INSTRUCTION MANUAL
GZV4000D
SWITCHING MODE DC POWER SUPPLY
INTRODUCTION
The GZV4000D Switching Mode DC Power
Supply provides high power output with its small
size and lightweight. It is suitable for a variety
of uses, especially for DC operated radio equipment
source from an AC outlet and providing variable
voltages of 5V to 15V under 40A continuous operation.
Please read through this operation instruction carefully
and follow the instructions to prevent from abuse or
misuse. This manual must be kept for reference at
anytime in need.
FEATURES
1. Lightweight and Small Size
Switching mode power supply has the advantages of
lightweight and small size. Comparing with linear mode
power with the same power output, it is much lighter
and smaller.
2. High Efficiency
The unit is operated with efficiency of 80% under the
best condition.
3. Overload Protection
The current foldback circuitry is adopted to prevent
from overload. The overload indicator will be lighted up
when the unit is overloaded.
4. Over Temperature Protection
The over temperature circuitry is functioned when the
unit is over a certain high temperature to prevent the
unit from damage by the high temperature. When the
circuitry is functioned, the output voltage and current
will drop down to a safety value and the overloaded
indicator will be lighted up.
5. High RFI Stability
The high protection circuitry against RFI (Radio
Frequency Interference) provides a stable operation.
6. Variable Voltage Output
The variable range of output voltages from 5V to 15V
enables good fits with various uses.
7. Multiple DC Output Connections
The unit has a pair of 6A easy snap on output terminal;
a pair of full power screw-on output terminal and a
cigar-lighter type output jack.
INSTALLATION
1. Make grounding the unit to prevent from electric
shock at high voltage caused by leakage or
lightning.
2. DO NOT place the unit in high humid, dusty and/or
sunshiny places.
3. Place the unit in a location where allows free air
circulation.
4. DO NOT place the unit close the TV sets or CRT
monitor.
5. Couple with an AC outlet directly, as source via
distribution cables may heat plugs and cable.
6. Put the unit horizontally for accurate meter readings.
CAUTION
1. DO NOT use the unit for the equipment requiring
higher current input than the designed value
otherwise will damage the unit.
2. DO NOT use the unit for the lamps or motorized
equipment, which require high current input at
starting and it may damage the unit.
3. DO NOT replace the fuse before ceasing problems
and the assigned value of fuse must be used in place.
SAFETY PRECAUTIONS
MUST read through the following precautions carefully
to prevent from electric shock.
1. NEVER remove the metal cover of the power
supply while AC power is connected.
2. NEVER touch the unit when your hands are wet.
3. NEVER operate the unit if foreign materials such as
metallic objects, water, or other debris have fallen
inside. Contact your dealer for check and repair.
4. NEVER operate the unit that was being damaged, as
the voltage regulation circuitry may have been
disabled. The resulting high voltage could damage
your equipment.
5. NEVER allow foreign objects to touch the DC
Power Output Terminals.
6. If you have the need to inspect the interior of the
unit, be contained to let it cool down completely, as
some components may be enough to burn your hand
in the event of component failure.
