MDL4UB Series Programmable Electronic Loads Mainframe

Description

MDL4UB Series Multi-channel Modular Programmable Electronic Loads System from B&K Precision

The MDL4UB Series is a multi-channel modular programmable electronic loads system designed in a compact 4U form factor. It offers nine different types of programmable DC load modules that range from 200 W to 600 W, giving users the flexibility to test various power sources, including multi-output DC power supplies, batteries, fuel cells, and photovoltaic arrays.

MDL4UB Series Mainframe includes a controller and four open slots, allowing for any combination of modules up to a total of 2400 W (and up to 4800 W with a mainframe extension). The high-performance electronic load modules can operate in four modes: constant current (CC), constant voltage (CV), constant resistance (CR), and constant power (CW).

Users can easily adjust the load parameters—such as voltage, current, slew rate, and width—via the front panel. To improve productivity, users can save their test parameters in any of the 101 available memory slots for quick recall. Additionally, the MDL4UB Series features 16-bit resolution, multiple protection modes, and a power-on system self-test to ensure stable and reliable operation.

For remote communication, the MDL4UB Series supports LAN, USB (USBTMC-compliant), RS232, and GPIB standard interfaces, all of which are compatible with the SCPI command protocol.

Modules Comparison

Populate the mainframe or mainframe extension with any combination of four modules from the below options.

* The MDL4U102B, MDL4U252B, MDL4U302B, and MDL4U502B are dual channel modules where total power is allocated between channels. For example, the MDL4U102B can allocate a maximum of 150 W to either channel up to 200 W total (e.g. 150 W/50 W, 100 W/100 W, 50 W/150 W).

Backwards Compatibility:

The MDL4UB Series modules are compatible with existing MDL4U (non-B) modules and can share the same mainframe. This allows users to upgrade their modules or expand their test setups without needing to purchase a new mainframe.
