Buyers should recognize hidden costs of LED dimmers

By BizLED Bureau

Apr 13, 2017: Going with the trend for innovations and value for money, LED driver manufacturers usually offer added technologies like 0-10V control with dimming LED driver technology.A 0-10V control is ananalog control type, in which the interface to the LED driver  has two pairs of wires—120/240/277V line-voltage switch, also called class 1 wiring; and low-voltage dimming control wire, also known as class 2 wiring.

How 0-10V control functions

The line voltage to anLED driver is used for turning the driver on and off. A low-voltage control element like a wall switch helps the control input of the driver by altering the voltage between 1 VDC (minimum light) and 10 VDC (maximum light).The LED driver then connects this control input to a specific dimmed level of the LED light.

This opens up a complete control system of monitoring and energy- saving methods, thus, paving the way for easy installation of the control system.Power then travels from control wires to load120V or 277V circuit, which enable easy electrical design and installation.

Why manufacturers are offering it free of cost?

Majority of the manufacturers provide free dimming with the aim to sell their products.They can do so because it is inexpensive to upgrade from a switching LED driver to a 0-10V dimming driver. Nonetheless, it is a known fact that a technology always comes with a cost and, so there are hidden costs involved. Consumers should know how to identify a digitally-connected dimming driver and an analog 0-10V dimming driver, which may look easy  but in the long run,it gets complicated. If a user opts for 0-10V drivers he gets all the benefits of a normal LED dimming at no extra cost, but as said earlier, it is not actually free of cost.

The consumer should consider factors like whether the dimming performance is as per the requirements. if any extra cost has been charged for giving fresh codes and principles, etc. People usually believe that an 0-10V LED driver will facilitate all the same features as a digitally-addressable dimming driver, and,hence get surprised when they run into numerous problems.

Challenges faced with 0-10V LED dimming drivers

There are several applications where 0-10V LED dimming drivers and controls are used, for example, in areas where the quality of light need not be as significant like stairwells, parking slots, garages and outdoor lighting. In other spaces, the analog option may lead to issues that range from NEMA 410. It can also lead to increased cost as rewiring may be needed.

In the case of digitally-addressable LED drivers, it is easy to reassign and re-programme them with no extra installation or wiring charges. It is, therefore, necessary for the consumers to take out time to recognize the hidden costs involved so that they don’t end up making an expensive choice

    In 0-10V dimming, the 0-10V channel is not for delivering power. It is a control signal that tells the driver how much power to deliver. Delivering 0-10V for power would make the system enormously susceptible to line losses and your delivered power would depend dramatically on the length of line and resistance the 0-10V was delivered over.
