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 plug-in charge. 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 so-called inflection point switch-off automation. Safety switch off occurs by detection of the peak voltage, the negative voltage slope or a predetermined time out. Thus the battery pack is prevented from overcharging. An integrated two-slot power management system allows the Charging unit to charge two battery packs simultaneously in approximately 1 hour. Since the BP 4000 battery pack incorporates microprocessor- controlled surveillance intelligence, there 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 self-discharging counter used to detect the exact battery pack status after a long period of storage. With the help of this charge balance management, an accurate remaining battery life display can be realized on the transmitters (transferred via pilot tone to the SR 4000 receiver). temperature during loading. To reduce the so-called memory effect which leads to decreasing battery capacity, the communication between the BP 4000 and the CU 4000 is able to calculate if the batteries need a recovery cycle by the help of the stored date in the BP 4000. In this case, the CU 4000 draws the user’s attention to this possible problem and suggests starting a recovery cycle. The user can activate the recovery cycle via a recovery button on the CU 4000.s front panel. The recovery cycle refreshes the battery pack by charging and discharging cycles to determine the actual capacity and initialize the capacity counter for accurate use time calculation. Other controls include a 3-step LED display showing the charging status. A lockable DC connector on the rear panel of the CU allows the unit to be powered by either an external DC adapter or by the optional PSU 4000 central power supply. 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. 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 corr...
