The EL51000E series of high-power electronic loads have three voltage ranges of 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 240kW. Mainly for server power supply, A/D power supply, power electronic components, power batteries, on-board charger OBC/DD modules, DC charging pile modules, DC charging piles, current devices (relays, fuses, connectors) and other product tests use.
The EL51000E series load has the characteristics of high power density, high control and measurement accuracy, and cost-effective "three highs"; at the same time, this series of loads have the functions of synchronous dynamics, parallel expansion, etc., and provide three times the rated power instantly. The EL51000E series supports constant There are four traditional static loading modes: voltage CV, constant current CC, constant resistance CR, and constant power CP. It also supports three composite loading modes of constant voltage CV + constant current CC, constant resistance CR + constant current CC, and constant voltage CV + constant resistance CR.
Products are widely used in power supplies, power batteries, new energy vehicles, DC charging piles, civil aviation, scientific research institutions and other fields. It is a high-precision instrument dedicated to simulating the load changes of various high-power products.
