2000 100A Ferroresonant Rectifier J85503A-1
2 - 4 Product Description
Issue 6 October 1998
•
Fuse alarm circuit: The low-power control functions shut
down the rectifier if a fuse alarm (FA) occurs. One fuse
alarm protects each of the regulation leads. When any fuse
alarm occurs, a Rectifier Failure Alarm (RFA) LED lights
on the front panel and an RFA signal is generated.
•
Unbalance alarm: An alarm occurs and the rectifier shuts
down if severe unbalance develops between the
ferroresonant transformers. The rectifier-fail circuit delivers
this alarm after a 3-second delay to allow transient
disturbances to subside, such as those occurring during
initial turn-on.
•
Man alarm: This alarm indicates that either the rectifier
has been turned off manually or has lost commercial input
power.
•
Restart circuit: The rectifier has an automatic restart
feature that is compatible with most controllers. If a rectifier
shuts down due to the external selective high voltage
shutdown, most controllers try at least once to restart it
automatically.
•
Remote sense leads: These leads permit remote regulation
of the rectifier.
•
TR: This signal (Transfer Rectifier) remotely shuts down
the rectifier.
Additional
Features
Dynamic Response
For any step load change of 10 to 90 percent, or 90 to 10 percent,
or a step change of 10 percent of the input voltage, the sense
point voltage remains within 5 percent of its setting, and returns
and remains in the 1/2 percent band within 300 milliseconds. For
batteryless operation, for any step load change of 50 to 90
percent, or 90 to 50 percent, or a step change of 10 percent of the
input voltage, the sense point voltage remains within 10 percent
of its setting, and returns and remains in the 2 percent band
within 500 milliseconds.
Electromagnetic Compatibility (EMC)
The J85503A-1 rectifier complies with FCC Docket 20780, Part
15, Subpart J, as required for Class A applications. In addition,
