Model MDL400

The MDL Series is a multi-channel modular programmable electronic load system. Seven different modules of programmable DC loads ranging in power from 200 W to 600 W provide users the flexibility to test a wide range of power sources from multi-output DC power supplies to batteries, fuel cells, and photovoltaic arrays.

The mainframe has four slots that can be configured with any assortment of the modules up to 2400 W (up to 4800 W with mainframe extension). The high-performance electronic load modules of the MDL Series are 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.

*The MDL252 and MDL302 are dual-channel modules. MDL252 users can allocate 250 W to either channel up to 300 W total (e.g. 50 W/250 W, 250 W/50 W, 150 W/150 W). MDL302 users can allocate 300 W to either channel up to 600 W total (e.g. 300 W/300 W).
