Precision engineered
Automatic Voltage Stabilizers use an advance electronic servo-motor concept to control a motorized variable transformer. Due to motorization, there is a small delay in voltage correction. But output voltage accuracy is usually 1% with input voltage changes up to 50%. These machines do not get disturbed by unduly power factor or frequency variation. This kind of modern technology is extremely effective when considering large three phase applications, as it is able to maintain its accuracy of all three phases, both line to line and line to neutral, irrespective of input voltage balance and load balance at any power factor.
These modern stabilizers when encounter Erratic / Normal AC Mains Supply as input; regulates this input to provide a stable Output Supply of 220/230 V ±???7 %. normally experienced with inductive loads. We offer automatic voltage stabilizer from 1 KVA to 1000 KVA.
Salient features: - Elegant & Sturdy in construction
- Microcontroller design
- No effect on system power factor
- Accepts wide variations at input AC. (up to 90 V AC)
- High efficiency-typically 95 %
- Higher over load capabilities for high starting & regenerative currents repeated frequently in CNC machines
- High reliability, Ease of maintenance and Energy Saving
This kind of servo stabilizer contains an AC synchronous motor, which is coupled with an auto transformer using gears. Depending on the input fluctuation, the servo motors adjusts the output. We use embedded software in RISC micro controller for the control circuitry. It is used in areas where input supply and load output are single phase/ 3 phase operated.
Application areas: - 3 Phase Motor Applications
- CNC Machines
- Colored Offset Printing Press
- Escalators and Elevators
Three Phase Input & Three Phase Output (Unbalanced Load): This kind of servo stabilizer consists of three independent AC synchronous motors coupled with three Auto Transformer using a shaft and compatible gears. Depending on the input fluctuation, the servo motors adjusts the output of the Auto-transformer to provide a stabilized output. We use embedded software in RISC micro controller for the control circuitry of each phase. It is used in areas, where input supply is three phase and load is unbalanced in all the phases.
Application areas: - Medical Equipments
- Industrial Loads
- Lighting Load Applications
- Air Conditioning Units
