Data Sheet Modular Programmable DC Electronic Load MDL Series Features and Benefits Power range up to 2400 W The MDL Series is a multi-channel modular mode, which uses DSP technology to simulate Voltage range up to 500 V programmable electronic load system. Seven non-linear loads and realistic loading behavior. Current range up to 120 A different modules of programmable DC loads CC/CV/CR/CW/CZ operating modes ranging in power from 200 W to 600 W Easily edit the loads parameters such as voltage, provide users the flexibility to test a wide range current, slew rate, and width via the front panel. Removable modules for easy system of power sources from multi-output AC/DC Increase productivity by saving your test configurability power supplies to batteries, fuel cells, and parameters into any one of the 101 memory Support for up to 16 channels using dual photovoltaic arrays. areas for quick system recall. Additionally, the channel modules with mainframe extension MDL Series provides 16-bit resolution as well Operate identical modules in parallel mode The mainframe has four slots that can be as numerous protection modes and a power-on for high current applications configured with any assortment of the modules system self-test to ensure the reliability of your up to 2400 W (up to 4800 W with mainframe testing. Synchronous Load on/off function extension). The high-performance electronic load Standard LAN, GPIB, USB, and RS-232 modules of the MDL Series are capable of For remote communication, the MDL series interfaces with USBTMC/SCPI protocol support operating in constant current (CC), constant provides LAN, USBTMC compliant USB, Analog current control and monitoring voltage (CV), constant resistance (CR), constant RS232, and GPIB standard interfaces that Transient mode up to 25 kHz power (CW), and constant impedance (CZ) support SCPI command protocol.
