5 REGULATOR NAMEPLATE
The example above shows the main characteristics to be followed before installation.
NOTE
1. The identification nameplate is attached to the bottom of the regulator frame.
¹ For an input voltage of 80Vac, the maximum output voltage obtained is 76Vdc.
For 150Vac of input voltage, the output voltage obtained is 144Vdc, that is, the maximum dc output voltage is equal to 0.95 x
the ac voltage input.
² Recommended the use of multi-turn potentiometer.
