2000 50A Ferroresonant Rectifier J85502B-1
Issue 6 May 1999
Product Description 2 - 7
•
The digital output meter is optional on the J85502B-1
rectifier. The meter displays (1) the rectifier output current
when the selector switch is in the AMPS position, (2) the
rectifier output voltage when the selector switch is in the
RECT V position, and (3) the plant battery voltage when
the selector switch is in the BATT V position. The default
display is rectifier output current. Table 2-A gives the
accuracy of this meter in the various positions. The
