DAQCard-1200 User Manual
Pin 49 is fused for up to 1 A but should be limited to 250 mA. The fuse is
a thermally resettable fuse which has an internal thermostat. This
thermostat opens when the current exceeds 1 A and the temperature rises.
After some time, the thermostat cools down, the switch closes, and the
+5 V is available once more. Opening this fuse does not necessarily
damage the DAQCard-1200. If you do not receive +5 V, check for any
shorts between the +5 V power pin and ground.
