STATIC VOLTAGE STABILIZER 

_

Static Voltage Stabilizer is an IGBT based PWM type buckboost voltage stabilizer which has tight regulation and fast correction speed which is impossible to obtain using conventional methods such as servo voltage stabilizers, SCR / triac type stabilizer, relay type stabilizer etc. This is specially useful in places where we need very fast correction speed, constant output voltage, overload current limiting and short circuit protection, soft start, high voltage cut-off and low voltage cut-off, automatic bypass, no wear and tear, long life and maintenance free which is impossible with other conventional relay type or servo control stabilizers. Since the circuit is fully solid state (no mechanical or moving parts) there will not be any wear and tear like the brush tear in servo stabilizer or relay degrading in relay based stabilizer.

SPECIFICATIONS: 

HIGHLIGHTS
  • Instantaneous correction speed – over 20000V per second
  • Discrete IGBT up to 30KVA single phase and 90KVA three phase
  • Single PCB for control stage, IGBT driver section and power stage.
  • Single contactor for three phase system
  • Individual contactor for three phase system (optional)
  • Single LCD for three phases
  • All protections included – low voltage, high voltage, overload and short circuit
FEATURES
  • Direct AC-AC conversion without rectifying to DC improves the efficiency, reliability and reduces the components.
  • Rapid cycle by cycle correction of output. It can correct sudden fluctuation in the line voltage.
  • Output regulation of +/-1% which is impossible in conventional stabilizer.
  • No distortion in output waveform.
  • Automatic bypass incase of failure.
