Power Supply
Weidos controllers can be powered from 11,4 to 25,4VDC requiring a minimum of 0,8A to achieve a good
performance. Polarity is NOT REVERSAL, make sure that Voltage and GND wiring (Vin+ and Vin-) are properly
connected. Make sure that power supply is not higher than 25,4 VDC.
It is necessariy to use a ferrite in Power supply wiring to avoid undesired noise in the device. See installation
instructions in Annexes.
