2000 50A -48V 364A-3 SR Series Rectifier
3 - 8 Engineering and Ordering Issue 6 January 1997
RID Rectifier Identification is an opto-isolated closure between RID
and RTN2 (pin 1) indicating to the controller that the rectifier is
in a normal mode and is able to supply power to the load.
RS/RSR RS/RSR is an isolated contact closure between RS and RSR
originating in the controller which forces shutdown rectifiers to
attempt a restart following high voltage shutdowns.
RTN Return is used as the signal return for all non-isolated contact
closures between the basic controller board and the rectifier.
This lead is connected to the plant discharge return bus.
RTN2 Return 2 is used as the signal return for all opto-isolated contact
closures between the rectifier and the microprocessor board of
the ECS controller (CP2). The emitters of the opto-isolators are
connected to this lead in the rectifier. This lead is connected to
discharge return in the controller.
STCB Standby/Circuit Breaker off is an opto-isolated closure between
STCB and RTN2 (pin 1) indicating to the controller that the
rectifier is in the standby mode or that the output circuit breaker
is in the off position.
TA Thermal Alarm is an opto-isolated closure between TA and
RTN2 (pin 1) indicating to the controller that the rectifier has
shut down due to overtemperature.
TRH Transfer Handshake is a contact closure between TRH and
RTN2 (pin 1) confirming to the controller that the rectifier has
shut down in response to an OTR signal.
Rectifier Sizing This section discusses the factors to be considered in
determining the number of rectifiers required in both
Note
Use of a non-isolated contact or improper mixing of rectifiers
could result in improper operation of the rectifier high voltage
shutdown and restart circuits.
