1KVA Servo Voltage Stabilizer - ESV-1P01

ESV servo stabilizer is an Alternative Current (AC) voltage regulation and protection device which provides safe and stable voltage for businesses and home users who have constant low or high voltage problems. It adjusts the low or high network voltage to the desired voltage value and keeps it constant. It works slowly because it has an electromechanical structure. It is produced with traditional technology and offers the most economical solution for voltage correction.

What is ESV Servo Voltage Stabilizer?

ESV servo stabilizer is an Alternative Current (AC) voltage regulation and protection device which provides safe and stable voltage for businesses and home users who have constant low or high voltage problems.
It adjusts the low or high network voltage to the desired voltage value and keeps it constant. It works slowly because it has an electromechanical structure. It is produced with traditional technology and offers the most economical solution for voltage correction.

How Does It Work?





ESV Servo stabilizer works on the principle of applying a variable voltage to the secondary of the Booster transformer connected in series between the network and the load. In order to adjust the variable voltage, a brush made of graphite is moved by the motor on the copper windings of the Variac unit. Microprocessor based control card decides how much the brush will be moved.

The measuring time of voltage drops and spikes approx < 40 milliseconds
Voltage Correction time < 1-5 seconds

Simple and economical solution in traditional structure

The Variac-Motor system used in the ESV Servo Stabilizer has a simple structure. The electronic card controlling the motor is also small and economical. It is suitable for use in small commercial applications and homes where the network voltage does not change much.

It is the most economical voltage stabilizer solution. It requires periodic maintenance at least 1-2 times in a year. It is not suitable for use in dusty, humid, vibrating environments. It is specially produced for special projects.

Input Voltage Range

The input voltage range of the ESV Servo Stabilizer is determined at the order stage and cannot be changed later. There are 3 different models as standard. The below diagram shows the voltage regulation performance of each model.




Output voltage tolerance of ESV Servo Voltage Stabilizer are +/- 2%
Standard type 3 phase ESV Servo voltage stabilizers can operate in 3 phase + Neutral (4 wire) installations. Neutral connection is required for safe operation.

Maintenance By-pass Switch

A Maintenance By-Pass switch can be added to the ESV servo stabilizer, which ensures that the loads are transferred to the grid in case of maintenance or failure. Maintenance By-Pass switch is an I-0-II position changeover switch and is manually controlled. During the Maintenance By-Pass operation, the power to the loads is cut for a short time.

Applications

The ESV Servo stabilizer is the best solution for all commercial businesses, institutions and home users affected by voltage fluctuations, such as small factories, small commercial businesses, home applications, office blocks, shopping malls,stores, restaurants and chain stores.
