User’s manual
Supply the electronic board
The REVO S thyristor unit, to work, requires a voltage supply for the electronic boards. The Max consumption is
10VA. The voltage supply for the electronic boards is configured in line with customer requirements that are
defined in the Order Code. The Order Code is written on the identification label.
Warning:
Before connecting or disconnecting the unit check that power and control cables
are isolated from voltage sources.

Voltage Supply for Electronic Boards (Auxiliary Voltage)
If it is necessary to change the value of the auxiliary supply voltage, move the jumpers as shown in the table
below.
The range of the auxiliary voltage that can be set depends on the transformer mounted on the board, see the
ordering code on Digit 8 (see table).

•
Attention! never link all the jumpers JP1+JP2+JP3 at the same time or JP3 + any other jumper, JP3 must
be always alone, follow only the configuration shown.
•
Attention! The auxiliary voltage is also used for firing synchronism, so it must be in phase with the
load voltage.
