Re: LDD Drivers, why and how?

Got some confirmation. The current draw by the LDD's from the PS will vary depending on the number of LED's attached to the LDD. Total wattage drawn from the PS is what counts. So, a half loaded LDD-1000 will only draw about ~450 mA from the power supply and will supply 1000 mA to the LED's at what...

Re: LDD Drivers, why and how?

What is the difference between Maximum amps for chassis wiring and Maximum amps for power transmission? Which should we reference for wiring our LEDs? Its in the article. None of this is written in stone and the numbers are all quite conservative but when it comes to a fire in my house I tend to er...

LDD Drivers, why and how?

For wire choice you need to consider the length of the run and how much current will be through it. Then choose a safe gauge wire to handle it and give you the least voltage drop. Didn't realize this was important. How can we determine the right gauge wire? Very important. For one, you don't want t...

LDD Drivers, why and how?

Well, I can't claim to know how the inner workings of the drivers work but, though they do get warm, it's not 40watts worth of heat. Think of it in terms of the drivers you are currently using... You could think of them as a "normal" power supply with 1 LDD connected. Your "normal&quo...

LDD Drivers, why and how?

Right, the LDD-1000 will supply 1000 mA regardless, but the current it pulls from the 48V power supply will differ depending on how many LED's are on the driver, since the voltage is always fixed from the power supply, correct? So, we would not be limited to 7 LDD-1000's as long as they are not ful...

Re: LDD Drivers, why and how?

Thanks for the reply. I do have basic electrical knowledge, but hadn't dug into specifics yet. I'm still trying to decide if I want to bother with the changeover from the ELN drivers or not. Nothing is set in stone. :D So, will a LDD-1000 driver pull 1000 mA regardless of the number of LED's connec...

LDD Drivers, why and how?

You are going to run into no end of troubles if you don't start reading the data sheets for the hardware you choose and doing some research into basic electrical knowledge but I will try and help you out a bit... Do these use the 10v PWM or the 5v PWM expansion? --Colin LDD drivers are 5v PWM. I ema...

Stuggling with the LDD Drivers

The LDD drivers and the controlling device MUST share a common ground. You can't just send them a signal and have them work, they need to be properly hooked up electrically.
