Chroma 6310A Programmable Electronic Load integrates
microprocessor capabilities into each load module and
mainframe to provide simple and accurate parallel operation to
optimize the speed and control among multiple load modules.
All load modules may be configured to work synchronously, to
test multiple outputs simultaneously, thus simulating real life
applications.
The 6310A load modules operate in constant current, constant voltage,
constant power or constant resistance to satisfy a wide range of test
requirements. For example, the test of a battery charger can be simulated
easily by setting the load to operate in constant voltage.

6310A System Block Diagram
Each load module is designed with state-of-the-art technology and
connects all the power MOSFET devices in parallel to insure high accuracy
load control with a minimum drift of less than 0.1%+0.1%F.S. of the
current setting. Chroma's use of FET technology provides minimum input
resistance and enables the load to sink high current even at very low
voltages. For example, the model 63103A is capable of sinking 60A at 1V,
and well-suited for testing the new 3.3V low voltage power supplies. Low
voltage operation, down to zero volts, is possible at reduced current levels.
The 6310A load module uses a photo coupler for isolation between the
The 6310A series load modules will be compatible with the
6310 series mainframes (6312/6314). In addition, the remote
control commands will be compatible between the 6310 and
the 6310A series without needing to re-writing any remote
control programs.

multiple output switching power supplies and multiple DC-DC converters.
There are also higher wattage modules that may be mixed and matched
for an even more versatile system. Additionally, the GO/NG output port
is useful for UUT's pass/fail testing on an automated production line. All
modules on the 6314A/6312A mainframe share a common GPIB address
to synchronize and speed up the control of the load modules and the read-
back of data.
module load design
The Chroma 6314A 1200W and 6312A 600W electronic load
mainframes accept the user-installable 6310A series load
modules for easy system configuration and will mount in a
19" instrument rack. The 6314A holds up to four 63102A load
modules, which will result in an 8-channel 100W/channel load
with standard front-panel inputs. This makes it ideal for testing
