Variacs

 

 

The Controller Switch  turns off automatic regulation on our systems that include one of our automatic controllers.

Inside the cabinet there is a Manual Raise/Lower Switch that can be used when the Controller Switch is OFF to manually raise or lower output voltage.

 

Typical brush life in most applications is several years even with heavy usage. Operation for many years with the original brushes is not unusual.

Periodic brush inspection is recommended depending on use and environment.  For most applications once per year is sufficient.  Applications where the brush is in constant movement,  operated with repeated periodic overloads and/or operated at high ambient temperatures may require more frequent inspections.
