JIREH Equipment We Repair — By Category
JIREH Product Lines We Repair
Our engineers are trained on the full JIREH product range. Below are the major product families we service.
JIREH UPS Systems (Online Double Conversion)
Three-phase online UPS systems delivering 10 kVA to 400 kVA capacity with advanced battery management. Common faults include inverter module failures, AVR voltage regulation drift, and battery charger circuit degradation under high ambient temperatures typical in Indian industrial environments.
JIREH Power Distribution Modules (PDM)
Modular power distribution and conditioning units with surge suppression and harmonic filtering. Repair focus includes IGBT gate driver failures, capacitor bank degradation, and control signal transmission loss across daisy-chained modules in multi-unit installations.
JIREH Battery Management Systems (BMS)
Intelligent battery supervision units for JIREH UPS systems with real-time cell voltage monitoring and temperature sensing. Typical failures: sensor malfunction, CAN communication errors, and relay contact wear causing false battery low-voltage alarms.
JIREH Static Transfer Switches (STS)
Automatic switchover devices enabling seamless transition between UPS output and utility mains. Faults commonly encountered: thyristor triggering delays, zero-crossing detection circuit noise sensitivity, and control card processor lockup during power cycling.
JIREH Charger/Rectifier Modules
Dedicated battery charging circuits with input conditioning and isolated output. Repair includes thyristor failure diagnosis, transformer secondary winding insulation breakdown, and voltage regulation feedback loop calibration.
JIREH Control & Monitoring Cards
SNMP-enabled network interface and local HMI control boards for UPS systems. Common issues: Ethernet port firmware corruption, display panel dead pixels, and sensor input conditioning amplifier drift affecting real-time load monitoring accuracy.

Common JIREH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in JIREH equipment arriving at our workshop.
- ✓JIREH UPS inverter module output collapse — Thermal cycling and moisture ingress in IGBT gate drive circuits cause solder joint cracking on the inverter PCB stack. This is especially prevalent in high-humidity Indian manufacturing zones where ambient temperatures exceed 45°C regularly.
- ✓JIREH BMS cell voltage sensor reading discrepancy — Individual battery cell voltage monitoring sensors develop drift (typically 0.1-0.3V error) due to isolation resistor tolerance degradation and capacitive coupling to high-dV/dt switching harmonics in the UPS inverter stage.
- ✓JIREH STS static transfer switch transfer delay exceeds spec — Zero-crossing detection circuits become desensitized due to coupling capacitor leakage current and thyristor gate triggering jitter from EMI coupling off the adjacent inverter. This causes delayed switchover during mains failure events—critical in data centre applications.
- ✓JIREH control card Ethernet SNMP communication timeout — Firmware corruption in the network processor or repeated TCP/IP stack crashes caused by under-voltage transients during generator switchover cycles. This isolates the UPS from remote monitoring systems and building management software integration.
- ✓JIREH charger/rectifier output voltage regulation drift — Feedback amplifier op-amp frequency compensation network loses phase margin due to electrolytic capacitor aging and ESR increase—typical in 35+ degree Indian industrial environments where UPS modules sit in hot equipment rooms with marginal cooling.
- ✓JIREH PDM power module IGBT thermal cycling fatigue — Repeated power cycling and harmonic-rich loads in textile mills and foundries cause junction temperature swings in output IGBTs. Solder joints in the power tab attach fatigue-crack, raising thermal resistance and causing thermal runaway during peak demand periods.
