Output current: less than or equal to 8A/CH (Note: total current over 20A reduce the life time of the product.) Input voltage:DC12V~24V (Output power: 12V:Less than 384W, 24V: Less than 768W) Working temperature:-20-60 Celsius DMX512 standard:DMX512/1990 This decoder adopts advanced computer control chip, it can receive the - 512 standard digital control signals and converted into PWM controller signal to drive the LED. It can be controlled by the Console, and can be connected with numbers of Decoder to increase the output power to realize all kinds of changing mode. Besides, this decoder can be used as the synchronous controller to control the LED alone, it can realize the synchronous effects. This decoder adopts the digital tube to show the address code, and with 3 buttons to setting, easier to use. colour:black Material:plastic size:166 x 67 x 41mm Package Contents: 3 x decoder 6 x card plug Cautions: 1,This product only use on supply voltage DC12-24V, do not input on other voltage. 2,The lead wire shall be according to the wiring diagram of the color and label, connect correctly. 3,This product cannot be overloaded. Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
