Microtek Pearl Series AC Stabilizer Overview

Automatic Voltage Protection for Air Conditioners

Microtek Pearl Series AC Stabilizer products are designed to protect compatible air conditioners from low voltage, high voltage and frequent fluctuations in the incoming mains supply.

The Pearl EM range includes 12A models for air conditioners up to 1.5 ton and 15A models for air conditioners up to 2 ton. Multiple input-voltage ranges allow selection according to local electrical conditions.

Wide-input variants are available for locations with significant voltage variation. Depending on model, published working ranges extend from 170V–270V to as wide as 90V–300V.

Intelli Auto Start enables the stabilizer to operate automatically without routine manual intervention. The system steps voltage up or down according to the incoming supply and selected model characteristics.

Smart Time Delay provides a controlled delay before the connected air conditioner is energised following certain supply interruptions or voltage-recovery conditions. This feature is particularly relevant for compressor-based cooling equipment.

Low and high voltage cut-off disconnects the grid supply when the input moves beyond the permitted limits of the selected stabilizer, helping isolate the connected AC from unsuitable voltage conditions.

Pearl Series models also incorporate overload protection and Microtek Save Power Technology. Selected products include additional Intelli Microchip control, Silver Caked Relay and Intelli Thermal Management technologies.

Microtek Pearl Series AC Stabilizer Features

Intelligent Voltage Management for Air Conditioners

Pearl EM stabilizers combine automatic regulation, compressor-oriented delay logic and electrical protection for compatible AC loads.

Automatic Voltage Regulation

Automatically steps voltage up or down according to incoming mains conditions and the selected model’s operating range.

Smart Time Delay

Provides a controlled restart delay before supplying the AC following relevant power or voltage-recovery events.

Intelli Auto Start

The stabilizer resumes automatic operation when acceptable input voltage conditions return.

Low & High Voltage Cut-Off

Disconnects the connected AC when incoming voltage moves beyond the specified limits of the selected Pearl EM model.

Overload Protection

The Pearl Series incorporates protection intended to respond to excessive electrical loading conditions.

Save Power Technology

Microtek’s Save Power Technology supports energy-efficient stabilizer operation during frequent power and voltage fluctuations.
