. . . . Preset Regulated DC Power Supply

MODEL: PPS-4A

The preset regulated DC power supply has a unique feature to preset
the voltage and current without actually loading the unit. The 16V output
power supply is completely solid state and suitable for bench operation
or 19" rack operation. It is a well regulated constant voltage voltage/constant
current supply which delivers 0- 6V at 0-4 amps and can be adjusted
continuously throughout the output range. The front panel CURRENT
control cab be used to establish the output current linit (overload) or
short circuit). When the supply is used as a constant voltage source the
VOLTAGE controls can be used to limit the output voltage. When the
unit is used as a constant current source, CURRENT controls can be
used to limit the output current. The unit will automatically cross over
from constant voltage to current mode and visa-versa if the output
current or voltage exceeds these preset limits.
