OPERATING PROCDURES
Output Voltage Control - It is a dual control consisting of a coarse and fine potentiometer. The final DC voltage output is the sum of both
adjustments.
Current Limiter Control - It is a dual control (coarse/fine) that changes the DC current over the rated current range.
Ground Connections - For operating with negative or positive output terminal, grounded or without grounding. Connections (+ or -) are made by
using the shorting plate at the terminal.
REMARKS: When operating this supply without being grounded, high impedance 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 load conditions change as follows:
?
Constant Voltage - The power supply will function as a constant voltage source as long as the load current is less than the current limiting
value set by the current limit operation. When the load current is equal to or greater than the current limit set, the power supply will automatically
crossover and operate as a constant source.
?
Constant Voltage Automatic Crossover - The power supply will function as a constant source when the load voltage does not equal to the
voltage value set by the output voltage control. When the load voltage equals to the value set by the output voltage control the power supply will
automatically cross over and operate as a constant voltage source.
?
Presetting Current Limiting Value - There are occasions when you will not want your load to draw too much current or want to prevent
any damage, you can preset the current limiting value as follows : Short circuit the output terminals and adjust the current limit control to your
desired value.
