2000 200A Ferroresonant Rectifier J85503B-2
2 - 2 Product Description Issue 8 January 1999
Controller: provides the local and remote control, monitor and
diagnostic functions required to administer the battery plant.
Batteries: provide energy storage for an uninterrupted power
feed to the using equipment during loss of ac input or rectifier
failure.
DC Distribution: provides overcurrent protection, connection
points for the using equipment, and bus bars used to interconnect
the rectifiers, batteries, plant shunt, and dc distribution.
Converters: transform -48 volt source voltages into regulated,
low-noise 24 volt dc power sources for use with
telecommunications loads.
Features
The J85503B-2 rectifier offers the following standard features.
Output Current
“Walk-in”
This circuit controls the time required for the rectifier to reach its
rated output voltage after it is turned on. Initially, the output
voltage is about 80 percent of normal, and gradually increases to
the required value in approximately 10 seconds. As the output
voltage “walks in,” so does output current. This feature
minimizes the starting surge on the customer’s power source and
is especially important with a more limited power source, such
as an engine driven alternator.
