> 5.25 V PWR LED = Off; (power fault)
4.75 V < V
ext
< 5.25 V PWR LED = On
User output voltage range Available at +5V screw terminal 4.65 V min., 5.25 V max.
User output current available Available at +5V screw terminal 10 mA max
Note 8: Voltage specification applies at barrel plug power input. The power supply provided with the board
meets this specification at the rated total power supply current. If a different power supply is used,
small line resistances could cause significant voltage drop between the power supply and the barrel
plug input.
Note 9: This is the total current requirement for the WEB-TC which includes up to 20 mA for the LEDs and
10 mA for the user voltage output.
