Description:
The battery tester with regenerative energy recovery in the BT 20000 series from EA Elektro-Automatik are two quadrant devices which can perform the function of a charger as well as that of an electronic load (discharging). In discharging mode the device is regenerative and feeds the energy back into the local grid with an efficiency of up to over 96%. The BT 20000 series includes three phase units which, together with the wide input range, allows use with practically all global mains voltages. The DC voltages and currents are determined by the application and the spectrum ranges from 0 - 10 V to 0 - 2000 V and from 0 - 40 A up to 0 - 1000 A in a single device. The DC supply operates as a flexible output stage with a constant power characteristic (autoranging) with a wide voltage and current range. To achieve higher power and current all units are equipped with a Master-Slave-Bus. This enables up to 64 parallel connected devices to be combined into one system which can provide up to 1920 kW and 64000 A. Such a system works as a single unit and can use as a battery module tester or as a battery pack tester. In this way as an example a user can construct a 150 kW battery pack tester system from five 30 kW 4U units BT 20000. Furthermore typical battery tester alarm and warning management, various industrial interfaces, software solutions and many more functions are available. |
