Note: In this configuration, it is recommended to always switch on the power source DC Input
on first and then the DC input of the load.
Stage 1:
Discharge of the battery to 24V
Setup: Voltage on the power supply set to 24 V, DC Input of power supply and DC input of load
activated
Reaction: The e-load will load the battery with a maximum current of 100 A in order to
discharge it to 24 V. The power supply delivers no current at this moment, because
the battery voltage is still higher than what is set on the power supply. The load will
gradually reduce the input current in order to maintain the battery voltage at 24 V.
Once the battery voltage has reached 24 V with a discharge current of approx. 0A,
the voltage will be maintained at this level by charging from the power supply.
Note: The power supply determines the voltage setting of the load via the Share bus. In order
to avoid deep discharge of the battery due to accidentally setting the voltage on the
power to a very low value, it is recommended to configure the under voltage detection
feature (UVD) of the load, so it will switch off the DC input when reaching minimum
allowed discharge voltage. The settings of the load, as given via the Share bus, cannot
be read from the load’s display.
Stage 2: Charge the battery to 27V
Setup: Voltage on the power supply set to 27 V
Reaction: The power supply will charge the battery with a maximum current of 40 A, which will
gradually reduce with increasing voltage as a reaction to the changing internal
resistance of the battery. The load absorbs no current during this charging phase,
because it is controlled via the Share bus and set to a voltage still higher than the
actual battery voltage and the actual output voltage of the power supply. When the
voltage reaches 27 V, the power supply will deliver only the current needed to
maintain the battery voltage.
