Basic Front Panel Operation
The Asterion DC Multioutput ASA Series power source provides extensive functionality
and programmability, which could be exercised through the front panel, and the remote
analog/digital control interface. This section provides basic details such as Navigation,
Menu selection, Rotary encoder and Soft numeric keyboard which are common to all
screens.
The Asterion DC Multioutput ASA Series power supply is shipped from the factory
configured for front panel (local) voltage/current/overvoltage Protection control, and with
the remote sense not connected (default to internal local voltage sensing at chassis output
terminals). The remote sense leads must be connected externally by the user to achieve
performance specifications. The external user interface connector (26 pin connector) is
supplied with a mating connector which has the remote inhibit input output ON/OFF control
