Energy regulation is a message that has been the loudest over the past few years. Many people are well aware of the energy savings and long shelf lives linked with LEDs (light-emitting diodes). However, a lot of people are not attuned to the fact that the innovative light sources need specific devices, known as an LED driver transformer to function. The LED driver offers LEDs with the right amount of electricity to perform and function at their best. In a nutshell, an LED driver transformer converts high voltage (AC) to low voltage (DC).
WHY LEDS NEED LED DRIVER TRANSFORMER
- Typically, LEDs are formulated to operate on a low 12-24 voltage. However, the majority of areas supply high voltage of about 120-277V. A LED driver transformer regulates the high voltage to low voltage.
- The LED driver transformer insulates the LEDs from voltage fluctuations. An abrupt change in voltage could lead to an alteration of voltage being conveyed to the LEDs. LED light output corresponds to its voltage or current supply. LEDs are designed to function well within a particular range (calculated in amps). A little or a lot more current could instigate light output to degrade faster or fluctuate because of extremely high temperatures within the LED.
FACTORS TO CONSIDER WHEN CHOOSING A LED DRIVER TRANSFORMER MAXIMUM WATTAGE
An LED driver transformer should be matched with LEDs that utilize a little less than the maximum wattage. That essentially implies that drivers should not be paired with an LED which surpasses the driver’s maximum wattage. This also prevents overstressing the driver accessories.
Power factor illustrates how well an LED driver uses electricity. The power factor range is a decimal between 0 and 1. If the power factor is closer to 1, that means the driver is efficient.
Constant-voltage and constant-current can be designed with a dimming ability. For that assertion to be true, both LED drivers and LEDs must categorically state that they can be dimmed on the product data sheet. If the data sheet doesn’t provide that kind of information, suffice to assert that the product isn’t dimmable.
IP (INGRESS PROTECTION) RATING
Ingress Protection rating informs consumers the kind of protection the driver’s exterior casing offers. The 1st number outlines protection against solid objects while the 2nd against water elements.
PHYSICAL SHAPE AND SIZE
A good rule of thumb when buying a LED driver transformer is to indulge an expert who will inform you about the right product to fit your chosen area. Enlisting the services of an expert will go a long way in helping you avoid unscheduled maintenance and purchase costs.
