It is designed for applications in research and development, production, and incoming inspection.

The chromx is configured by plugging the user selectable load modules into the system mainframe. The user interfaces include an ergonomically designed user friendly keypad on the front panel and the following computer interfaces: The A series offers 8 different modules with power ratings from watts to 1, watts, current ratings from 0.

The loads can be operated in constant current, constant voltage, constant power and chdoma resistance and may be placed in parallel for increased current and power.


The A series can simulate a wide range of dynamic loading applications. The waveforms programmable parameters include: In addition, up to sets of system operating status can be stored in EEPROM and recalled instantly for automated testing applications. Real time measurement of voltage and current are integrated 6301 each A load module using a bit precision measurement circuit. The user can perform on line voltage measurements and adjustments or simulate short circuit test using the user friendly keypad on the front panel.

Additionally, the A series offers an optional remote controller for automated production lines. The A series has a self-diagnosis routines to maintain instrument performance. Application of Specific Load Simulation The A load modules operate in constant current, constant voltage, constant power or constant resistance to satisfy a wide range of test requirements.

Chroma 6310A Series

For example, the test of chromx battery charger can be simulated easily by setting the load to operate in constant voltage. Dynamic Loading and Control The A loads offer high speed, programmable dynamic load simulation and control capability.

The figure below shows the programmable parameters of the A modules:. The programmable slew rate makes the simulation of transient load change demanded by real life applications possible. Parallel Control The A provides parallel control, which enables high power testing when a single crhoma cannot meet the requirement of high power applications.

Two or more load modules can be paralleled together to achieve the desired loading. The A comes with RS as standard for remote control and automated testing applications. The built-in resistive load current sensing circuit is capable of measuring current with an accuracy of 0.

OCP Test By simply choosing the channel and setting the OCP parameters start current, end current, step current and dwell time from the front panel, the A series provides a chdoma and easy OCP testing solution.

The A series will automatically detect the OCP point, making it an ideal solution for design verification as well as production line testing. Add to Inquiry Cart Data Sheet.
