GIC & HIQUEL Single Phase Voltage Monitoring Relays – Under & Over Voltage Protection GIC & HIQUEL Single Phase Voltage Monitoring Relays
GIC and HIQUEL Single Phase Voltage Monitoring Relays safeguard electrical systems and sensitive equipment from overvoltage and undervoltage faults. These compact and precise relays continuously measure line voltage and trip when the supply moves outside defined limits, helping to prevent damage to motors, power supplies, and control electronics.
🔧 Technical Highlights:
- Function: Monitors AC line voltage and disconnects output during under or overvoltage conditions.
- Operating Range: Typically 160–280 V AC for 230 V single-phase systems (model dependent).
- Trip Thresholds: Independently adjustable upper and lower voltage limits.
- Trip Delay: Adjustable on/off delay to prevent nuisance tripping due to short fluctuations.
- Supply Voltage: Universal 24–240 V AC/DC or self-powered designs available.
- Outputs: SPCO or DPCO relay contacts for alarm or disconnection circuits.
- Indicators: LED display for power, trip, and relay status.
- Mounting: 35 mm DIN rail or panel mount enclosure for easy integration.
- Compliance: CE and RoHS; designed to IEC/EN 60255 protection standards.
✅ Benefits:
- Protects motors, PLCs, and control electronics from voltage instability.
- Prevents nuisance tripping with adjustable delay and threshold settings.
- Compact DIN rail design saves panel space.
- Clear visual indication simplifies fault diagnostics.
- Reliable, maintenance-free operation from trusted manufacturers GIC and HIQUEL.
🚀 Applications:
- Protection of single-phase motors, pumps, and compressors.
- Control panels and automation systems.
- HVAC, lighting, and building services equipment.
- UPS, inverter, and generator monitoring.
- Residential and industrial machinery voltage protection.
GIC and HIQUEL single phase voltage monitoring relays ensure dependable voltage protection across automation, process, and electrical systems — improving equipment reliability and operational safety.
FAQs
- Q: What does a voltage monitoring relay do?
A: It monitors the supply voltage and activates or deactivates its output relay when the measured voltage falls below or rises above the preset limits. - Q: Can I use these relays for both 50 Hz and 60 Hz systems?
A: Yes. GIC and HIQUEL single phase voltage monitoring relays are designed for both 50 Hz and 60 Hz supplies, making them suitable for international installations.
