Model MDL4U102B

MDL4UB Series
Programmable DC Electronic Load Module 150 W / 80 V / 20 A

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
