QJE PS30SWIV User manual

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. A current limiting system will protect the unit from
overloading.
6. If a short circuit occurs while outputing，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.
7. 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.
8. Do not use a car cigarette lighter in the cigarette plug
socket on the unit.
9. Before replacing a fuse make sure that the unit has been
turned off. Be sure to use the specified type of fuse.
10.Make sure the product is always suitably grounded to
prevent electric shock and to reduce noise.
11.Never disassemble，modify, and touch the inside of the
unit unnecessarily. That could cause damage to the product
and make the warranty invalid.

INSTRUCTION MANUAL

INTRODUCTION
PS30SWIV is a high efficiency ， compact ， lightweight ， high
performance switching power supply. It is also engineered to
minimize the noise specifically for the communication. Even when
the noise occurs，it can be eliminated by the Noise-Offset control.
Many convenient functions like voltage pre-set knob and a highly
visible back lit meter are all included in this standard power
supply.
