Kenwood PS Series User Manual

6-14 Current Control using External Resistor
The output current of the PS Series may be controlled from outside by con-
necting a resistor (of 0 to approx. 10 k Q).
The description below assumes that only the current is controlled using an
external resistor and others are controlled on the front panel.
Si setting
Set switches 1 and 8
DDeactivate the POWER switch ® on the front panel (switch released). Set
control switches 1 and 8 of Si © on the rear panel ON. Set al1 other
control switches OFF.
2) Connect an external resistor between pins No. 9 and No. 10 of the control
terminal block Ji © on the rear panel.
3) Activate the POWER switch ® (switch depressed). The PS Series is ready fo
operation after approx. four seconds.
4) Press the LIM key © ; set current is displayed on the ammeter (3). Vary
resistance to adjust the current of the PS Series to an intended value.
NOTE: Note that set current exceeds the rated current of the PS Series if pins
Nos. 9 and 10 of Ji are opened with Si setting shown above.
Use the external resistor in a floating condition to prevent accidents
or malfunctioning. (These pins are connected with the analog control
circuit in the PS Series.)
