What is the difference between 1-10V dimming and 0-10V dimming?

Time:2021-05-18  /  Read:4621

At present, the commonly used dimming mode can be divided into 5 categories: SCR dimming, 0-10V dimming, PWM (Pulse Width Modulation) dimming, Resistance dimming, DMX512 dimming, DALI dimming.The 0-10V dimming includes 1-10V dimming.This paper mainly analyzes the difference between 0-10V dimming and 1-10V dimming and its working principle.


0 to 10 v dimmer

In a dimming system, "0-10" uses a controller to adjust the voltage on the dimming light. Simply put, the control signal is a DC voltage that varies between 0 and 10V. At 0V, the light is dimmed to its minimum brightness, but usually a switch is required to turn it off completely.

For customers who pay attention to dimming performance when low output, it is recommended that all 0-10V dimming should use a shielded line, which is grounded at the controller end.Because unshielded 0-10V dimming lines are subject to radiated interference like antennas (from transformers, radio transmitters, motors, etc.), this will cause the lights to flicker

1-10 v dimmer

1-10V is a stable and reliable dimming method for low voltage lamps.The way it works is actually pretty simple.Each lamp has its own separate transformer (driver) to control the lamp.One is the darkest level, and ten is the brightest.When the dimming signal voltage is at 1V, the dimmer is darkest, and the lamp is off between 1V and 0V.If it is 0-10V dimming, 1V will still be bright.

1-10V dimming power supply

The dimming effect of 1-10V dimming power supply has a good safety guarantee. It is linked by transistors to achieve light, and there will be no light flickering phenomenon.

In real life, 1-10V dimming power supply has a very significant role.1-10V dimming power supply can effectively help adjust the whole system, and achieve energy saving and environmental protection effect.



What is the difference between 1-10V dimming and 0-10V dimming?

The main difference between 0-10V and 1-10V is the direction of the current between the dimmer and the driver.0-10V conduction at 0.3V;When 1-10 V is turned on at 0.7-0.8 V, the bulb will not be able to turn off completely.Most Bluetooth controls used for energy-saving retrofit projects will require a zero off drive, that is, a 0-10 V dimming.For example, somewhere in Canada with only 347 V, there are controls available, but no relays, so they need the driver to have "dimming".0-10V signals are sensitive to external interference.

0-10V wires should not be routed next to power cables or placed next to potential noise sources.0-10V is mostly used for recreational lighting, 1-10V is mostly used for general lighting.
