2000 400A, 60Hz Ferroresonant Rectifier J85503C-3
2 - 2 Product Description
Issue 10 July 2000
•
All circuits for power control, alarms, voltage regulation, current
limiting, restart, plant interface, and remote monitoring/control are
mounted on replaceable circuit modules. Front access to the circuit
modules simplifies replacement or adjustment, if required.
Standardized modules simplify parts inventory, resulting in lower
costs and better equipment availability.
•
The rectifier can be used in a plant with or without batteries and
with or without a controller. The load share feature, equalize
feature, noise filtering, and interface board adapt the rectifier to
practically any application.
Features
The J85503C-3, 400 ampere 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.
Electronic Current
Limit
The rectifier provides a constant output voltage up to its rated output
current, at which point it provides constant current. This current limit set
point is adjustable from 30 to 110 percent of the rectifier rating, 120-440
amperes. When the output current tends to increase above the current
limit setting, the current limit circuit overrides the voltage regulating
signal and limits the output current of the rectifier.
Backup Current
Limit
In addition to the electronic current limit, the ferroresonant transformers
are naturally current limiting to 125-175 percent of full load, or 500-700
amperes.
Selective High
Voltage Shutdown
If the battery voltage goes too high, a Lineage

all of the connected rectifiers. This signal causes the rectifier(s)
delivering more than 10 percent of full load to shut down. The remaining
rectifiers continue to operate. The J85503C-3, 400 ampere also accepts
a selective high voltage shutdown (HVSD) signal from any external
source via the interface board.
