Features
Output Current “Walk-in”
This circuit controls the time (up to eight seconds) required for the rectifier to
reach normal operating conditions after it is turned on. This feature minimizes
the starting surge on the customer's power source.
Output Protection
Rectifier is equipped with an internal fuse for plant protection if a fault occurs
in a rectifier.
Electronic Current Limit
When the output current tends to increase above the current limit set point,
the current limit circuit overrides the voltage regulating signal and safely limits
the output current of the rectifier, thus preventing damage to itself or the
load.
High Voltage Shutdown (HVSD)
The rectifier senses the voltage at its output terminals. If this voltage is too
high, the rectifier will shut down to prevent the high voltage from damaging
itself or the load.
Restart
Upon shutdown, the rectifier will attempt to restart. The rectifier will also
accept a restart command from the controller for a remote restart. The
rectifier will attempt to restart three times before issuing a rectifier fail alarm
to the controller.
Fan Alarm and Control
The rectifier contains a cooling fan. The fan’s speed, which is based on
ambient temperature and output power level, is lowered during low-load and
low-temperature conditions to minimize audible noise and maximize fan life.
