DataShuttle and DynaRes
Power Supplies
A Note on Power Supplies – The DataShuttle supplies the following voltages to power transducers, strain
gauges, etc. The currents available to the user are limited as follows:
Voltage Tolerance
Maximum Current
(mA)
Output Impedance
(ohms)
Vref(6.9V) ±5% 10 <1
+5V 4.5 to 5.0V 100 <50
+15V ±3% 10 100
-12V ±3% 10 100
Users of the open collector digital outputs and buffer amplifiers should be careful not to exceed these limits.
Any power used from these supplies will add to the specified supply current used by the DataShuttle.
*Except DS-5B models
