BK Precision MDL4U305-220V 500V, 20A, 300W DC Load Module, 220VAC Line InputThe BK Precision MDL4U305 is a DC load module for use with the MDL4U001 mainframe (sold separately, required for operation). The MDL4U 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 AC/DC power supplies to batteries, fuel cells, and a photovoltaic array. The mainframe consists of a controller and four open slots that can be populated with any combination of modules up to 2400 W (up to 4800 W with mainframe extension). The high-performance electronic load modules of the MDL4U 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 MDL4U 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 MDL4U Series provides LAN, USB (USBTMC-compliant), RS232, and GPIB standard interfaces that support SCPI command protocol.

MDL4U load modules

The mainframe can be populated with any combination of four modules up to a total of 2400 watts (or 4800 with mainframe extension). The MDL4U252 and MDL4U302 are dual-channel load modules. The MDL4U252 can allocate up to 250 W to either channel up to 300 W total. (e.g. 250 W/50 W, 150 W/150 W). Similarly, the MDL4U302 can allocate 300 W to either channel up to 600 W total (e.g. 300 W/300 W).
