V-Guard VG 400 for 1.5 Ton AC (170V to 270V) Voltage Stabilizer

V-Guard VG 400 Voltage Stabilizer protects split and window air conditioners up to 1.5 Ton from voltage fluctuations in the 170V-270V range. Advanced IC-based regulation delivers stable output to sensitive AC PCBs and compressor components, automatically disconnecting power when voltage goes below 170V or above 270V and resuming once the supply stabilises. The Intelligent Time Delay System (ITDS) introduces a 3-minute delay before restarting the AC after a trip – allowing compressor pressure to equalize and preventing mechanical damage from high-pressure restarts. Compatible with both inverter and fixed-speed ACs. Fire-retardant ABS cabinet, wall-mountable, backed by a 3-year on-site warranty from V-Guard.

Key Features

170V-270V wide working range: Corrects both brownouts and high-voltage surges – protects the AC through the full range of grid voltage instability common in Indian residential areas

Intelligent Time Delay System (ITDS) – 3 minutes: Allows compressor pressure to equalize after power cuts before restarting – prevents mechanical damage from high-pressure restarts

Automatic high/low voltage cut-off: Disconnects power instantly when voltage goes below 170V or above 270V, and resumes automatically when voltage returns to safe range

Advanced IC technology: Precise electronic voltage regulation – consistent, stable output for sensitive AC electronics and inverter PCBs

Fire-retardant ABS cabinet: Non-metallic, rust-free housing that does not corrode in humid bathroom-adjacent or outdoor-facing installation environments

Recommended Applications

Where the V-Guard VG 400 fits best

1.0 to 1.5 Ton inverter and fixed-speed split ACs: Primary use case – protects both inverter PCBs and conventional compressors from voltage fluctuation damage

1.5 Ton window ACs: Suitable for window AC units up to 1.5 Ton in residential and commercial installations

Areas with frequent brownouts: Locations where voltage regularly dips below 200V during peak load hours – the 170V lower limit handles most residential brownout conditions

Areas with high-voltage surges: Locations with unstable grid supply where voltage spikes above 240V – the 270V upper cut-off protects sensitive AC electronics
