Three Phase Oil Cooled Voltage Stabilizer : 100 Kva Brand HIREL Display Type Lcd Phase Three Phase Insulation Class B Power Rating 100

This is 100 KVA Oil Cooled Servo Voltage Stabilizer for mains voltage (AC input and AC output). This is a new switching topology where PWM is done directly in AC-to-AC switching, without any harmonic distortion. In this topology there is no need to convert the AC input to DC and again convert it back to regulated AC output. This simplifies the design, reduces the component count and improves the efficiency and reliability. The power stage is an IGBT chopper control. The chopping frequency is around 20KHz which ensure absolutely silent operation and pure sine wave output (no waveform distortion).

The control section is based on dsPIC controller which ensure quick correction of output which is not possible in conventional relay type stabilizer or servo controlled stabilizers. The circuit is having LCD display which will show all parameters like: input voltage, output voltage, connected load, your company name (We will program your company name in the dsPIC at the time of technology transfer) etc.

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.

Features:

1. Direct AC-AC conversion improves the efficiency, reliability and reduces the components.

2. Rapid cycle by cycle correction of output. Can correct sudden fluctuation in the line voltage. For example using a welding machine in the same line will cause sudden fluctuation in the line voltage which can not be corrected with conventional relay type and servo controlled voltage stabilizers, where Static Voltage Stabilizer can correct it.
3. Output regulation of /- 1% which is impossible in conventional stabilizer.
4. No distortion in output waveform.
5. Overload cutoff
6. Over voltage and under voltage cutoff.
7. LCD display for displaying all parameters and your company name.
