2000 200A Ferroresonant Rectifier J85503B-2
2 - 6 Product Description
Issue 8 January 1999
Output Noise
The output noise is limited to 32 dBrnc. When measured with a
Psophometric noise meter, the noise is less than two millivolts
rms. (All of the above requirements are at full load, on battery,
and the noise is measured at the battery).
Rectifier Failure
Alarm (RFA) Test
A momentary closure either on the Control Board (208F1) or the
Interface Board (330C) board simulates a rectifier fail, generates
the RFA alarm, but does not shut the rectifier down.
Electromagnetic
Compatibility
(EMC)
In regard to radiated and conducted emissions, the J85503B-2
200-ampere rectifier complies with the United States of America
Federal Communications Commission (FCC) as required for
Class A applications. In addition, the rectifier meets all
specified operating characteristics when subjected to electric
fields up to 10 volts per meter over a frequency range of 20 to
1000 MHz.
Alarms
The J85503B-2, 200 ampere, 60-hertz rectifier can discern the
following alarms as well as provide diagnostic information for
certain alarms if you use a Galaxy or an MCS controller. When
any other controller is used, most of these alarms are available
from the interface board of the rectifier.
Load Share Fail
(LSF)
In -48 volt plants, the load share circuitry is fused in each
rectifier to prevent a failure in one rectifier from cascading into
other rectifiers. If this fuse operates, the load share failure LED
lights, and the LSF alarm issues. The rectifier continues to
provide power with its load share feature automatically disabled.
This alarm is not available in ±24 volt plants.
Fuse Alarms
(FA)
The low-power control circuits, regulation leads, and dc
capacitors are fused and alarmed. When any fuse alarm circuit
operates, except for the LSF fuse, the rectifier shuts down and
the fuse alarm (FA) and rectifier fail alarm (RFA) LEDs light.
Tripping the output circuit breaker also generates an FA.
Rectifier Failure
Alarm (RFA)
When a rectifier fails, an RFA issues to the controller and the
interface board and lights the front panel RFA LED. The rectifier
transmits a signal to a Lucent controller, if present, indicating
which one of the following has occurred:
