The Basler Microprocessor-Based Reference Adjuster, Model RA-70. replaces Motor Operated

Potentiometers and provides a totally solid-state method of adjusting the setpoint on Basler Automatic

Voltage Regulators (AVRs), Basler Shunt Static Exciter-Regulators (SSEs), Basler Manual Voltage

Controls (MVCs), the Basler Var/Power Factor Controller (SCP-250) and other input devices having a

rheostat or potentiometer type control adjustment. The unit is designed for “behind-the-panel” mounting in

switchgear or control boxes. All controls, inputs, outputs, and LED indicators are located on the unit’s

front panel for ease of installation and adjustment. The RA-70 Reference Adjuster also comes equipped

with a 0-1 mA output signal to operate a position indicator that will indicate the setpoint position.

The Reference Adjuster is completely compatible with the following Basler equipment:

• Shunt Static Exciter-Regulator (SSE), both for automatic and manual adjust functions

• SSR series of Voltage Regulators

• SR-A, SR-E, SR-H, and SR-F series of Voltage Regulators

• APR series of Voltage Regulators

• AVC63-12 and AVC125-10 Voltage Regulators

• MVC-112. MVC-236. and MVC-301 Manual Voltage Controls
