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

Microtek Pearl Series AC Stabilizer is an energy-efficient automatic voltage stabilizer range designed to protect air conditioners from fluctuating mains conditions. Pearl EM models combine automatic voltage correction, Smart Time Delay, Intelli Auto Start, low and high voltage cut-off and overload protection for compatible 1.5 ton and 2 ton 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.
Pearl EM stabilizers combine automatic regulation, compressor-oriented delay logic and electrical protection for compatible AC loads.
Automatically steps voltage up or down according to incoming mains conditions and the selected model’s operating range.
Provides a controlled restart delay before supplying the AC following relevant power or voltage-recovery events.
The stabilizer resumes automatic operation when acceptable input voltage conditions return.
Disconnects the connected AC when incoming voltage moves beyond the specified limits of the selected Pearl EM model.
The Pearl Series incorporates protection intended to respond to excessive electrical loading conditions.
Microtek’s Save Power Technology supports energy-efficient stabilizer operation during frequent power and voltage fluctuations.
Microtek Pearl Series AC Stabilizer models combine automatic voltage control with protection functions intended specifically for compatible air conditioners.
Model selection depends on AC tonnage and the minimum and maximum mains-voltage conditions at the installation location.
Input voltage, current rating, compatible AC capacity, dimensions and display configuration vary by model. Confirm the selected Pearl EM model before applying model-specific values.
Key information about AC capacity, working voltage, Smart Time Delay and model selection.
Microtek Pearl Series AC Stabilizer is an automatic voltage stabilizer family designed specifically for compatible air conditioners up to 2 ton.
Microtek lists multiple 12A Pearl EM models for air conditioners up to 1.5 ton. The appropriate model depends mainly on the mains-voltage range at the installation location.
Pearl EM 5170+, 5150+, 5130+ and 5090 are catalogue-listed 15A models for compatible air conditioners up to 2 ton, with different working voltage ranges.
Smart Time Delay introduces a controlled waiting period before restoring output to the connected air conditioner following relevant power or voltage-recovery conditions.
