Push button for Switching ON/OFF mains supply to the
instrument.
Variable potentiometer for the coarse
setting of the output voltages from the output terminals Adjustment range 0-
30 V.
Variable potentiometer for the fine setting of the
output voltage at terminals. Adjustment range 2.1 V.
Variable potentiometer for current limit setting
of the voltage source. Adjustment range 0.1 A 5.00 A.
Output terminals for DC Power Supply 4 mm-banana
plugs for connections. The Output is short circuit protected.
Dual display for Voltage and Current. When supply is
used in constant current mode the “ ” LED lits, which shows
that the supply is in constant current mode.

NOTE : The instrument is provided with over voltage protection from mains
variation. The mains input voltage is selected by switch on back side. If the
voltage exceeds 240 V mains, it is recommended to select the 240 V tapping.
The over voltage setting for safe operation is set at approx. 270 V for mains
input voltage, when the tapping is set to 240 V. Whenever , the mains
increases beyond the set voltage , it trips and LED “ HV ” is lit. When “ HV ”
LED lits , switch OFF the instrument, and after the mains is normalized ,
switch it ON again. If the mains is below 270 V , the instrument get switched
ON , other wise trips again. If the tapping is at 230 V , and mains goes beyond
245 V approx. Instrument will trip and shows HV , in such cases use tapping
at 240 V .
