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 -Vd)/R where Vd 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.
