Opto Instruments Pvt. Ltd. Manufactures Relay Type Automatic Voltage Stabilisers. Opto Instruments Pvt. Ltd. Offers power protection and controlling equipment. The Relay Type Automatic Voltage Stabilisers are designed to protect the expensive electronic and electrical equipment like - Televisions, Music Systems, Refrigerators, Air-conditioners, Water Coolers, Deep Freezers etc. When voltage drops too low, insufficient power compels motors to work harder at lower levels of efficiency, thereby affecting their life or burns them out in many cases. The Relay Type Automatic Voltage Stabilisers corrects the voltage before it reaches the equipment. The stabiliser steps up as soon as voltage drops and steps down to normal levels immediately when voltage rises. The Relay Type Automatic Voltage Stabilisers are offered in wide range of protections offered from as low as 50 Volts A.C. [single phase].
