VTF
Features
With the three-phase automatic voltage stabilizer, a stable output voltage is achieved with a variable input voltage (power company supply or other generator.
The goal is to power industrial equipment that requires a stable voltage input.
It is of the electromechanical type powered by servomotor.
It features digital current and input and output voltage indicators, visual and audible alarms and built-in BY-PASS.
In addition, it is provided of the following protections:
– Against over temperatures.
– Against short circuits.
– Against over currents and overloads.
– Phase failure and loss of protection per phase.
– MCB input.
– Outside stabilization margins.
Applications
- Valid for installations where line tension experiences fluctuations throughout the day.
- Not valid for sudden changes in tension such as company maneuvers.
