Product Description
This voltage protector (Model V27) safeguards appliances, particularly refrigerators and kettles, from unstable power supply by automatically disconnecting power during voltage fluctuations. Equipped with real-time digital monitoring (MCU controled), overload protection, and automatic shutdown, it ensures reliable protection against surges and sags.
Key Parameters
- Over Voltage Cut-off: 260V AC (customizable according requirment)
- Under Voltage Cut-off: 160V AC (customizable according requirment)
- Delay Time: 180 seconds
Protection Features
Overvoltage Protection
Issue: Sudden voltage spikes from grid failures or equipment operations can damage refrigerator compressors or control circuits.
Solution: Instantly cuts power when voltage exceeds the set limit (e.g., 260V), protecting critical components and extending appliance lifespan.
Undervoltage Protection
Issue: Low voltage due to peak demand or aging infrastructure strains the compressor, risking motor burnout.
Solution: Disconnects power when voltage drops below the lower threshold (e.g., 165V), restoring supply only after stabilization.
Transient Voltage Suppression
Issue: Lightning strikes or large equipment switching can generate destructive voltage surges.
Solution: Integrated surge protection components (e.g., varistors) absorb transient spikes, shielding internal circuits.
Delayed Restart Function
Issue: Immediate compressor restarts after shutdown may cause pressure imbalances and mechanical stress.
Solution: Enforces a 210-second delay before re-energizing, allowing system stabilization and reducing wear.
Electrical Fire Prevention
Issue: Voltage instability increases risks of overloads or short circuits.
Solution: Timely voltage cutoff minimizes fault conditions, enhancing household electrical safety.
Installation Guide
- Insert the 1426 Voltage Protector into a grounded AC outlet.
- Turn off and unplug the appliance to be protected.
- Connect the appliance to the protector’s outlet (labeled "V14").
- After the 210-second delay, the appliance will power on automatically under stable voltage conditions.
Voltage & Frequency Compatibility
100–127V, 60Hz: Suitable for North America (e.g., USA, Canada).
220–240V, 50Hz: Designed for regions like South Africa, Europe, and Asia (e.g., China).
Usage Notes
Travel Adapters: Required for international compatibility with local socket types.
Voltage Converters: Necessary if appliance voltage ratings differ from the local supply.
Summary
The V27 Voltage Protector continuously monitors voltage fluctuations via its real-time display, ensuring round-the-clock protection for refrigerators and other sensitive appliances. Its customizable thresholds, surge suppression, and intelligent delay mechanisms provide a robust defense against electrical hazards.
