Variac Controlled Rectifiers
Variac controlled galvanic rectifiers are one of the rectifier types
used in the metal plating industry. Named after the variac used to
control the input phase, these systems allow more precise adjustment
of the output voltage compared with stepped switch-controlled units.
Variac controlled rectifiers can be operated directly from the unit
in manual mode and can optionally be configured with a motorized
control system for remote operation. This allows rectifier control
to be transferred to the operator's working position.
In remote control systems, basic parameters such as voltage, current,
and operating time can be monitored and controlled. Depending on the
application requirements, the control equipment can be installed at
an operator station independent of the rectifier.
Variac controlled rectifiers manufactured by Aygün Electric can be
produced with air or oil cooling options depending
on the operating conditions of the plating process.

VARIAC CONTROL
Precise and User-Friendly Operation
Provides more precise voltage adjustment compared with stepped
switch systems, allowing operation suitable for different
plating processes.
01
Precise Voltage Adjustment
Thanks to variac control, the output voltage can be adjusted
more precisely according to process requirements.
02
Manual Operation
The system can be controlled directly from the rectifier
through the control equipment installed on the unit.
03
Remote Control Option
With a motorized control system, current and voltage settings
can be configured for remote control.
04
Remote Monitoring
Voltage, current, and time indicators can optionally be
transferred to an external operator station.
CONTROL STRUCTURE
Flexible Structure from Manual to Remote Control
Variac controlled rectifiers are fundamentally designed with
a simple and durable control structure. Manual control can be
preferred, or a motorized variac system can be used to make
the control point independent of the rectifier. This structure
provides ease of use, particularly in facilities where the
operator needs to work away from the equipment.
