DC Electronic Loads

MDL4U Series Modular Programmable Electronic Load System

The MDL4U Series is a versatile multi-channel modular programmable electronic load system designed for testing a wide range of power sources, including multi-output DC power supplies, batteries, fuel cells, and photovoltaic arrays. With seven different modules available, users can choose from programmable DC loads ranging from 200 W to 600 W, providing flexibility for various testing applications.

The mainframe features four slots that can be configured with any combination of modules, allowing for a total power capacity of up to 2400 W, or up to 4800 W with an extension. The high-performance electronic load modules utilize digital signal processing (DSP) technology to simulate non-linear loads and realistic loading behavior in four operating modes: constant current (CC), constant voltage (CV), constant resistance (CR), and constant power (CW).

The HVL Series DC Electronic Loads are designed for high-voltage and high-power testing applications, offering a wide operating voltage range up to 1000 V and high power density of up to 6 kW in a 5U form factor. These loads are ideal for evaluating DC-DC converters, batteries, battery chargers, photovoltaic arrays, and other high-power DC sources. The HVL Series supports continuous, pulse, and toggle transient operations, with transient speeds up to 10 kHz in CC mode. For scalability, up to 10 identical units can be combined in parallel to achieve total sink capabilities of up to 60 kW.

The 8600B Series programmable DC electronic loads offer high-performance testing capabilities in a compact benchtop form factor. These loads are ideal for testing and evaluating a variety of DC sources, including DC power supplies, DC-DC converters, batteries, battery chargers, and photovoltaic arrays. With transient operation speeds up to 25 kHz and high 16-bit resolution, the 8600/B Series delivers precise measurements and flexible operational modes.
