What are the power requirements for using your MC-5848T four doors access control board?
Hello, the working current of a MC-5848T four doors access control board is about 200MA~350MA, and the working flow of 8 standard access control board is about 120*8=960MA, and the working current of 4 electric locks is 120MA~600MA/handle, if calculated by 4, the working current is about 2.4A, if you add them up, all currents are estimated to be around 3.5A, and the maximum output of the power supply you said is only 3.5A, then the power supply is not enough. According to the specification design power supply should provide 30~50% surplus current power supply to plan the system power. It is recommended to choose a 5A power supply, or choose a 3.5A switching power supply to provide power for the motherboard and card reader, and the electric lock is additionally equipped with a power supply for power supply. At present, due to the limited size of the chassis, we recommend using a dedicated 3.5A power supply to supply the current of the motherboard and the card reader, and then add a set of power supplies to power the lock.
