Thermal Alarm
The rectifier senses the internal operating temperature and will issue a
thermal alarm if the internal temperature exceeds a safe operating level.
Ambient temperatures above the maximum rating will result in a rectifier
shutdown and the issuing of a thermal alarm (TA).
Autonomous Operation
Rectifiers will continue to power the load if the controller fails or if
communication is lost.
Controller Communications Alarm
When communications between the rectifier and controller are interrupted,
the rectifier continues to operate and the red Fail LED on the rectifier blinks.
Connectorized
The rectifiers provide the controller with a full complement of status and
alarm signals. The rectifier status and alarm signals, ac input, and dc output
are all connectorized for easy installation and maintenance. System
connections are made when the rectifier is plugged into the shelf. No
additional connections are required.
“Forced” Load
Sharing
Internal rectifier circuitry will allow rectifiers to share load in the event
communication to the controller is lost or the controller malfunctions.
