The CU 4000 revolutionizes battery management for wireless systems. The heart of the supply system is the BP 4000 rechargeable battery pack with built-in active monitoring circuitry. An integrated microprocessor continuously monitors battery status and accurately calculates the remaining battery life. This puts an end to the nightmare of batteries failing in the middle of a performance. A processor controlled pulse charging system charges the battery pack quickly yet gently, and the integrated "Charge Balance Management" feature makes sure that only as much energy is fed to the battery pack as had previously been drawn from it. In addition, several monitoring circuits and a temperature sensor prevent the battery pack from being overcharged.

Note: Product shown in image is for illustrative purposes only - actual product is charging station ONLY; handheld and bodypack transmitters NOT included. 

A self-discharge counter does not only measure battery discharge during operation but also determines the charge level after prolonged storage periods. As charging begins, the BP 4000 circuitry sends all relevant data to the CU 4000 charger to "tailor" the charging process exactly to the needs of the battery pack. To eliminate memory effect, the CU 4000 automatically checks whether the battery pack needs a recovery cycle and automatically starts the cycle after the user has confirmed the start command. The charger provides two dedicated compartments for charging two HT 4000 or PT 4000 transmitters or two battery packs at the same time. The BP 4000 plus CU 4000 system is an investment that will quickly help reduce battery cost and reduce environmental hazards from used batteries.
