0-10V dimming technology description

2020-09-18

Control type 0-10V 0-10V is an analog lighting control standard(0 10v dimming standard). In fact, it changes a 0-10V voltage signal to control the brightness of the light. There are two 0 10v dimming standard, which are not compatible. Initially, 0-10V control was used in theaters. The lighting console provided a separate 0-10V output signal for the dimming channel of the connected 0-10v dimmer module. Another 0-10V control was used for fluorescent lamp drivers. Now popular in 0 10v dimming led driver.

 

According to the 0 10v dimming standard, when the control signal is 10V, the driver output should be 100%. When the 0-10V signal is reduced by the controller, the light will be reduced. When the signal is less than 1V, the light will be the minimum, and some drivers will be OFF. The minimum level means the minimum output of the driver. It is very important to understand the minimum value of the driver. For drives that cannot be turned off at the minimum, it is necessary to add a switch in the AC loop.

 

In addition, the current capacity of the control system is considered in the standard 60929, which stipulates that the current consumption of each driver's 0-10V signal input end is <2mA, which means that a 50mA controller can control 25 drivers.

For the 0-10V power supply of Zhongshan Dimming Lighting Electronics Co., Ltd., the 0-10V signal input terminal consumes less than 0.1mA, leading the industry.

 

The 0-10V dimming technology has existed for 15 years+. Its simple, convenient, and cost-effective features have been used until now. A device with 0-10V dimming will have a 0/1-10V signal interface, divided into +-

 

The 0-10V dimming interface is strictly divided into isolation and non-isolation. Most of the current market is non-isolated. Non-isolation: It means that the 0/1-10 interface of the 0 10v dimming led driver /traditional rectifier is connected to its own circuit, and there is no electrical isolation. It outputs a 10V voltage signal on the interface and dimming through the external connection , Realize dimming. Good: The circuit is simple. Non-isolation (sink) is usually used for small area, single room control, a dimmer is connected to multiple drives. Bad: Since the signal interface is not isolated, the more drivers connected, the increase in signal strength, which may not be controlled by the dimmer(0 10v dimming controller). Each driver has a signal output, and there is a phenomenon of signal crosstalk.
