Windsor 3 Phase AVS

A 3-Phase Automatic Voltage Switcher (AVS) is an electronic device designed to protect 3-phase electrical equipment from power supply issues like voltage fluctuations, phase imbalances, or phase failures. These devices are commonly used in industrial and commercial applications where equipment such as motors, compressors, or other heavy machinery relies on a stable 3-phase power supply.

Features of a 3-Phase AVS

1. Voltage Monitoring: Continuously monitors the input voltage of all three phases.
2. Automatic Protection: Disconnects the load if the voltage goes outside a safe operating range (over-voltage, under-voltage, or phase loss).
3. Phase Sequence Correction: Ensures the correct phase sequence (important for motors and sensitive equipment).
4. Time Delay: Offers a time delay feature before reconnecting to ensure stable power has returned.
5. Phase Imbalance Detection: Detects if one phase deviates significantly in voltage from the others and disconnects the load if necessary.
6. Built-in Surge Protection: Protects against transient voltage spikes.

Applications

• Industrial machinery: To ensure motors and compressors operate within safe voltage limits.
• HVAC systems: To protect air conditioning and refrigeration units.
• Power plants and substations: To safeguard sensitive control and communication equipment.
• Large commercial buildings: To maintain the stability of elevators, escalators, and other essential services.

Benefits

• Extends the life of electrical equipment by protecting it from electrical faults.
• Reduces downtime caused by voltage or phase-related issues.
• Ensures compliance with equipment warranties that often require voltage protection devices.
