LED Drivers
LED Drivers
There are two main types of LED drivers (also known as LED power supply); constant voltage (CV) and constant current (CC).
Constant Voltage
Constant voltage drivers used in LED lighting applications mainly usually have an output voltage of 12V or 24V DC. The main type of LED lighting that uses constant voltage is LED strip but some LED lamps and LED downlights also require constant voltage so it is important to check. There are many types of power supplies available, ranging from plug-in laptop style to industrial din rail mount power supplies. Although many of these power supplies will work perfectly well they are not designed for use in lighting applications and don't meet EN61347-2-13. Our latest range of Mean Well or Sun Power LED drivers are specifically designed for LED lighting applications and can even be dimmed!
Constant Current
Constant current drivers are commonly used to power LED downlights and are available in various outputs, mainly 350ma or 700ma. Most of the complete LED downlights such as the Halers H2 or EcoLED featured on our website come complete with constant current LED drivers. These type of drivers supply the LED with a constant regulated current and ensure that no over current or under current occurs thus allowing the LED(s) to perform under optimum conditions.
Efficiency
To achieve the optimum performance, maximum lifetime and efficiency from your LED driver we recommend loading to be around 70-85%.
Dimming
If you are looking to dim your LED strips or downlights, please contact us to discuss your requirements as we are able to supply a complete range of dimmable LED drivers, corresponding 1-10V dimmer switches and many other controllers. When loading 1-10V dimmable versions loading should be nearer to 100% as possible to achieve a wider dimming range.
We now also offer a rane of main dimmable LED drivers which will dim with leading edge and trailing edge switches. These are new to the lighting industry and are much easier to wire than 1-10V as you don't need to install additional cables. These drivers are available in 3 wattages; 20W, 45W and 80W, for higher loads the drivers can be synced so you could have 3x80W drivers to run a 240W load, or more if required. Another advantage of using mains dimmable LED drivers is that when using systems such as Lutron you no longer need to order the 0-10V add on unit which saves on costs.
Drivers for LED Strips
If you are unsure about which power supply to use for your LED strip runs please contact us for advice. Feel free to send us a drawing or rough sketch showing what you want to do. We will do the rest and provide you with an easy to follow wiring diagram. We also offer a great range of DMX drivers and many LED controllers including Wi-Fi for Iphone control or RF including multi channel controllers that allow multiple LED strip runs to be controlled from one remote control.
Or if you already know the length of LED strip you require then try using our power supply tables:
LED Strip 12V Power Supply Tables
| 30 LED Per Metre (7.2W Per Metre) | ||
| Length of Strip | Total Wattage | Power Supply |
| 1 to 10 Metres | 7.2W to 72W | |
| 15 to 20 Metres | 108W to 144W | |
| 25 to 30 Metres | 180W to 216W | |
| 60 LED Per Metre (14.4W Per Metre) | ||
| Length of Strip | Total Wattage | Power Supply |
| 1 to 5 Metres | 7.2W to 72W | |
| 10 Metres | 144W | |
| 15 Metres | 216W | |
| 20 to 25 Metres | 288W to 360W | |
Longer runs of colour changing strip will also require the use of an amplifier. The amplifier allows longer runs to be controlled using one controller. More than one power supply can also be used on the same run.
