to and stored in the converters that is used by each converter for
independent high voltage monitoring. The threshold can be set from -
50.0V to -60.0V or +25.0 to +30.0V with a factory setting of -58.0V
and +29.0V for 48V and 24V outputs, respectively.
Low Voltage
Disconnect Enable or Disable for a feature that allows attached converters to be
placed into Standby once an input voltage threshold is reached. The
factory default for this feature is Disabled.
Disconnect Converter input voltage threshold to be used to place all converters
into Standby. The converter disconnect threshold is adjustable from -
40.0V to -50.0V and +20.0V to +25.0V with a factory default of -
46.0V and +23.0V for 24V and 48V output converters, respectively.
Reconnect Converter input voltage threshold to be used to return all converters
from Standby to On. The converter reconnect threshold is adjustable
from -44.0V to -54.0V and +22.0V to +27.0V with a factory default of
-52.0V and +26.0V for 24V and 48V output converters, respectively.
Voltage Alarms Has the ability to set similar secondary DC bus level alarms as found
with the rectifiers and the primary DC bus. This includes Very High
Major, High Minor, and Very Low voltage.
Very High Major
The High Voltage Shutdown Alarm (HVSD) threshold for the
secondary DC bus. When reached, the controller will send out the HV
shutdown command to the serial converters so that the offending
converter will shut itself down. The threshold can be set from -50.0V
to -60.0V or +25.0 to +30.0V with a factory default setting of -56.00
and +28.5V for 48V and 24V converter outputs, respectively.
High Major
This alarm indicates an abnormally high output voltage on the
secondary DC bus. The controller does not attempt to shut the
offending unit down. The threshold can be set from -48.0V to -60.0V
or +24.0 to +30.0V with a factory default setting of -54.00 and +27.0V
for 48V and 24V for converter outputs, respectively.
Very Low
Secondary DC bus alarm threshold used to indicate something
dragging the bus to an undesired voltage level or an incorrect setting.
The threshold can be set from -40.0V to -54.0V or +20.0 to +27.0V
with a factory default setting of -46.0V and +23.0V for 48V and 24V
for converter outputs, respectively.
Power-Part Numbers
This section provides access to add a secondary identification of company number for a specific
component of the power system. The number is shown under inventory. Following is a sample
