Modular Programmable DC Electronic Load
MDL Series
Features and Benefits
I Power range up to 2400 W
The MDL Series is a multi-channel modular
programmable electronic load system. Seven
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 AC/DC
power supplies to batteries, fuel cells, and
photovoltaic arrays.
mode, which uses DSP technology to simulate
non-linear loads and realistic loading behavior.
I Voltage range up to 500 V
I Current range up to 120 A
I CC/CV/CR/CW/CZ operating modes
I Removable modules for easy system
configurability
Easily edit the load’s parameters such as voltage,
current, slew rate, and width via the front panel.
Increase productivity by saving your test
parameters into any one of the 101 memory
areas for quick system recall. Additionally, the
MDL Series provides 16-bit resolution as well
as numerous protection modes and a power-on
system self-test to ensure the reliability of your
testing.
I Support for up to 16 channels using dual
channel modules with mainframe extension
I Operate identical modules in parallel mode
for high current applications
The mainframe has four slots that can be
configured with any assortment of the modules
up to 2400 W (up to 4800 W with mainframe
extension). The high-performance electronic load
modules of the MDL Series are capable of
operating in constant current (CC), constant
voltage (CV), constant resistance (CR), constant
power (CW), and constant impedance (CZ)
I Synchronous Load on/off function
I Standard LAN, GPIB, USB, and RS-232
interfaces with USBTMC/SCPI protocol support
I Analog current control and monitoring
I Transient mode up to 25 kHz
I List mode (sequence mode) - minimum 20 µs
step width with 84 user programmable steps
I Adjustable slew rate in CC mode
I 16-bit voltage and current measurement
system providing high resolution of 0.1 mV
and 0.01 mA
For remote communication, the MDL series
provides LAN, USBTMC compliant USB,
RS232, and GPIB standard interfaces that
support SCPI command protocol.

* The MDL252 is a dual-channel 250 W load module supporting a
unique flexible power configuration. The user can allocate up to
250 W to either channel up to 300 W total (e.g. 50 W/250 W,
250 W/50 W, 150 W/150 W), thus replacing many dual-channel
modules with fixed power distribution.
