CONNECTION AND OPERATION

WARNING ! Before plugging the unit to the AC outlet, please check that
your local supply voltage is 120 VAC.
NOTE: The DC output connector (RED + & BLACK -) has a tubular hole of
dia. 0.2"(5mm) with a set screw. For a firm connection, crimp/solder a pin
type copper terminal on the cable ends of your 12V DC device.
Ensure that the power supply's ON/OFF switch is off and it is unplugged
from the AC outlet.. Switch off your 12 V DC device and connect it's
positive and negative to the RED ( Positive ) and BLACK ( Negative )
terminals respectively. Ensure that the connections are secure and tight.
Plug the power supply into the AC outlet. Press the ON/Off switch of the
power supply to ON and observe that the neon indicator in the switch
illuminates. If the indicator fails to light , recheck the connection, AC outlet
and the fuse inside the power supply.
Your 12 V DC device may now be switched on.
COOLING (SEC-1212)
SEC-1212 is cooled by convection. Operate the unit in a cool, well venti-
lated space.
COOLING AND FAN CONTROL / THERMAL SHUT DOWN (SEC-1223)
SEC-1223 is cooled by convection and forced air. A temperature controlled
fan has been provided to improve cooling at higher loads. The fan is
Littelfuse
controlled by a sensor mounted on the power transformer. THE FAN WILL
239003
BE OFF AT LOWER LOADS. It will come on only when the temperature
21806.3
of the power transformer is above 70ºC due to higher loads. In case the fan
fails or the air flow is blocked, a second temperature sensor mounted on
the power transformer will activate over temperature shut down at 100ºC.
The output voltage will be automatically resumed once the unit cools down.
OPERATE THE UNIT IN A WELL VENTILATED OPEN AND COOL AREA.
DO NOT BLOCK THE OPENINGS AT THE FAN DISCHARGE ON THE
BOTTOM AND THE SUCTION OPENINGS ON THE SIDES .
