The PDV series LED drivers are available in 30-WATT, 75-WATT, 100-WATT, 150-WATT, 200-WATT, 300-WATT and 360-WATT versions.
Some constant voltage LED driver require you to have a 'maximum' load on them in order to dim evenly. This means that they will dim evenly regardless of the actual load on the LED driver. The Power Source PDV series of AC phase cut dimmable LED drivers have a constant voltage PWM type output. Power Supplies Australia stocks two different series of LED driver with AC phase cut dimming. Ideally you want to find a LED driver with AC Phase Cut Dimming so that it will work with your existing dimmer switch. If this is the case then you will need to find a dimmable LED driver that is compatible with the LED light fitting. It may be that the LED light fitting that you have bought only has a standard ‘non-dimmable’ LED driver in the box. If you try to use a dimmer switch with a standard ‘non-dimmable’ LED driver then the lights will go off, or may start to flicker. This means that the LED driver has built in circuitry that can detect the AC being ‘chopped’ and dim the LED light accordingly. For a LED driver to work with a TRIAC type dimming switch it needs to be an AC Phase Cut Dimming type LED driver. These work by ‘chopping’ the AC mains going into the LED driver. The dimmer switch you find in most Australian homes is either a leading-edge, or trailing-edge TRIAC type dimmer. You will need to check that your new light fitting is compatible with standard dimmer switches. If you are buying a new light fitting from a hardware store it will come complete with a LED driver. It has to be especially designed to work with a dimming switch. In fact an LED driver is an electronic device. You won’t be able to use the existing transformer with a new LED light fitting.Īlthough the LED driver does a similar job to a transformer, it does it in a completely different way. It takes the incoming 240VAC power and converts it into the required DC power for your LED light fitting. The LED driver does a similar job to the transformer on your old light fitting. If you are replacing an old light fitting with an LED light for example, replacing a halogen downlight with an LED downlight, then you will need to make sure that the LED driver is dimmable. These should work with a standard wall plate dimmer. If you are simply replacing your incandescent or halogen globes with LED globes, then you need to make sure that the LED globes you buy are marked dimmable. The short answer is yes! But there are a few things that you need to be aware of.
