2000 400A, 60Hz Ferroresonant Rectifier J85503C-3
2 - 4 Product Description
Issue 10 July 2000
Output Fuse and
Fuse Alarm Switch
An output fuse protects the plant from excessive current due to rectifier
malfunction. The fuse is fast acting and may open without tripping the
output circuit breaker. The fuse alarm switch attached to the fuse sends
a Rectifier Fail Alarm and shuts down the rectifier when the fuse opens.
Output Current
Indication
A precision resistor shunt measures the rectifier output current. When
used with a Galaxy or Microprocessor Controlled System controller, the
rectifier provides an isolated 2- to 10-volt signal, corresponding to a
range of no-load to 125 percent of rated output load, to indicate the
rectifier drain on the controller. In addition, shunt access points are
available on the 329A board for measuring the shunt voltage directly.
Output Voltage
Adjustment Range
The rectifier is capable of providing up to 65 volts dc output at 50
percent of its rated output power and nominal input voltage.
Float/Equalize/
Boost
The rectifier can be put into the Equalize mode in one of three ways.
•
Receiving a signal from a Lucent Technologies Galaxy Controller
or an MCS Controller equipped with Version 4.0 firmware
•
Putting the front panel switch on the digital meter board in the
Equalize position
•
Receiving a closure on the EQL and EQLR terminals of the
interface board
Equalize
Acknowledge
In addition to the front panel Equalize LED, an Equalize acknowledge
signal (EQA, EQAR) is provided by the interface board. This signal
indicates that the rectifier is in the Equalize mode.
Remote Sense
Leads
These leads permit the rectifier to regulate the battery voltage by sensing
the voltage at the battery. Up to a 2-volt lead drop between the rectifier
and battery is permitted. The sense leads are also accessible from the
interface board.
Local Sense
The rectifier has an option, via user-selected DIP switch settings, to
regulate the voltage at the output terminals of the rectifier.
