DISCHARGE POWER SUPPLY MANUAL
MODEL DC3005, MODEL 30010, MODEL 15012
Supply and the value of 2048 was returned from the terminal program.
To convert this value to the output voltage, divide 2048 by 4095 and
multiply by 300 volts for model DC30010 power supply.
3.3 Remote Mode Analog
The Discharge Power Supply can be operated using analog.
3.3.1 ANALOG Input/Output
The Discharge Power Supply can be remotely controlled using a 0-5 volt DC
analog interface. The analog remote uses 0-5 volt signals for controlling and
monitoring the Power Supply. There is one 25 pin female D connector la-
beled ANALOG on the back of the Power Supply for connection to the analog
interface. The pin descriptions for the interface are given below in table 1.
There is a button on the front panel that can be used to switch from remote
to local control. There is also a two pin Molex connector on the back panel
labeled INTERLOCK. The pin descriptions for the interlock are also given
below in table 3-4.1.
