The BK Precision MDL400 is a single channel 80V/60A/400W optional module for the MDL001 Modular Programmable DC Electronic Load Mainframe. The MDL001 mainframe has four slots that can be configured with any assortment of the modules up to 8 channels (up to 16 channels with mainframe extension MDL002).

The high-performance MDL400 electronic load module is capable of operating in constant current (CC), constant voltage (CV), constant resistance (CR), constant power (CW), and constant impedance (CZ) mode, which uses DSP technology to simulate non-linear loads and realistic loading behavior. All panel operation and programming functions are carried out on the MDL001 mainframe panel. A wide range of dynamic loading applications can be simulated through user-programmable slew rates, load levels, duration, and conducting voltage.
