B&K Precision Introduces Modular DC Electronic Load for Multi-Channel DC Source Testing
Featuring Dynamic Loading Speeds Up to 25 kHz, Parallel Module Synchronization, Adjustable Slew Rates, and
Constant Impedance Mode
YORBA LINDA, CA, April 19, 2013 -- B&K Precision today announced its new MDL Series; a modular programmable DC
electronic load system. The MDL Series comprises six unique modules ranging in
power from 200 W to 600 W. Any combination of these modules can be installed
for multi-channel operation in the 4-slot MDL Series mainframe, which supports
up to 2400 W and up to 4800 W with a mainframe extension connected. Suitable
for use in industries such as automotive, solar, and electronics manufacturing,
this high performance DC electronic load system is designed for characterizing a
wide range of DC power sources, including multi-output AC/DC power supplies,
batteries, fuel cells, and photovoltaic arrays.
All DC load modules in the MDL
Series can operate in constant current (CC), constant voltage (CV), constant
resistance (CR), constant power (CW), and constant impedance (CZ) mode, which
uses DSP technology to simulate realistic non-linear loading behavior.
Depending on the module, users can select from operating voltage and current
ranges up to 500 V and 120 A. A 250 W dual-channel module supporting flexible
power allocation up to 300 W is also offered. Load modules in the MDL Series
mainframe can be synchronized and connected in parallel for increased current
With its high resolution 16-bit
measurement system, the MDL Series system supports many useful features such as
adjustable current slew rates in CC mode, transient mode operation up to 25 kHz,
and list mode programming for generating complex sequences of input changes. Up
to 101 groups of settings parameters can also be saved for executing multiple
test sequences in automatic production testing.
For remote PC control, the MDL
Series mainframe offers standard GPIB, Ethernet, USB, and RS232 interfaces
supporting USBTMC and SCPI communication protocols. The mainframe also offers a
built-in 8-pin control terminal for external triggering and synchronous load
On/Off functions. Each module includes an analog current control and monitoring
terminal for external analog programming.
Additionally, the MDL Series
provides all necessary protection functions for various testing conditions:
overvoltage (OVP), overcurrent (OCP), overpower (OPP), overtemperature (OTP),
and local and remote reverse voltage (LRV/RRV) protection.
