2000 50A -48V 364A-3 SR Series Rectifier
Issue 6 January 1997
Product Description 2 - 9
Test Jacks: Two sets of test jacks are provided. One set
measures the plant voltage at the remote regulation sense point.
The other set measures the voltage internal to the rectifier before
the dc output circuit breaker. When the breaker is open and the
rectifier is on but disconnected from the local bus, the rectifier
output voltage can be adjusted without affecting the plant
voltage.
Wide ac Input Frequency Range: The rectifier’s power factor
correction circuit and switchmode technology allow it to operate
over 47 to 63 Hz with no degradation in performance.
Lightning and Switching Surge Protection: The rectifiers are
capable of withstanding, without damage, repeated surges of the
following waveforms (as defined in the referenced tables in
IEEE C62.41 - 1991):
Operation Without Batteries: The Lineage

Note
A metal oxide varistor (MOV) type service entrance protector
is recommended. (See IEEE C62.41-1991 Figure B10.)
Service entrance protection should be coordinated with the
MOV rating of the MOV in the rectifier. All rectifiers 364A
series 1:1 and 364A series 2:2 and lower have 275 vrms
MOVs. All other 364A-type rectifiers (including 364A3) have
320 vrms MOVs. Additional information on Total Surge
Management is available in application note 94ESDEV044
(available from Power Systems Document Control Center.)
