GROUND CONNECTION
Depending on the application, the power supply output terminals
can be grounded in any one of the following grounding conditions :
Negative ground – black (-) negative terminal is shorted with green
GND terminal.
Positive ground – red (+) positive terminal is shorted with green GND
terminal.
Floating ground – green terminal is not shorted with any of the
output terminals.
REMARKS
When operating this power supply as a floating ground, high imped-
ance leakage can exist between the power supply circuitry and the
chassis ground.
Basic Mode of Operation
This power supply is designed to operate as a constant voltage source
or as a constant current source. Automatic crossover to either mode
of operation occurs when the load condition changes as following :
CONSTANT VOLTAGE (CV), AUTOMATIC CROSSOVER &
CONSTANT CURRENT (CC)
The power supply functions as a constant voltage source (CV) as long
as the load current is less than the preset current limiting value. When
the load current is equal to or greater than the preset current limiting
value, the power supply will automatically cross over to the constant
current mode, voltage will drop, (CC) will show on the LCD display
panel and it will operate as a constant current source.
When the load current drops below the preset current limiting value, the
supply returns to constant voltage (CV) mode.
