We are one of the leading manufacturers of a quality range of Servo Controlled Voltage Stabilizer. These are provided with a drive motor of special construction having high torque, low speed output with instant start and stop reverse characteristics. The salient features and technical specifications are mentioned below:
Salient Features:
-
Widely fluctuating mains supply is always a cause of concern to the user of modern precision and sophisticated electrical and electronic equipment, like computers& NC / CNC machine tools
-
Even the performance of more rugged equipment like induction motors & heaters, deteriorates with fluctuating supply voltage
-
Servo-controlled voltage stabilizer is an effective & economic solution to this chronic problem
-
These are made in large varieties to meet every need of all types of industries
Specification:
Standard models voltage stabilizers are made to following specification.
| | 1 PHASE | 3 PHASE |
| INPUT | 180 V – 260 V | 300 V – 460 V |
| | | 360 V – 440 V |
| OUTPUT | 230 V – 240 V* | 380 / 400 V / 415 V* |
| FREQUENCY | 50 / 60 Hz |
| CAPACITY | 1 KVA TO 1000 KVA |
Built-in features:
-
A voltmeter with switch to indicate input / output voltages
-
Long term stability of ± 1%
-
Output setting - ± 5 Volts by a lockable potentiometer
-
High efficiency above 95%
-
Indications for "Power ON", "Input too low" & " Input too high"
Construction:
These have lower capacity units up to 50 KVA and are in air cooled single unit construction. Higher capacity units will be in two piece construction for the convenience of transportation & installation. Inter connecting cables / bus bars will be provided with the equipment. Both sections will be floor mounting type, and either one or both may be oil cooled depending on requirement.
Operation:
The voltage stabilizer works on a simple principal of adding or a subtracting a voltage to the supply voltage in appropriate quantity to correct it to the required level. This voltage to be added or subtracted is obtained from the mains itself, using a continuously variable voltage auto transformer, driven by a servo motor under the control of voltage sensing relay. This relay sense the output voltage continuously, compares with a highly stable reference and directs the drive motor to correct the output voltage to the set level.
