The MDL4UB series from B&K Precision is a modular, programmable DC load in a compact 4U rack format. It is aimed at professional users in power supply testing, battery testing, research and development and factory automation. The series supports up to 16 channels (with expansion) and covers power ranges up to 4800 W.
The main features include CC, CV, CR and CW operating modes, a high-resolution 16-bit measuring system (up to 0.1 mV / 0.01 mA), an adjustable slew rate in CC mode, transient operation up to 25 kHz and an integrated list mode with up to 84 steps. The modular design allows flexible configurations with different module types, and all models support interfaces such as USB, LAN, RS232 and GPIB for easy system integration.
Module variant MDL4U200B
The model MDL4U200B is a single-channel electronic DC load module with a rated power of 200 W. It supports voltages up to 80 V and currents up to 40 A, making it ideal for testing power supply units with medium to high current requirements. The high current capacity makes it particularly attractive for applications where high currents need to be tested at low voltage.
Differences to other variants
- MDL4U102B: Dual channel with 200 W total power - more flexible channel usage, but lower current per channel.
- MDL4U400B: Single channel with 400 W - double the power in the same voltage range.
- MDL4U252B: Dual channel with 300 W - higher power with split channel operation.
- MDL4U600B: 120 A capacity - optimized for high current applications.
