Connecting power
Before connecting power, make sure that the outputs are wired properly to avoid short
circuits.
IMPORTANT: When using different power supplies.
When you're using different power supplies to power the DiGidot C4 and the LEDs, it is of
utmost importance to equalize the ground potentials.
Always connect grounds (DC-) of every power supply, connected to every product that is
controlled by a single DiGiDot C4 controller, to each other.
If the grounds are not connected, this will cause malfunctioning.
Power supply
Only use a stabilized SELV rated power supply or any USB charging port that provides
500mA - 1000mA at 5Vdc to power the DiGidot C4. Note that electronic switched power
supplies usually have high inrush currents, please make sure to check all specifications
carefully and design your infrastructure accordingly.
We recommend following power supply models to power the DiGidot C4:
Mean Well APV-8-5 AC-DC Single output LED Driver
Constant Voltage (C.V.); Input 90-264Vac; Output 5Vdc at 1.4A
Mean Well APV-8-12 AC-DC Single output LED Driver
Constant Voltage (C.V.); Input 90-264Vac; Output 12Vdc at 0.67A
Mean Well APV-8-24 AC-DC Single output LED Driver
Constant Voltage (C.V.); Input 90-264Vac; Output 24Vdc at 0.34A
