B&K Precision MDL400 Programmable DC Electronic Load Module, 80V/60A/400W

400W / 80V / 60A DC load module with high accuracy and maximum resolution of 0.1 mA/1 mV. Suitable for testing a wide variety of DC power sources.

The MDL Series is a multi-channel modular programmable electronic load system. Six 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 AC/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 mainftame 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.

Easily edit the load’s parameters such as voltage, current, slew rate, and width via the front panel. Increase productivity by saving your test parameters into any one of the 101 memory areas for quick system recall. Additionally, the MDL Series provides 16-bit resolution as well as numerous protection modes and a power-on system self-test to ensure the reliability of your testing.

For remote communication, the MDL series provides LAN, USBTMC compliant USB, RS232, and GPIB standard interfaces that support SCPI command protocol.

MDL252 is a dual-channel module supporting a unique flexible power configuration. The user 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).
