V-Guard VSDI Digital Stabilizer.

The V-Guard VSDI Digital Stabilizers are specially designed to protect inverter refrigerators and deep freezers from voltage fluctuations, ensuring safe and efficient operation.

There are popular models like VSDI 50 and VSDI 100, each suitable for different refrigerator capacities.

VSDI 50: Suitable for inverter refrigerators up to 450 liters.

It operates within a wide input voltage range of 120 V to 280 V, features a digital display for real-time input/output voltage monitoring, and has an Intelligent Time Delay System (ITDS) to protect compressor during power outages.

It also includes high and low voltage cut-off protection and comes in a durable ABS cabinet. It has a 5-year warranty.

VSDI 100: Designed for inverter refrigerators up to 900 liters or deep freezers up to 4 Ampere load.

It supports the same 120 V to 280 V input range and shares features like digital display system, ITDS delay protection, microcontrolled fast voltage correction, and high/low voltage cut-off.

It also has an elegant ABS cabinet and a 5-year warranty.

Both stabilizers provide automatic and microcontroller-based voltage regulation, display operational status on a digital panel, and ensure safe restarting of compressors via ITDS.

They are praised for protecting sensitive refrigerator components from voltage surges, overload, and sudden voltage drops. The products are positioned as reliable solutions for homes and offices facing erratic electrical supply.

In summary, the V-Guard VSDI series offers robust digital stabilizers with advanced features tailored for inverter refrigerators of varying capacities, with models like VSDI 50 and VSDI 100 distinguished by their supported appliance size and operational load.
