The circuit adopts series-parallel, constant-current design, with
strong light and color consistency.
The current is 15 times smaller than that of peer products. Effectively avoid
fire hazards caused by high current impact.
Constant current design
DC 48V voltage drive
Ensure the transferability of the voltage, reduce the voltage drop, and
perfectly solve the uneven brightness problem of sign.
IP68 highest degree of protection
It can adapt to various outdoor harsh environments, is fully waterproof, anti-
corrosion, anti-low temperature, anti-UV, and flame retardant.
Avoid fire hazards effectively

The current is 15 times smaller than
that of peer products.
The smaller the current, the safer the
line.。
Take 1500 LEDs as an example.
Voltage: 2V~3.2V / LED,
Current: 20mA / LED .

5V：5*30=150W
12V：12*10=120W
48V：48*2=96W
Power comparison:
Conclusion:
48V LED pixel light is more
energy-efficient.
The greater the number of
lights, the greater the
environmental protection
effect.
Take 1500 LEDs as an example.
Our 48V LED save 36% energy than 5V LED
save 20% energy than 12V LED

350W power supply can drive 4500 LEDs, using 2.5 square copper wire as the mainline. Without any loops.
HSUYU DC 48V LED pixel light
Avoid problems
5V/12V LEDs, current is too large, circuit is complicated, loop must be connected to disperse the current. Many power
connections, big hidden dangers.
13. www.hsuyu.com Since 1991
Power supply can be centrally managed within 100 meters
away from the signboard Power supply is close to the signboard,
which affects the appearance and
inconvenient maintenance

HSUYU DC 48V led pixel light
Constant current drive, do not
have facula, good brightness uniformity.
Avoid:
Mixed light and color, uneven light and dark,
and dead light.
Mixed light and mottled
Pressure drop causes
uneven brightness
Inferior products cause
dead lights
15. www.hsuyu.com Since 1991
The 5V/12V LEDs has a large current at the branch joints, it is very
easy to melt or even catch fire at the moment of lighting.
The current of the main line is overloaded for a long time, the wire is
prone to aging, big safety risks.
