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.

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)

step width with 84 user programmable steps

■ Adjustable slew rate in CC mode

■ 16-bit voltage and current measurement

system providing high resolution of 0.1 mV

and 0.01 mA

■ Automatic test function

■ 101 memory locations to save/recall setting

parameters

■ Remote sense

■ OVP/OCP/OPP/OTP and reverse voltage

protection

mode, which uses DSP technology to simulate

non-linear loads and realistic loading behavior.

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.

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.
