It is designed for applications in research and development, production, and incoming inspection. The system is configured by plugging the user selectable load modules into the system mainframe. 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 constant 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: slew rate, load level, duration and conducting voltage. 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 into 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. For example, the test of a 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 module 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 fast 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.

Why register? Registration allows access to the entire site including downloads of our application notes and users manuals. Versatile System Configuration The Chroma A 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. In addition, the remote control commands are compatible between the and the A series without needing to re-writing any remote control programs. 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.
