Figures 1 and 2 show the front and rear views of the fully equipped rectifier.

Figure 1 - NT5C06B/C Rectifier (front view)

Local float / equalize control

The rectifier is equipped with a momentary Float/Equalize switch. When the

switch is held in the EQL position, the rectifier changes to equalize mode

and boosts the output voltage to the value set by the EQL potentiometer.

Otherwise, the rectifier delivers a float voltage set by the FLT potentiometer.
