OPERATING INSTRUCTIONS

a) 1315 as AC supply :

Set output voltage to 0V by turning the variable control to
minimum position ( Anti Clockwise ).

Set Power ON switch to apply input power. Adjust the
voltage control to obtain the required output voltage at the
Blue Terminals. The variable control is a coarse control to
adjust the output voltage with in 0-30V Connect the load at
the AC output terminals. The output voltage will be 25V
after connecting 5Amp Load. The total load current should
not exceed 5 A for continuous operation.

In case of sustained overload, the overload trip operates
to isolate the power supply from the load. When the
overload is removed, the trip switch can be reset.

b) 1315 as DC supply :
Set output voltage to 0V by turning the variable control to
minimum position ( Anti Clockwise ).

Set Power ON switch to apply input power. Adjust
the voltage control to obtain the required output voltage at
the Red & Black Terminals. The variable control is a coarse
control to adjust the output voltage with in 0-40V. Connect
the load at the DC output terminals. The output waveform
is full-wave rectified and filterd DC output. The Output
voltage will be 25V after connecting 5Amp Load. The total
load current should not exceed 5 A for continuous operation.
In case of sustained overload, the overload trip operates to
isolate the power supply from the load. When the overload
is removed, the trip switch can be reset.

c) Indications :
Power ON will be indicated by Red Neon on Self
Illuminated Power ON / OFF switch. Green LED will indicate
the presence of AC output & Red LED will indicate the
presence of DC output.
