14 l Automatic Voltage Regulator – AVR-A-OPT-07 / AVR-A-OPT-07E / AVR-A-OPT-07/T
NOTE
* A potentiometer may be connected for fine voltage adjustment (5 k Ω / 3 W) at terminals.
* The U/F and Stb trimpots were preseted and sealed, but if adjustments are required, They can be
performed according to the procedures described in this manual.
