CAUTION
1.
Even though the chassis of the unit is negatively
grounded，use correct terminals to connect cable.
2.
When plugging the unit into a wall outlet，it must be turned
off.
3. Place the unit in a dry and well ventilated area.
4.
Never touch the unit while it is working. Even though it is
designed for high efficiency，the unit will still get hot.
5.
If a short circuit occurs while operating the unit，the unit
will be protected by a short circuit protection function.
Turn off the unit and repair the cause of the short circuit
immediately，then turn it back on.
6.
Do not use the unit for devices that require high current
input at the start，such as motorized equipment. Do not use
the unit to charge a car battery.
7. Do not use a car cigarette lighter element in the cigarette
lighter socket on the unit.
8. Before replacing a fuse make sure that the unit has been
turned off. Be sure to use the specified type of fuse.
9. Make sure the product is always suitably grounded to prevent
electric shock and to reduce noise.
10.
Never disassemble ， modify or touch the inside of the unit
unnecessarily. That could cause damage to the product and
make the warranty invalid.

INTRODUCTION
CSI23SWI is a highly efficient，lightweight，high performance
switching power supply designed in a small footprint chassis.
It is well shielded to reduce Radio Frequency Interference at
close range. It has the small footprint of popular radio
transceiver. It has constant current protection, over
temperature protection and output Over Voltage Protection(OVP)
to ensure better reliability and safer protection to both the
power supply and its connected load. There is one main DC
output at the rear and a front mounted cigar socket to provide
convenient DC connectivity. It has excellent line and load
regulation, low ripple and noise.
PART NAMES AND FUNCTIONS
1.
Power switch：Turns the unit on and off.
