Series PUB 10000 4U-6U 10-60 kW

The bidirectional DC laboratory power supplies in the PUB 10000 series from EA Elektro-Automatik are two quadrant devices which can perform the function of a power supply (source) as well as that of an electronic load (sink). In sink mode the device is regenerative and feeds the energy back into the local grid with an efficiency of up to over 96%. The PUB 10000 series are 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 - 60 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 (auto-ranging) with a wide voltage and current range. To achieve higher power and current all units are equipped with a Mas-ter-Slave bus. This enables up to 64 parallel connected de-vices to be combined into one system which can provide up to 3840 kW and 64000 A. Such a system works as a single unit and can use different power classes start from 5kW, only the voltage class must remain constant. In this way a user can construct a 150 kW system from two 60 kW 6U and one 30 kW 4U device from the PUB 10000 range. Fur-thermore, typical laboratory functionality is provided. This includes alarm and warning management, various option-al industrial interfaces, software solutions and many more functions.
