The US-100EP series is a 100W AC to DC LED power supply, featuring constant voltage and constant current
output design. It operates within an AC voltage range of 100 to 265VAC and offers 12V, 24V, 36V, and 48V
outputs. With a conversion efficiency of up to 94% and a fanless design, it can operate within a casing temper
ature range of -20℃ to +90℃ under natural air cooling. It adopts a thin and light long strip-shaped shell design,
suitable for light box or long strip-shaped lamp applications. It offers ultra-low no-load power consumption
(less than 0.5W), enabling the terminal system to easily meet international energy requirements.
