| 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
“STEADYVOLT” Servo Controlled Voltage Stabilizers.
“STEADYVOLT” conforms to I.S. 9815 |
|
| |
 |
| |
 |
“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.

 The
following are built-in features of each and every “STEADYVOLT”
Servo Controlled Voltage Stabilizer.
- Fully solid, state control circuitry, using high stability
industrial grade Silicon Semi-conductors. Relays are totally
eliminated, reducing chances of failure in the field.
- 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.

The following additional features
can be provided against specific enquiries at an extra cost.
- Under voltage and over voltage cut off.
- Output cut off in case the output voltage goes beyond set
limits. In both the above cases, time delay can be provided
to avoid problems caused by erratic tripping.
- M. C. B. /M. C. C. B. protection on the input/output.
- Digital Voltmeters, Ammeters and Frequency meters.
- Alarm to indicate input high/low and output high/low.
- In case of 3 phase units, single phasing preventor to trip
the supply in case of phase failure.
- Surge & Spike Suppressors.
