Overview

The MDL4UB Series is a multi-channel modular programmable electronic load system in a compact 4U form factor. Nine 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 DC power supplies to batteries, fuel cells, and photovoltaic arrays.

The mainframe has four slots that can be populated with any combination of the modules up to 2400 W (up to 4800 W with mainframe extension). The high-performance electronic load modules of the MDL4UB Series are capable of operating in constant current (CC), constant voltage (CV), constant resistance (CR), and constant power (CW) mode.

  • Modules offer wide voltage and current range, 0 to 600 V, 0 to 120 A
  • Support for up to 4 modules/8 channels or 8 modules/16 channels with mainframe extension
  • Transient mode up to 25 kHz
  • Synchronous load on/off function
  • Adjustable slew rate in CC mode
  • LabVIEW drivers and operating software included
  • Standard LAN, GPIB, USB, and RS232 interfaces with USBTMC/SCPI protocol support
  • Short circuit test simulates a short at the input
  • 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 and reverse voltage protection

Backwards Compatibility: The MDL4UB Series modules are compatible with existing MDL4U (non B) modules and share the same mainframe. This enables users to upgrade their modules or expand their test setup without having to buy a new mainframe. MDL4U001 Mainframe
