Push button for Switching ON/OFF the 230 V mains supply to the
instrument.
(Variable Potentiometer) Variable potentiometer for the coarse
setting of the output voltages from the output terminals. Adjustment range
0 – 30 V.
(Variable Potentiometer) Variable potentiometer for the fine setting
of the output voltage at terminals. Adjustment range 2.1 V.
(Variable Potentiometer) Variable potentiometer for current limit
setting of the voltage source. Adjustment range 0.1 A - 3.00 A.
Output terminals for DC Power Supply “ A ” & “ B ” , 4 mm
banana plugs for connections. The Output is short circuit protected.
Dual display for voltage & current, displays the
values for both supplies A & B . When supply “ A ” is used in constant
current mode the “ A ” LED lits ,which shows that the supply A is in constant
current mode. Similarly LED “ B ” will lit , “ B ” is in constant current mode .
When the TRACK mode is selected TK LED will lit.
The instrument is provided with over voltage protection from mains
variation. The mains input voltage is selected by switch on back side. The over
voltage setting is set at 253 V for mains input voltage 230 V & 273 V for mains input
voltage 240 V. Whenever, the mains increases beyond the set voltage, it trips &
LED “ HV ” is lit. After the mains normalized, switch OFF once the instrument & then
switch ON again, if the mains is below 253 V / 273 V , the instrument get switched
ON , other wise trips again.

TRACK : When TRACK push button is pressed and the -ve terminal of A is
connected to +ve terminal of B by a shorting clamp, the power supply is
converted into tracking mode . The supply A act as a Master unit & B as
Slave unit.
