When the 4310 is running on battery power (no AC), as the battery voltage decreases, does the output voltage (on load +/-) also decrease, or does the supply try to maintain a constant output voltage?

I’m wondering if I can use a low-voltage disconnect (LVD) device like CZH-LABS D-1115A to automatically disconnect the load and prevent fully discharging the battery. It would work only if the voltage on the LVD’s input is a function of the battery voltage.

Hi eswierk,
Thank you for writing in.
When the product is running on the battery power, the battery voltage decreases and the output voltage of the product will also decrease.
So sorry that we have not tried to use a low -voltage disconnect(LVD)device for it.
We are not sure if it can work.
Beg your understanding.
Best regards

Thanks for your response.

I finally got around to setting up my system, using a CZH-LABS Electronics-Salon D-1115A low-voltage disconnect (LVD) device with the Droking 4310 UPS. The LVD is set to disconnect at 10V and reconnect automatically at 12.8V. So far it seems to work well.

Another question about the 4310: the datasheet mentions short circuit and overcurrent protection. Does this mean the device protects the battery from overcurrent if the load terminals are shorted to each other or to ground? What happens in an overcurrent condition?

Hi eswierk,
We are sorry for the delayed reply.
Regarding to your second question,We would like to tell you if overcurrent arise, the device will be damaged. That why we need overcurrent protection.
Hope this can help you.
Best regards
