Electronic Loads
The DSO and DSOT series electronic loads are designed using advanced linear technology.The DSO series offers two main functions: constant current and constant resistance. However, these loads can absorb full power between 20% and 100% of the acceptable input voltage thanks to the autoranging mode.For more extensive requirements, we offer 'DSOT' models that also include constant voltage and constant power functions. These functions are essential for testing voltage generators such as automotive alternators or photovoltaic panels to determine their power curve. In addition, DSOT models have a basic '0 Volt' characteristic, which means they can be used with input voltages as low as 0 Volt. However, they still maintain a high reaction speed, which can reach 1V/us and 8A/us.

DC Electronic Loads
An adjustable electronic load gives the test engineer the ability to qualify designs, check production batches or service and repair electrical products. Many applications demand an adjustable electronic load. These include the burn-in of new devices along with general power supply, battery, fuel cell and generator testing.Both static and fully dynamic DC loads are offered. With dynamic functionality 2 levels of load current can be set. The rise and fall time can then be adjusted together with the time period spent at each level. The load can also be made to follow complex waveforms by tracking an external arbitrary oscillator input.
