A UPS made for powering DC gear is very similar to an on-line UPS, except that it does not have to have an output inverter. Also, In the event the UPS's battery voltage is matched Along with the voltage the machine demands, the gadget's power supply won't be required possibly. Because one or more power conversion actions are eliminated, this increases efficiency and operate time.
