    Need help to find out how to provide a constant power supply to several device. It is from AC power supply to DC and the DC supply will supply to approximate 10 digital lock.

    If the digital locks are separated by some distance then there is no way to get a constant voltage at each point. In industrial control we distribute a DC voltage along the network cable. The DC supply is nominally 24 Volts. Then the nodes are specified to work at any voltage from 11 VDC to 25 VDC. The allows a node to be close to a "hot" supply or up to 500 meters away on a "weak" supply.

    What are the dimensions of your digital lock network with respect to power distribution?
