Servo Stabilizer

Servo Stabilizer - Single Phase

A voltage stabilizer is an Electrical & electronic device that supplies a consistent output voltage irrespective of input supply (Depending on Input Range). It protects Electric / electronic appliances from under and over /under voltage supply.

What is the main function of the Servo Stabilizer?

A Servo voltage stabilizer functions (Through Servo Motor) to automatically maintain a constant level (+/-1% Variation) of the voltage for our electrical appliances

Product Description

Servo stabilizers are designed and manufactured with latest technology and stringent quality measures to safeguard all types of your electrical appliances from crucial voltage fluctuations. It does never be a pay, when it comes, your valuable equipment shocks you with a breakdown pay.

Each Electrical/Electronic/Electromechanical equipments have a designed for a particular Working voltage. A highly fluctuation in AC supply is a common phenomenon in whole country. Fluctuation range is varying one place to another place depending on load ON/OFF. (In India designed single phase equipment 220V/230V/240V, 3 Phase Equipment 380V/400V/415V with 50HZ, But US/Japan Single Phase 110V/110V/120V, 3 Phase 200V/220V with 60HZ).

Constant voltage is very important for the better Efficiency, safety and long life of equipment and appliances, Some Equipments can withstand plus or Minus 20% or10% or 5% or 2% Of rated Voltage.It is Depended on purely Equipment Manufacture

  • What is unbalanced model servo stabilizer?

    The voltage sensing, correction With Each Phase Separate Motor control is done in each phase independently with respect to the neutral is also called as unbalanced type voltage stabilizers. Each Phase is different input voltage (Ex R-200V,Y-210V,B-220V But All Output 230V±1%) / LT Supply this type is suitable. Protections also sense each phase separately, single phase & Three phase both type of load suitable

  • What is balanced model servo stabilizer?

    The voltage sensing any 2 Phase & correction All Phases with common Servo Motor control is called as balanced type voltage stabilizers. All Phases Equal input voltage (Ex RY-330,YB-330V,BR-330V),HT /and OLTC with 3 Phase Load is suitable. Protections also sense each phase separately. Single phase load is not suitable for this type of stabilizer.

  • What is Servo Voltage Stabilizer /Servo Controlled Voltage stabilizer?

    Servo Stabilizer Consist of Servo Motor, Variac with Carbon Brush, Buck Boost Transformer, Servo Control PCB, Contactor / relay. In servo Stabilizer the servo motors involved with help of PCB, Auto Transformer and Buck Boost Transformer there is a small delay in voltage correction. However, output voltage accuracy is usually ±1% with input voltage variation of up to10% to ±50%,ABLE is the one of top most Servo stabilizer manufacturer in India with a tolerance of +/- 1% with high/low output voltage cut-off and overload cut-off. This ensures smooth operation and longer life for the equipments.

  • Where/why we use oil cooled servo stabilizer / Advantage of oil cooled stabilizer?

    Servo Stabilizer is mainmoving parts is dimmer, Dust Area the use are appear in Variac,So Variac is not move smoothly due to dust (there is possible of getting fire through sparking in dust area use Air Cooled),In dust area and Higher capacities oil cooled servo stabilizer is suitable Ex. Textile Unit, Garment Division,Foundry Unit, wood industries and pattern shop.
