Chroma 6314A

The Chroma 6310A Programmable DC Electronic Load integrates microprocessor capabilities into each load module and a mainframe to provide simple and accurate parallel operations to optimize the speed and control among multiple load modules.

All load modules may be configured to work synchronously or to test multiple outputs simultaneously, thus simulating real life applications.

The 6310A series load modules are compatible with the 6310 series mainframes (6312/6314).

In addition, the remote control commands are compatible between the 6310 and the 6310A series without needing to re-writing any remote control programs.

The Chroma 6314A 1200W and 6312A 600W DC 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 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 readback of data.

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 mode.

Modern electronic devices operate at very high speeds and require fast dynamic operation of their power providing components.

To satisfy these testing applications, the 6310A loads offer high speed, programmable dynamic load simulation and control capability.

The 6310A provides parallel control, which enables high power testing when a single module cannot meet the requirements of high power applications.

Two or more load modules can be paralleled together to achieve the desired load.

The 6310A comes with RS-232 standard for remote control and automated testing applications. USB and GPIB interfaces are available as options.

In addition, the 6310A, through its synchronized controls, provides an efficient solution for testing single output AC to DC or DC to DC converters by controlling multiple loads.

The 6310A provides the capability to test up to 8 UUTs at a time.

Each 6310A DC electronic load module has an integrated 16-bit precision A/D converter for voltage measurement with an accuracy of 0.025%+0.025% of full scale. 

The built-in resistive load current sensing circuit is capable of measuring current with an accuracy of 0.05%+0.05% of full scale.

Also, short circuit can be simulated.

All measurements are done using remote sensing to eliminate any error due to voltage drops along the measurement path.

The user can also select from a complete set of voltage and current measurements.

Modern switching power supplies are designed with over current protection (OCP) circuitry; therefore, it is important to test the OCP circuitry to make sure it is functioning within its designed specifications.

The 6310A series provides an easy and fast solution for this testing.

The 6310A DC electronic load includes a unique timing & measurement function, which allows precise time measurements in the range of 1ms to 86,400s.

This feature allows the user to set the final voltage & timeout values for battery discharge testing and other similar applications.
