Product description:
UPS is the most fundamental guarantee for equipment and network systems with increasing informatization and automation. For AC and DC UPS systems, batteries are extremely important as emergency power sources. Some batteries fail prematurely due to poor materials or structures, process defects, improper use, etc. The tester can be used as a discharging load. In the online mode, it can discharge with a set constant current through continuous control of the discharge current.
