Servo Voltage Regulator Controller RG7202N
RG7202N is a 72x72 mm controller for servo voltage regulators. It shows input and output voltage together, drives the motor to hold the output, runs automatically from 40 to 99 Hz, and logs min/max voltage and shutdown counts.

What it fits
Input and output on one glance
Operators see both voltages without paging the menu, which is the usual check on a running regulator.
Wider frequency window
40–99 Hz automatic operation covers generator-backed plants where line frequency moves.
Trip history on the unit
Min/max voltage and shutdown counts stay in memory so the plant can see what took the output down.
Installation
Insert the unit in the regulator and follow the connection schema for your model. Wiring docs and the PDF manual are on the documents page.
