Description Single circuitandhigh current versions only switch, it does not include flash breathing lights. A single street light controlB dual street light controlC four way light controlD High current independent power supply The power output of Single-circuit and dual-circuit controller is 5V 1A, other devices which match the power output could be used with these controllers. High-current controller can supply power independently, the input voltage is 5v-24V,the current is 5A and instantaneous current is 10A. Four-circuit controller can supply power independently, the input voltage is 5V-24V, single-group current does not exceed 3A Single-circuit light controller: each time toggle the third channel switch or click the third channel button, the output opencloseopenclose ...... cycle Dual-circuit light controller:2-way output is always on Alpha output is on, B output is off Alpha output is off, B output is on Alpha outputs alternatively blink K2 outputs blink K2 output breathing light effect K2 output fully closed ...... cycle High current independent power supply controller: each toggle once the third channel switch or click the third channel button, the output open cycle Four-circuits light controller:Marquee mode Four-way turn flash One three, four alternate burst flash Four simultaneous burst flash, four full light, four breathing light effect Package includes: 1pc (model according to your choice)
