Surface-Lit AccuTab 31
Sources of Power
GTCO CalComp by Turning Technologies provides a standard wall-mount power supply, the
DP-PS12, for use in the U.S.A with the AccuTab Controller. If you want to use another wall
mount power source due to different input power requirements, it must supply the
following output voltage:
+9 VDC at 1.0 Ampere.
The following figure shows the dimensional specifications and the polarity of the power
connector.
As an alternative source of power, GTCO CalComp by Turning Technologies also offers the
capability of using the DP-UPS for 110 VAC or 90-260 VAC operation. If you want to use
another power source with the 9-pin subminiature-D connector provided on the AccuTab
Controller, it must supply the following voltages:
+5.0 ± 0.1 VDC at 1.0 Amperes
+12 ± 1.0 VDC at 100 Milliamps
Ripple on all voltages must be less than 30 millivolts.
Your power supply will need a female 9-pin
subminiature-D metal shell connector (mates to 9-pin
male D connector, indicated by the desktop power
supply icon, on the AccuTab Controller). The table below
shows the pin functions for this connector. The power
cable must be shielded, with the shield connected to the
metal connector shell at the AccuTab end and connected
to earth ground at the power supply end.
