Adjustment Controls of the VR3F Regulator
(1) Voltage droop potentiometer
(2) Voltage level potentiometer
(4) Fuse(s)
The VR3F regulator has voltage droop capability (1).
The VR3F regulator has the voltage level control (2).
However, the VR3F regulator does not have voltage
gain capability.
Voltage droop and voltage level are controlled by
multiturn potentiometers. The adjustment screws on
the potentiometers do not have a fixed stop. When
the potentiometer reaches the end of adjustment, a
ratchet action begins. The beginning of a ratchet
action can be felt with the adjusting tool. The
adjustment screw can be turned past the
potentiometer stop (ratchet action) without further
changing the potentiometer setting.
