Table 3: PDR 2000 9-Pin ‘D’ - MKS Baratron 5-Pin Phoenix Connections
Current available for +15 volts from pins 4 and 5 and for –15 volts from pins 6 and 7 is internally
protected and limited to approximately 0.75 amp total for each supply. For example, this allows CDG#1
and CDG#2 to draw 0.375 amp each; or CDG#1 may draw 0.72 amp and CDG#2 may draw 0.03 amp. If
excessive current is taken through any of the power outut pins, the internal protection will shut off the
power for the affected voltage. It will be necessary to disconnect power for thePDR 2000 for a few
minutes to allow the internal protection device to cool and reset itself.
