5-8. Zero-Volt loading application

As shown in Fig 5-8, the electronic load can be connected in series with a DC voltage source
which output voltage greater than 5V. so that the device under test that are connected to the
electronic load can be operated down to a Zero- Volt condition, the DC voltage source
provides the minimum 5V operating voltage required by the Electronic load. This application
is suitable for low voltage Battery cell with high discharge current testing.

5-9. Parallel operation

The following is a rule for a multiple output power supply connects to the 3350F series
Electronic Loads.
Rule: The potential of positive input (Red binding post) must be higher than the potential of
negative input (Black binding post) of 3350F series Electronic load.
Here is an example of outputs power supply connected to a 3350F series electronic load
Note: 1. the electronic load only may carry on the parallel operation under the fixed electric
Current pattern.
2. The electronic load do not use under series connection.
