Voltamp-STEADYVOLT

STEADYVOLT

The highly fluctuating A.C. Mains supply is a very common phenomenon in India and the difficulties caused by them are known too well and need not be enumerated. The emergence of the sophisticated computer era has created the need for a stable input supply as a basic necessity. The absence of stable supply creates problems in many equipments. Unsteady voltage supply conditions result in the total breakdown of sensitive and sophisticated equipments. The hope of getting a stable supply is very remote in our country and keeping this in view, VOLTAMP CONTROLS have developed microcontroller based STEADYVOLT Servo Controlled Voltage Stabilizers. STEADYVOLT conforms to I.S. 9815
Applications

STEADYVOLT Servo Controlled Voltage Stabilizers have many applications. To name a few For Computers, Xerox Machines etc.

For Micro processor based equipments like C.N.C. Lathes and a host of other C.N.C. based equipments/Machinery.

For Medical Equipments.

High capacity 3 Phase Stabilizers for entire factory and vital installations. STEADYVOLT increase life of tubelights & bulbs.

For Laboratories and process control equipments.
Features
The following are built-in features of STEADYVOLT Servo Controlled Voltage Stabilizer.
- Digital Voltmeter to read input & output voltage between P to N & phase to phase.
- Digital Ammeter to read output current.
- Input Digital Frequency meter for 3 Phase units only.
- Timer with 5 sec delay has been provided to avoid nuisance tripping.
- In case of 3 phase units, single phasing preventer is provided to trip the supply in case of phase failure or phase reversal (Contactor / MCCB/ACB provided at extra cost).
- Output cut off in case the output voltage goes beyond set limits. In both the above cases, time delay is provided to avoid problems caused by nuisance tripping.
- Fully solid, state control circuitry, using high stability industrial grade Silicon Semi-conductors.
- Efficiency better than 98% at full load.
- Nil wave form distortion.
- No effects of load power factor.
- Interchangeable plug in control card and module.
- Unaffected by change in supply frequency between 47 to 53 Hz.
- Large short time overload capacity, ideally suited for high starting current of inductive motors.
- No Phase shift.
- Easy manual operation in the unlikely event of auto circuit failure.
- High speed of correction up to 35V per second.
Additional Features

The following additional features can be provided against specific enquiries at an extra cost.
