ZERO-VOLT LOADING CONNECTION
The Electronic Load can be connected in series with voltage sources that can accommodate the minimum operating
voltage and line voltage drop so the Electronic Load can test the devices at its full current capacity down to a zero-volt
level.
Important Notes:
1. The boost power supply used for Zero-Volt Load Operation must handle up to the maximum operating current of
the application.
2. The power rating of the Load Bank will decrease based on the amount of power dissipated at the boost power
supply.
3. A protective diode rated for the maximum operating current of the application will need to be placed across the
power terminals of the DUT.
4. A boost power supply with minimal noise specification is recommended for zero-volt load operation.
