Connection D
(
See page 12
if the generator will be paralleled using this connection)
Connection D
is a Half-Wave rectified configuration, which allows a maximum of
52VDC at 50 ADC continuous with an input voltage of 120VAC.
This connection is typically used on very low voltage excitation fields (generally referred
to as 32V fields) and on brushless generator fields where the full-load excitation voltage
is 32VDC or less, but the exciter field current is between 25 and 50ADC.
Note that the maximum input voltage to the SE350 Static Exciter Module in this
configuration is 139VAC!
DO NOT input 208/240VAC into the SE350 in this configuration!
Severe regulation problems and possible damage to the regulator or exciter field can result! For
use on 480V systems, use a 480-120V step-down transformer.
Make sure Terminal AC2 is connected to the Generator Neutral.
Failure to verify this
wiring before energizing the generator can result in severe damage or a voltage runaway
condition!
NOTE:
It is not necessary
to jumper terminals
7 and 8 if not using
the Remote Voltage
Adjustment!
NOTE:
If the generator is to be
operated below 50/60 Hz, a
disconnect or switch should
be installed in series with
red wire of the SE350.
NEVER install a switch or
breaker on the DC or
Exciter side of the Static
Exciter!
Only install a
switch or disconnect in
the red wire, or on the AC
side of the SE350!
