7.2.1 Output Voltage Modes
Voltage modes can be thought of as modes that, under software control, can directly adjust the output voltage.
The qualification of ‘under software control’ is made because there are processes that occur in the rectifier that
can change the output voltage that do not adjust the output voltage directly (such as the rectifier being in current
limit).
The following table lists four Output Voltage Modes and a description of when they are active:
Output Voltage Modes Active when…
Float Output voltage is set to the float voltage setting.
Equalize Output voltage is set to the equalize voltage setting.
Battery Test Output voltage is set to the battery test voltage setting.
Safe Output voltage is set to the safe mode voltage setting.
Table D–Output voltage modes
7.2.2 Output Current/Power Modes
These modes directly affect the output current and power.
The following table lists the four Output Current/Power Modes and a description of when they are active:
Output Current/Power Mode Active when…
Temperature foldback mode Output current and power limit have been reduced due to high temperature of the
heatsink or internal ambient temperature sensor.
AC foldback mode Output current and power limit have been reduced due to low AC input voltage. Note:
this will reduce the risk of tripping an AC breaker due to increased AC current draw as
the AC voltage decreases.
Short circuit foldback mode Output current limit has been reduced due to a short circuit at the output.
Internal fault foldback mode Output current limit has been reduced due to an internal fault.
