Equipped with a high-performance microprocessor

in every mainframe and module, the MDL Series

programmable DC electronic load utilizes a

parallel architecture that provides a high

measurement speed. Additionally, a simultaneous

load on/off operation can be performed through

the front panel, analog control terminal, or remote

SCPI command. This configuration allows the

system to control modules synchronously and

increases productivity in testing.

The tools you need

Hi gh per formance architecture

With removable module design, you can choose

suitable load modules to modify the system

according to your requirements. This design

allows for multiple channels and is ideal for

testing several units, especially power supplies

with multiple outputs. At the same time, all load

modules can be configured to work independently.

All load modules, including the high power 500

W and 600 W modules can fit in one slot. Unlike

competitor models that require two slots for high

power modules, the MDL Series offers a one-slot

form factor for all modules.

Mod ular d esig n

The MDL Series can execute multiple test

sequences across all channels. Sequences can be

cascaded, and each step can be programmed

with upper and lower limit values. When applied

in automatic production testing, you can easily

judge whether the test parameters of your

devices are within the specification limits and

adjust your process according to the GO/NG

verdict.

Automati c test mode

The MDL series can operate at low voltages for applications such as fuel cell and solar cell testing.

Low Vol tag e Operation

The MDL Series mainframe offers all the latest

options to the user for remote communication.

Connect via GPIB, Ethernet, USB, or RS232 to

carry out data communication through SCPI and

USBTMC standard communication protocols to

control all your electronic load modules from a

PC.

Powe rful communi cation interfaces

Transient operation enables the module to

periodically switch between two load levels.

A power supply’s regulation and transient

characteristic can be evaluated by monitoring

the supply’s output voltage under varying

combinations of load levels, duty cycle, and slew

rate. The MDL Series can simulate these

conditions up to 25 kHz.

Tr ansi ent operation

List mode

In constant current mode, users can control the

rate or slope of the change in current in a

transient response test. Set the slew rate to as

depending on the module and selected current

range.

Adj ustable sl ew r ate

Not limited to just switching between two levels,

list mode lets you generate more complex

sequences of input changes with several different

levels. Up to 7 groups of list files can be saved

in the mainframe. Each list can contain up to 84

step.
