Types of Stabilizers

There are three main types of voltage stabilizers:

1. Electromechanical Stabilizer

These use a motorized variac and relay to maintain stable voltage. They have a slow response time but are inexpensive.

2. Servo Motor Stabilizers

Faster than electromechanical stabilizers, these use servo motors to adjust output voltage. They are more compact but expensive.

3. Digital Stabilizers

Most advanced type, these use microcontrollers and digital displays for voltage correction. They are fast, accurate but costlier.

Stabilizer Usage and Maintenance Tips

Here are some usage and maintenance tips for stabilizers:

• Install the stabilizer close to the AC on a wall mount or stand. Keep away from direct sunlight and rain.
• Do not cover or box in the stabilizer. Allow minimum 1 foot space around it for air circulation.
• Connect the stabilizer directly to the wall outlet. Do not use extension cords or overload the circuit with other appliances.
• Check that the stabilizer rating matches your AC tonnage to avoid overloading.
• Monitor the LED indicators to ensure input and output voltages are within range.
• Clean the stabilizer periodically by wiping with a dry cloth. Do not wet or spray water on the unit.
• Ensure proper earthing connection to the stabilizer to avoid electric shocks.
• Get the stabilizer serviced annually by an authorized technician for long life.
