Three-Phase Fully Automatic Servo Voltage Stabilizers

Product Features

• Standard: Input: 275 V - 450 V (AC) (3 phases + neutral)
• Low-voltage type: Input: 205 V - 400 V (AC) (3 phases + neutral)
• Output: 380 V (AC) (3 phases + neutral)
• Safe use with all electrical devices.
• Working principle: microprocessor-controlled, fully automatic servo system
• Regulation speed: 90 V/second.
• Output regulation: the output voltage is sinusoidal. Accuracy: ±2 %.
• Display: digital displays for input and output voltage on each phase.
• Measurement technique: True RMS
• Efficiency: above 98 %.
• Separate by-pass switches are provided for each phase in case of a fault, so the stabilizer can be taken out of circuit and the system supplied directly from the mains.
• Available from 10.5 kVA to 2,000 kVA.
• Over/under-voltage and phase protection unit (optional):
• a) Cuts the stabilizer output for 8 s if the input voltage is too high or too low for the correction range, or if the mains is interrupted and returns at a high voltage. Output is restored once regulation is complete. No output is given in the event of a fault.
• b) Cuts the output completely if one of the three phases fails, and switches back on automatically when the phase returns. This prevents three-phase motors from running on two phases and burning out.
• Our stabilizers are CE certified.
