Series ELR 10000 3U 15kW

The device series ELR 10000 from EA Elektro-Automatik are programmable electronic loads. The devices are regenera-tive and feed the consumed DC energy back into the local or public grid with an efficiency of up to 96%. The series of-fers single-phase and three-phase models which, together with the wide input range, allow operation on practically all global mains voltages. The rated DC voltages and currents are determined by typical applications and the spectrum ranges from 0 - 80 V to 0 - 2000 V and from 0 - 6 A up to 0 - 1000 A in a single device. The DC input operates as a flex-ible input stage with a constant power characteristic (auto-ranging) and a wide voltage and current range. To achieve higher powers and currents all units are equipped with a master-slave bus. This allows for up to 64 parallel con-nected devices working as one system which can provide a load up to 1920 kW and 64000 A. Such a system works as a single unit and can use different power classes, only the voltage class must remain constant. In this way a user can construct a 75 kW system from two 30 kW 4U and one 15 kW 3U device from the ELR 10000 range. Furthermore, typical laboratory functionality is provided. This includes an extensive function generator, alarm and warning manage-ment, various industrial interfaces, software solutions and many more functions.
