Range driver
Range drivers, also known as programmable LED drivers, are a smart solution for LED lighting. They are flexible in output current and/or voltage, which means a single driver can power different types of LED fixtures. This is ideal for installers and project developers seeking flexibility and efficiency, and it helps optimize inventory. Because you can adjust the output, fewer different drivers are needed, making installation and maintenance easier and extending the life of your LED lighting.

Advantages of Range Drivers for Optimal Flexibility
Choosing range drivers offers various operational and technical advantages that contribute to the efficiency and sustainability of LED lighting installations:
- Exceptional flexibility: A single range driver can, by adjusting the output, power a wide variety of LED fixtures or modules. This simplifies project planning and execution.
- Inventory management: Fewer different driver models need to be stocked, reducing warehouse space and management costs.
- Future-proof: Easily adaptable to new LED generations or changes in lighting requirements.
- Optimal performance: Precise configuration of current or voltage ensures that the LEDs receive exactly the right amount of energy, extending their lifespan and optimizing light quality.
- Energy efficiency: Modern range drivers are highly efficient, which helps lower energy costs.
Technical Aspects and Functionalities of Range Drivers
When selecting and configuring range drivers, several technical specifications are important. These determine the compatibility, functionality, and safety of the driver within an LED lighting system.
Output Range: Adjustable Current and Voltage
The most distinctive feature of a range driver is its adjustable output range, typically specified as a range for current (mA) and a range for voltage (V). For example, a driver may have an adjustable current range from 150mA to 700mA and a voltage range from 9V to 42V. This allows the driver to be tailored to the specific requirements of various LED modules, such as downlights, panels, or spots.
Constant Current (CC) and Constant Voltage (CV) Functionality
Many range drivers are primarily designed for Constant Current (CC) applications, where they supply a fixed current to a series of connected LEDs. However, there are also hybrid models that, depending on the configuration, can operate in both CC mode and Constant Voltage (CV) mode. CV drivers provide a fixed voltage and are suitable for LED strips. Always check the product information to see which mode is supported by the driver.
Dimmable Options and Protocols
Most range drivers are dimmable and support one or more common dimming protocols, offering extended control over light intensity and the possibility for advanced lighting scenarios:
- TRIAC (phase-cut): Common in residential and smaller commercial installations. The dimmer is placed in the 230V line.
- 0-10V / 1-10V: A robust analog dimming method, often used in larger, professional projects.
- DALI (Digital Addressable Lighting Interface): A digital protocol for precise individual or group control of fixtures, including feedback and scene settings. This is the standard for complex building automation.
- Push Dim: A simple dimming method using a pulse switch.
IP Rating and Safety Certifications
As with all LED drivers, the IP rating (Ingress Protection) is important. Indoors, in dry conditions, IP20 is sufficient. For damp environments or outdoor applications, drivers with a higher IP rating (such as IP65 or IP67) are necessary. Always choose drivers with relevant safety certifications (CE, RoHS) for a reliable and safe installation.
Selecting and Configuring the Right Range Driver
Selecting and setting up a range driver requires care to ensure compatibility with the LED lighting and to achieve optimal performance.
Compatibility with LED Fixtures
Check the product specifications of your LED fixtures, paying attention to the required current (mA) and/or voltage (V) and total wattage. The range driver must be able to deliver these values within its adjustable range. A mismatch can cause flicker, reduced light output, or damage to the LEDs.
Setting the Output: DIP Switches or Software
Range drivers are configured by manually adjusting the output. The most common methods are:
- DIP switches: Many range drivers have small switches (DIP switches) that allow you to set the desired current or voltage manually—a simple and direct method.
- Potentiometer: Some drivers have a built-in potentiometer (dial) for fine-tuning the output.
- Software or programming interface: For more advanced models, especially DALI-compatible drivers, output can be set by software or a programming interface, providing more accurate control and options.
Installation Considerations
As with all LED drivers, correct installation is crucial:
- Power off: Always switch off the power supply completely before starting installation.
- Placement and ventilation: Mount the driver in a safe, ventilated place. Adequate air circulation is essential to prevent overheating and extend the driver’s lifespan.
- Wiring: Connect the 230V mains power and the low-voltage output to the LEDs correctly. Use appropriate terminal blocks and ensure correct polarity (+ and -) at the LED connection.
- Testing: After installation, check the operation and the set output.
Frequently Asked Questions About Range Drivers
Can I use a Range Driver for any LED strip?
Not for every LED strip. Range drivers are generally designed for Constant Current (CC) LED modules or fixtures. Although some models may also support Constant Voltage (CV) mode, the driver's output voltage must exactly match the required voltage for the LED strip (for example, 12V or 24V). Always check the product specifications of both the driver and the LED strip.
How do I set the output (mA/V) of a Range Driver?
The output is usually set via small DIP switches on the driver. Consult the manual specific to your driver; it includes a table specifying which DIP switch combination corresponds to which current or voltage output. Some drivers can also be configured via software or a potentiometer.
Are Range Drivers dimmable?
Yes, most range drivers are dimmable. They often support multiple dimming protocols such as TRIAC, 0-10V, DALI, or Push Dim. Always check which dimming protocols are supported by the specific driver and if they are compatible with your dimming system.
Why choose a Range Driver instead of a fixed driver?
Range drivers offer significantly more flexibility and inventory optimization. They are ideal for projects with various LED fixtures of different wattages or in situations where future changes to the lighting are expected. This reduces project complexity and logistical costs.
