What factors we should take into consideration when we purchase a 12v 24v Constant Voltage LED Driver?

1. Max Wattage

According to the National Electrical Code, LED drivers should be paired with LEDs that use 20% less than their maximum rated wattage. For example, if you have a LED Driver 100 watt that can operate a maximum of 100 watts, it should only operate LEDs that use 80 watts at most (100 x 0.8 = 80). Drivers should not be paired with an LED that is at or exceeds the driver’s maximum wattage to avoid over stressing the driver components.

2. Dimming

Both constant current and constant voltage LEDs and drivers can be made with a dimming capability. Dimmable external drivers often require an external dimmer, or other dimming control devices specified on the product datasheet (namely TRIAC, Trailing Edge, or 1-10v dimmers) to work. Smarts Electronics offers led driver triac, 0-10V LED Driver and led driver dali.

3. Ingress Protection (IP) Rating

IP ratings tell users the environmental protection that a driver’s outer casing provides. The first number specifies protection against solid objects, and the second number specifies protection against water elements. For example, according to the chart below, a driver with an IP67 rating is protected against dust and temporary immersion in water.

4. Power Factor

Power factor describes how efficiently an LED driver uses electricity. It is calculated by dividing the power being used by the driver (wattage) divided by the product of the input voltage times the current going in (volts x amps). The range for power factor is a decimal between 0 and 1. The closer to 1 the power factor is, the more efficient the driver is. A good power factor is 0.9 or above.
