| Can LEDwiz handle AC power? |

I see, is there a good tutorial on how to use the optoisolators in your setup? I'm pretty noobish when it comes to hardware but could probably pull it off if I saw it done. |

However, when powering these, it is imperative that the +V of the load is also connected to the "Bank Voltage Select" terminal respective to the driver chip from which the load is being operated. The main consideration is amperage draw, and yes, 10amps would be far too much for the LED-Wiz to drive directly. RandyT |

OK, so it looks like 500ma is the max for ledwiz right? I said 10 amps because that's what the EM pinball transformer puts out for the lamps at 6v AC. Does anyone have any experience with powering these bulbs with DC and with lower amperage? I want to keep the fixtures that are already installed on the machine and to swap them over to LEDs runs about $1.20 per bulb which is a little pricey when you start counting on the bulbs on the playfield. |

Hey Randy, thanks for clearing that up. @supafraud Definitely listen to RandyT's advice on LEDwiz topics! I could swear I posted a circuit diagram of what I used in controlling ELWire via an ledwiz through opto isolators, but I can't seem to find the topic right now. I'll keep looking. |

Believe me, I am all ears! :-) OK, so here's a question that is related but I should maybe start a new thread. I Have a Sain Smart 8 SS Relay bank that is made for arduinos. From what I can tell (and again I'm a noob so maybe I'm wrong) I just feed it 5 volts and it will switch on higher voltage AC (like for a solenoid for example) shouldn't I be able to use this with ledwiz? I'm sending 5 volts to it from USB and the led lights don't come on. I'm not sure if that's because it wants AC hooked up to it, but from what I can tell it shouldn't matter. This is the page for it: http://www.sainsmart.com/arduino-compatibles/module/relay/8-channel-5v-solid-state-relay-module-board-omron-ssr-4-pic-arm-avr-dsp-arduino.html I would love if someone smarter than me could take a gander and let me know it this would work or if i'm taking crazy pills! |
