power supplies protecting critical automation equipment. Common faults include battery charging circuit failures, inverter module degradation, static bypass switch malfunctions, and microprocessor communication errors.
Custom Power DC Rectifiers
High-efficiency three-phase AC-to-DC rectifier modules for industrial control systems, PLC power supplies, and servo drive auxiliaries. Failure modes include thyristor short circuits, gate drive failures, and transformer core saturation.
Custom Power PDU and Distribution
Power distribution units with metered outlets, surge protection, and load monitoring for equipment racks and automation cabinets. Typical repairs address relay failures, surge suppressor degradation, and digital display malfunctions.
Custom Power Battery Modules
Sealed lead-acid and lithium-ion battery packs for UPS and emergency backup systems. Common issues include cell internal resistance rise, battery pack BMS communication failures, and terminal corrosion affecting charge-discharge cycles.
Custom Power Monitoring Controllers
SNMP and relay-based monitoring modules for UPS and power system remote supervision. Repair typically involves firmware reflashing, Ethernet port replacement, relay contact cleaning, and sensor calibration.

Common CUSTOM POWER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CUSTOM POWER equipment arriving at our workshop.
- ✓UPS inverter module complete failure — no output AC — IGBT power transistor failure in inverter bridge causes DC bus short or open circuit. Typically results from voltage spikes during load transients, component aging, or gate drive signal loss. Custom Power modules are susceptible when input voltage fluctuations exceed design margins.
- ✓Battery charging circuit malfunctions — trickle charge absent — Custom Power rectifier charging circuits fail when sensing resistors drift, current-limit opamps saturate, or feedback compensation capacitors dry out. Three-phase rectifier diodes may partially conduct due to solder joint cracks or thermal cycling stress.
- ✓Static bypass switch stuck in inverted state — load switching failures — Custom Power static transfer switches rely on triac or SCR pairs. Failure occurs when gate drive optocouplers lose signal integrity, feedback sensing circuits malfunction, or power transfer logic hangs during momentary mains sags. Thermal stress from repeated switching accelerates component degradation.
- ✓Microprocessor communication error — display blank or fault code locked — Custom Power microcontroller interfaces via RS-232 or Ethernet to status displays and remote monitoring systems. EEPROM corruption, oscillator crystal failure, or watchdog timeout causes controller reset loops. Power supply decoupling capacitor failures on logic boards also trigger this fault.
- ✓Temperature sensor circuit malfunction — false overtemp shutdown — Custom Power equipment uses NTC thermistor or PT100 RTD sensors in heatsink and transformer locations. Sensor wiring breaks, pull-up resistor drift, or analog-to-digital converter offset shift causes false thermal readings. Thermal compensation circuits may also fail if trim potentiometers are misaligned.
- ✓Surge suppressor components degraded — MOV clamping voltage increased — Custom Power PDU and UPS input circuits use metal oxide varistors (MOV) for surge protection. Repeated exposure to mains transients (common in Indian industrial sites with poor grid quality) causes permanent resistance increase and energy absorption capacity loss. Component aging accelerates in high-temperature cabinet environments.

What is the typical repair time for a Custom Power UPS module?+
Standard Custom Power UPS repairs (inverter module, rectifier, or battery charging circuit faults) take 7-10 working days including component sourcing, repair, load testing, and quality verification. Critical fault repairs such as IGBT replacement or firmware restoration may extend to 12-14 days. Rush repair (5-7 days) is available for mission-critical equipment; contact Synchronics for urgent service availability.
Can Synchronics repair Custom Power equipment with obsolete components?+
Yes. For Custom Power UPS and rectifier modules where original components are obsolete, Synchronics sources compatible equivalents with matching electrical characteristics. We test substitute components under full load to verify performance equivalence.
