*Digital system with 16 stages (where it can jump to the required
stage without passing the other stages) .
*Working as a voltage fixer ± 4% volt and equipped with a
compensation circuit to continue connection between stages.
*Protection from high voltage which resulted from the network or
the regulator at 245 voltages.
*Protection from shortage and from current increase by a magnetic
*Transformer for transferring to the network voltages, and to
cancel regulation when necessary.
*Delay working at the operating beginning for ten seconds in order
to stabilize with network, it possible to control the time for 3
*Delay in organizing operation to avoid network fluctuations,this
delay will be canceled at 200 voltages.
*Simultaneous: Since exchange of regulating pads is synchronously with zero
voltage wave in order to avoid sparks on contacts.
