Series ELR 10000 2U 1,5-3kW

The device series ELR 10000 from EA Elektro-Automatik are programmable electronic loads. The devices are regen-erative and feed the consumed DC energy back into the lo-cal or public grid with an efficiency of up to 96%. The series offers single-phase and three-phase models which, togeth-er with the wide input range, allow operation on practically all global mains voltages. The rated DC voltages and cur-rents are determined by typical applications and the spec-trum 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 flexible input stage with a constant power characteris-tic (autoranging) 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 connected devices working as one system which can pro-vide 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. Fur-thermore, typical laboratory functionality is provided. This includes an extensive function generator, alarm and warn-ing management, various industrial interfaces, software solutions and many more functions.
