Load Function

4.1.2 Basic Operation Mode

The IT8000 series electronic loads operate in constant voltage, current, resist-

ance, or power modes to satisfy a wide range of test requirements.

• Constant Current Operation Mode (CC)

Under CC mode, the electronic load will consume constant current in regard-

less of whether the input voltage changes or not, as shown in the following

figure. The CC mode ensures that the UUT voltage outputs remain stable

when the load varies.

• Constant Voltage Operation Mode (CV)

Under CV mode, the electronic load will consume sufficient current to main-

tain the input voltage at setting voltage. As shown in the following figure. For

battery chargers or charging stations, CV mode can change their output volt-

age to ensure the precision of the charging current.

• Constant Power Operation Mode (CW)

Under CW mode, the electronic load will consume a constant power. If input

voltage rises, the input current decreases and power P (= V * I) will maintain

at setting power. As shown in the following figure.

When the UUT is a battery, the electronic load changes to simulate device

loading behavior. Many battery discharge applications and power consump-

tion profiles can be simulated for analysis, making the CW mode the best

choice for simulating electronic device loads.

• Constant Resistance Operation Mode (CR)

Under CR mode, the electronic load is equivalent to a constant resistance

and will give linear change of current with input voltage change. As shown in
