The EL Series is a high-density programmable DC electronic load that offers multiple voltage ranges (40V, 200V, 600V, and 1200V). It utilizes ultra-high power density technology and has a compact 4U height, capable of reaching 8.1kW. The load supports four basic operating modes: constant voltage (CV), constant current (CC), constant resistance (CR), and constant power (CP). Additionally, it supports three complex operating modes: CV+CC, CV+CR, and CR+CC.

The EL Series provides full protection features such as overcurrent protection (OCP), over power protection (OPP), overtemperature protection (OTP), overvoltage protection, and reverse alarm. It supports external control and monitoring, where a 0 to 10V input or output signal represents the full range of voltage or current. The load also offers OCP test, OPP test, and short circuit simulation to effectively meet power and automated testing requirements.

Communication interfaces include built-in RS232, RS485, and USB, with an optional LAN&GPIB communication card available. Multiple loads can be connected in master-slave parallel mode to provide higher power or current capacity. The EL Series DC load finds applications in battery discharge, DC charging stations, power electronics, and other electronic products.
