Description

technical field [0001] The invention relates to a power supply device in the medical field, in particular to a power supply device for a board memory chip or a PLC controller. Background technique [0002] At present, many boards and cards used in computers, workstations, servers, medical equipment and industrial control fields on the market are equipped with RAM read-write memory chips and PLC programmable logic controllers. This RAM read-write memory chip and PLC Programmable logic controllers generally store the current system date and clock, hardware configuration information, user settings for certain parameters, and user programs. These information are saved by a disposable battery. When the battery is exhausted, After the system is shut down or the power is cut off, the information will be lost automatically, which will cause problems such as the system starts to alarm, cannot be started or cannot be used normally. Especially for the medical field, the power supply o...
