2000 25A Ferroresonant Rectifier J85502A-1
Issue 4 May 1998
Product Description 2 - 7
•
The digital output meter is optional on the J85502A-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
accuracy of the reading depends on the vintage of the digital
meter board (CM3) in the rectifier. The POWER (control)
