DC-UPS module

This is a high efficiency DC UPS power module, designed for the needs of DC backup power applications. The module supports the wide range of input voltage, lead-acid batteries, lithium ion, lithium polymer, lithium iron phosphate battery as a backup battery, has perfect charging management function, at the same time onboard automatic lifting pressure regulator circuit, DC power supply voltage can be provided directly to the device after. When switching between the input power and the battery, the output voltage is stable, and the load operation is not affected. When the input power supply is charged, the module is charged to the battery, and the power supply to the power supply device after the output voltage is regulated at the same time. When the input power is cut off, the module automatically switches to the battery power supply, and the power supply to the device is provided with a voltage stabilized voltage, and the switching time is zero, and the load operation is not affected. When the battery power supply, the board MCU can monitor the battery voltage in real time, when the battery discharge to the set voltage threshold voltage, the power supply automatically turns off the output, and enters the low power consumption sleep mode. The power supply can be started only when the input power is restored or the battery voltage is restored to the threshold voltage.
