B+K Precision MDL Series - Modular Programmable DC Electronic Load
The B+K Precision MDL Series is a modular, multi-channel, programmable electronic load system. The system's mainframe has four slots that can hold any combination of MDL modules, offering a total power of up to 2400 W (up to 4800 W with mainframe extension). Seven different modules of programmable DC loads ranging in power from 200 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 MDL series modules 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.
- Modular programmable DC electronic load system: 4-slot mainframe, 4-slot extension, 7 load modules types.
- Modules offer wide voltage and current range, 0...500 V, 0...120 A.
- Support for up to 4 modules/8 channels or 8 modules/16 channels with mainframe extension.
- Transient mode up to 25 kHz.
- CC/constant current, CV/constant voltage, CR/constant resistance, CP/constant power , and CZ/constant impedance mode.
- Synchronous load on/off function.
- Adjustable slew rate in CC (constant current) mode.
- Short circuit test.
- Built-in 16 bit resolution voltage and current measurement (0.1 mV, 0.01 mA).
- Remote voltage sensing to compensate for the effect of voltage drop in wires.
- Operate identical modules in parallel mode for high current applications.
- OVP/OCP/OPP/OTP (over voltage, current, power, temperature protection) and reverse voltage protection.
- Standard Ethernet/LAN, USB, GPIB, and RS232 interfaces with USBTMC/SCPI protocol support.
