Detailed introduction
Uninterruptible power supply is the most basic guarantee for all operating equipment and network systems with increasing information and automation. Whether it is an AC or DC uninterruptible power supply system, batteries play an important role as a backup power supply in the system. Usually, the battery is in a floating charge standby state. Once the AC power fails or other accidents occur, the battery becomes the energy supplier for the load.
Functional characteristics
Adopting single-cell monitoring module: compatible with 2V/6V/12V single-cell voltage monitoring:
Online compensation discharge function: during online discharge, the host displays current = battery pack discharge current = host internal dummy load current + actual load current. Since the actual load current will change with the change of online voltage during online discharge, the host internal dummy load battery will also automatically adjust to ensure that the battery pack is always discharged in a true constant current mode;
Multiple-cell voltage shutdown thresholds can be set: multiple lagging single-cell batteries can be found in a continuous and uninterrupted discharge test. Supports parallel connection of multiple small constant current expansion modules to meet the needs of larger discharge current. The host can control the constant current module to start and stop at the same time;
Adopting aviation alloy electric heating elements: high electric heat conversion efficiency, low power consumption, high safety factor, small size and light weight;
Intelligent identification program, the host can automatically determine whether the single-cell monitoring is the clip falling off or the threshold is actually reached, avoiding the interruption of the discharge process by human factors and other unexpected factors;
Flexible power supply mode: using AC and DC power supply modes, more applicable.
