Features
- The efficiency of our industrial voltage controllers is more than 98%.
- The service life of our AVR is more than other conventional AVR.
- Our heavy-duty industrial stabilizers have 100% load continuous duty cycle.
- Our stabilizers are supplied with 5 years of unconditional guarantee.
- We decide payback period for our servo voltage stabilizers depending upon the input voltage variation and number of working hours of the plant.
- Our service engineers provide complete technical assistance for maintenance of the system.
- The automatic voltage controllers can handle up to 50 degree Celsius.
Effects of Voltage Fluctuation
The unbalanced power supply mainly hinders the efficient working of motors, which, in turn, results into the breakdown or deterioration of the machinery plant. The effect of unbalanced input voltage on three phase motor includes:
- With 5% unbalanced input voltage, the capacity of the motor reduces by 40% and electric consumption increases by 20 – 25%.
- Higher losses of motors also increase the losses of cables, switches, transformers etc.
- To avoid frequent tripping, the motor relays are kept higher than actual limits. Motors cannot withstand high current over a long period of time and burn out. This way, the current flows through the relays, contractors, cables etc., resulting into the failure of the equipment or fire.
In order to overcome this problem of unbalanced input voltage, it is recommended to get Servo Voltage Stabilizer installed with Individual phase Control.
Types of Automatic Voltage Controllers
Available for different technical specifications, the broad categories of our servo voltage controllers include:
- Unbalanced Type AVC
- Balanced Type Automatic Voltage Controller
- AVC with Bypass arrangement
- Automatic Voltage Controller with Isolation
