voltage, current and power. When limit setting is finished, the voltage, current
and power setting values can only be set within the maximum and minimum
limits.
Note
Function and external analog programming are not limited by Limit.
Set the maximum and minimum voltages as follows:
1. Press the composite key [Shift] + [V-set] (Setup) to enter the Configuring
Menu.
2. Select “Source” in the menu and press [Enter] for confirmation.
Or, the user can select “Load” to set the load Limit. For load, you can only
set the maximum and minimum limits of the current and power.
3. Select Limit with Left/Right key and press [Enter] for confirmation.
4. Set the V-Max with numeric key and press [Enter].
5. Set the V-Min with numeric key and press [Enter] for confirmation.
Or, select the maximum/minimum current or power with Arrow key.
6. Set maximum/minimum current or power with numeric key or press [Esc]
to exit menu setting.
After the maximum/minimum voltage is set, the output voltage can only be
set within this range. Vmax factory setting is the rated output voltage of
corresponding model of the power supply. V-Min is 0V.
3.14 Load Function
The load function in this series of power supply extends the working range of
the power supply to make it absorb certain current and power. This is a
two-quadrant power supply, which can be switched quickly under current mode
of the power supply and the load, so as to enable speedy, continuous and
seamless switching between output and absorption current. It can be applied in
charge/discharge tests of the battery. The load is divided into internal load and
external load based on discharging capacity. For detailed specifications, refer to
Technical Specification Parameters.
Internal load
When the load function is initiated, the system is defaulted to be in internal load
mode. By default, the default value of power is power rated values. The default
value of current is small and different for each model. Please refer to the actual
value.
The user can turn on load function in the Configuration Menu. Detailed
operations are as follows.
1. Press [Shift]+[P-set] (Menu) to enter the Menu operation. The interface
displays information as follows:
DEVICE MENU
SYSTEM CONFIG INFO
2. Press the Right key to select “CONFIG” in the Menu to enter the Menu
operation and select Load-Status. Press [OK]/[Enter] for confirmation and
select the [Load] to set the load status.
3. The user can select On through Arrow key to turn on the load function.
