5. Wiring Diagram:
LED Voltage Chosen:
This controller can wire to the LED lamps with a voltage ranges from 5~24Vdc if the input
voltage equals output voltage, for example:
the lamp with 5V working voltage, please use 5V power supply,
the lamp with 12V working voltage, please use 12V power supply,
the lamp with 24V working voltage, please use 24V power supply.
LED Power Chosen:
This controller can load a current ranges from 0~20A,
a 5V lamp may load a power ranges from 0~100W;
a 12V lamp may load a power ranges from 0~240W;
a 24V lamp may load a power ranges from 0~480W.
The power chosen must be 20% higher than the actual load.
The principle for power chosen: the more the better.

*
An amplifier is needed when more than 32 decoders are connected, signal amplification
should not be more than 5 times continuously.
*
connect 0.25W 90-120Ω terminal resistor at the end of each line.
If the recoil effect occurs because of longer signal line or bad line quality, please try to
