Just connect the dimming ground wire to the center prong and the dimming wire to one side or the other choosing a side just determines what way you turn the knob to make it dim. This is the better way of dimming if you have multiple units, as the V dimmer can work with several drivers at a time.
For high voltage AC power drivers there are a couple options for dimming as well depending on your driver. Many AC driver work with V dimming, like we went over above. This is helpful as it allows LEDs to work with very popular residential dimming systems like Lutron and Leviton. The maximum number of LEDs you can run from a single driver is determined by dividing the maximum output voltage of the driver by the forward voltage of your LED s. When using LuxDrive drivers , you determine the maximum output voltage by subtracting 2 volts from your input voltage.
This is needed because the drivers need a 2 volt overhead to power the internal circuitry. For example, using the Wired mA BuckPuck driver with a 24 volt input, you would have a maximum output voltage of 22 volts. This leads us to finding what input voltage we need for our LEDs. Input voltage, after all, equals our maximum output voltage for our driver after we take into account the driver circuit overhead voltage.
Make sure you know the minimum and maximum input voltages for your LED drivers. In finding what your input voltage should be for an application you can use this simple formula.
This determines the minimum input voltage you need to provide. Now this helps us make sure the voltage works, but in order to find the right power supply we also need to find the wattage of the whole LED circuit. The calculation for LED wattage is:. Overworking the power supply can cause the LEDs to flicker or cause premature failure of the power supply. Just calculate the cushion by multiplying the total wattage by 1. So for our above example we would want at least The closest common power supply size will be 25 watts so it would be within your best interest to get a 25 Watt Power supply with a 24 Volt output.
The FlexBlock LED drivers are boost drivers which means they can output a higher voltage than what is supplied to them. This is extremely helpful in applications where your input voltage is limited and you need to get. As with the BuckPuck driver , the maximum number of LEDs you can power with a single driver in-series is determined by dividing the maximum output voltage of the driver by the forward voltage of your LEDs.
