The programmable slew rate makes the simulation of transient load change demanded by real life applications possible.

The built-in resistive load current sensing circuit is capable of measuring current with an accuracy of 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 user interfaces include an ergonomically designed user friendly keypad on the front panel and the following computer interfaces: The A comes with RS as standard for remote control and automated testing applications.


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 has a self-diagnosis routines to maintain instrument performance. Real time measurement of cheoma and current are integrated into each A load module using a bit precision measurement circuit.

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

Additionally, the A series offers an optional remote controller for automated production lines. The figure below shows the programmable parameters of the A modules:. For example, the test of a battery charger can be simulated easily by setting the load to operate in chrona voltage.

Chrona system is configured by plugging the user selectable load modules into the system mainframe. The figure below shows the programmable parameters of the A modules: Add to Inquiry Cart Data Sheet. It is designed for applications in research and development, production, and incoming inspection.

In addition, up to sets of system operating status can be stored in EEPROM and recalled instantly for automated testing applications. The A series will automatically detect the OCP point, making it an ideal solution for design verification as well as production line testing.


The A series offers 8 different modules with power ratings from watts to 1, watts, current ratings from 0. The waveforms programmable parameters include: The A series can simulate a wide range of dynamic loading applications.

Dynamic Loading and Control The A loads offer high speed, programmable dynamic load simulation croma control capability.

Two or more load modules can be paralleled together to achieve the desired loading. The user can perform on line voltage measurements and adjustments or simulate short circuit test using the user friendly keypad on the front panel. 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.
