Wide range high power DC electronic load - EL51000E series

The high-power electronic load EL51000E series has three voltage ranges: 150V, 600V, and 1200V. The power range is from 2kW to 48kW, and the maximum current of a single unit can reach 2000A. Through parallel expansion, the maximum power can reach 480kW. The EL51000A series load has the characteristics of high power density, high control and measurement accuracy, and high cost-effectiveness; At the same time, this series of loads has synchronous dynamic and parallel expansion functions, as well as instant triple rated power function, supporting four traditional static loading modes of constant voltage CV, constant current CC, constant resistance CR, and constant power CP, as well as three composite loading modes of CV+CC, CR+CC, and CV+CR.

The product is widely used in various fields such as power supplies, power batteries, on-board OBC/DCDC, DC charging piles, civil aviation, scientific research institutions, etc. It is a high-precision instrument dedicated to simulating load changes of various high-power products.
