TURN ON SETTING PROCEDURE :
The following procedure describes the use of controls and indicators for
Constant Voltage and Constant Current Mode of Operation.
CONSTANT VOLTAGE (CV) MODE :
a. Set ‘POWER ON’ Switch & keep the OUTPUT ON/OFF switch to OFF
position ( ).
b. Press LIMIT switch and adjust the VOLTAGE controls till the desired voltage is
indicated on Voltmeter ( ).
c. Press OUTPUT switch to ON position and observe that CV LED lights ( )
CONSTANT CURRENT VOLTAGE (CC) MODE :
a. Turn off the suppy. Short circuit the output terminals of the power supply
& turn on the supply.
b. Keep the OUTPUT ON/OFF switch in the OFF position ( ).
c. Press LIMIT switch and adjust the CURRENT controls till the desired current is
indicated on Ammeter ( ).
d. Press OUTPUT switch ON position and observe that CC LED lights ( ).
e. Remove the short circuit.
SET LIMIT CONTROL (VOLTAGE AND CURRENT) :
To preset the output Voltage and Current, proceed as follows :
a. Set the OUTPUT switch to OFF position ( ) ( Release Position ).
b. Press the LIMIT switch and adjust the desired output voltage with the
VOLTAGE control potentiometers ( ).
c. Release the LIMIT switch, set the OUTPUT switch to ON position and check
the output voltage on the voltmeter ( ).
d. Set the OUTPUT switch to OFF position ( ).
e. Press the LIMIT switch and adjust the desired output current limit with the
CURRENT control potentiometers ( ).
f. Release the LIMIT switch, set the OUTPUT switch to ON position and check
the output current on the ammeter ( ).
g. Set the OUTPUT switch to OFF position ( ).
h. Connect the load to the Output terminals and set the OUTPUT switch to ON
position ( ).
LOAD CONNECTIONS :
The load should be connected to the power supply output terminals using separate
pairs of connecting wires. This will minimize mutual coupling effects between loads
and will retain full advantage of the low output impedance of the power supply.
Each pair of connecting wires should be as short as possible and twisted or shielded
to reduce noise pick up. (If a shielded pair is used, connect one end of the shield to
ground and leave the other end unconnected).
