PAB 70-1 A
REGULATED DC POWER. SUPPLIES
The PAB-A Regulated DC Power supply
is an automatic
constant-voltage/ constant-current transfer type of cower
supply with an auto-range display meter (3—1/2 digits,
liquid crystal display).
The output voltage and output current can be displayed by
selecting them with the switch on the front panel. An
external voltage also can be displayed with the meter as an
input terminal for such signal is provided on the front
panel (except the PAB250-0.25A and PAB.350-Q.IA which have
no external voltage measuring function).
The control circuit is a monolithic IC based circuit. It
employs a temperature compensation type of reference diode,
metal film resistors of excellent temperature coefficient,
and wire wound potentiometers, thereby realizing stable,
The output switch is an electronic switch which causes no
chattering or other noise and which can be electronically
When the output switch is off, the output voltmeter
indicates the value corresponding to the voltage setting
knob, facilitating the voltage preset operation.
The FINE VOLTAGE setting control can be changed to that for
current setting control by changing the internal connector
setting. The PAB 11O-O,6a, PAB250-0.25A and PAB350-0.1A have
no FINE VOLTAGE setting contrοl.
The operation mode is clearly identified between the CV mode
(constant- voltage mode) and the CC mode (constant-current
mode) with the LEDs on the front panel.
In order to be usable as a system component of an automation
system, the PAB-A Series Power supply
has on its rear panel
the remote-control terminals for control of the output
voltage or output current with an external control voltage
signal. The full-scale adjustment can be accomplished from
the front panel. The remote/local selector switch, which is
convenient for adjustment and maintenance of the power
supply when it is used as a system component of an
automation system, is provided underneath the output
terminals (binding post terminals).
