LD400 and LD400P DC Electronic Loads: Voltage Dropout

Resistive discharge (conductance mode) with voltage dropout. Note that in CR mode the load performs the equation I = (V -V_d)/R where V_d is the dropout voltage.

Adjustable voltage drop-out

Some power sources, such as rechargeable batteries, can be damaged if their output voltage falls below a certain level.

The LD400 provides automatic protection by incorporating fully variable voltage dropout (CI, CR, CG and CP modes).

If the voltage applied to the load falls below a preset level, the load current is rapidly reduced to zero.
