Description

Technical Field

[0001] The utility model relates to the technical field of power supply control, in particular to a main control module with a remote control function and a modular integrated power supply. Background Art

[0002] With the development of informatization, the requirements for power supply equipment are getting higher and higher. Not only does it require the power supply to operate stably and reliably, but it also presents diversified requirements for its functions. The integrated modular integrated power supply is required to be able to perform AC-DC conversion and DC-AC conversion, and has multiple input methods such as AC input, silicon input, and battery input. In some special occasions, it is also required to be able to perform multi-switch control, remote control, and centralized control.

[0003] The prior art has the following defects:

[0004] 1. Multiple switch controls have priority;

[0005] Most of the existing modular integrated power supplies only support 1 switch control, some support 2 switch control, and there is no 3 or more switch control; the power supply controlled by 2 switches has a sequence and a certain priority. Only when the 1st level switch is turned on, the 2nd level switch can realize power on and off control.

[0006] 2. Remote shutdown does not completely cut off the power, which will cause the battery to run out of power;

[0007] At present, the remote control of modular integrated power supplies is mostly carried out through the network. The whole machine keeps part of the circuit energized, and the power on and off control is performed by detecting network packets. However, when the modular integrated power supply is installed on a mobile vehicle, the battery is connected, and there is no mains power and other inputs. The integrated power supply will consume some electricity, and long-term non-use will cause the battery power consumption, resulting in battery power loss. Utility Model Content

[0019] Preferably, if the "switch" button is released before being pressed for 500ms, the startup cannot be completed and the system returns to a power-off state, requiring the "switch" button to be pressed again to restart.
