OPERATING INSTRUCTIONS
a) 1315D 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. The variable
control is a coarse control to adjust the output voltage with
in 0-30V Connect the load at the AC output. The output
voltage will be 25V after connecting 5A Load. The total load
current should not exceed 5A 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) 1315D 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 DC output. The output voltage will be 25V
approx after connecting 5A 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) Panel Meter :3 Digit DPM will read voltage & current of
AC/DC outputs by selecting the Push Switch on the front
panel to monitor respective Voltage & Current.
d) Indications :
Power ON will be indicated by illuminated ON/OFF Switch.
