CU 4000 / BP 4000
Description
The AKG charging system 4000 consists of the CU 4000 charging unit and the BP 4000 battery pack. The charging unit itself is a
Two battery packs can be charged simultaneously by the CU 4000, if the battery pack is installed in either the HT 4000 or PT 4000 transmitters. There is no need to remove the battery pack from the transmitters since these transmitters are equipped with on- board charging contacts for a
The sophisticated charging electronics of the CU 4000 comprises revolutionary functions to carefully charge and service the BP 4000 battery packs over the full lifetime of the battery.
The basic charging function is based on a trickle charge system with
Since the BP 4000 battery pack incorporates micro-
is a permanent data stream between the Charging Unit and the Battery Pack to protect the batteries from any damage caused by the charging process. A charge balance management circuit controls the exact amount of energy to be charged in the pack as the amount that was taken out of the pack (2nd level overcharge protection). The charge balance management also features a
All necessary battery pack data will be stored in the internal RAM or EPROM- memory of the pack. All predetermined and initial parameters are stored in EPROM- memory of the battery pack to perform a correct recovery cycle.
The battery pack also features an internal temperature surveillance circuit that adjusts the charging current of the CU4000 to protect the device in case of low or high temperature during loading.
To reduce the
Other controls include a
Due to the sophisticated charging system, the battery pack can power the HT 4000 and PT 4000 for up to 12 hours with one full charging cycle, plus its gentle charging function will ensure up to 1,000 charging cycles.
