The role of dual-channel power supply is as follows:
1, dual output DC regulated power supply is mainly to break the original traditional output DC regulated power supply, the use of bidirectional channel for the output of DC power supply, the advantages of it is mainly through internal integration, which makes the AC power supply into DC power supply, so that the utilization of the transformer to become high, and dual output DC regulated power supply can be used in
2, dual output DC regulated power supply and ordinary output DC regulated power supply, compared with the advantages of many, for example, it is more accurate than ordinary power supply accuracy, and can be completed independently of the energized, to a certain extent, can play a role in protecting the circuit, the role of the voltage regulator circuit, and with the continuous development of science and technology, the overall performance of the continuous enhancement.
Legal basis: "user dual power management measures" Article 1
Where a user of the same power supply point, by two or more different power supply or power supply from the company all the way to power supply, the other way by the user's own power supply (including inverted power supply), are dual power users.
