The signal input which can be 0-10V or PWM signal dimmable driver is helpful for a variety of reasons. The dimming signal is carried by an extra pair of wires in these signal input dimmers. The signal uses a variety of protocols, including 0-10/1-10V, DMX, DALI, and a variable resistor. These signals can be connected to the driver through a pair of control wires separate from the DC output or AC input.
The 0-10V dimmer, which may be supplied with a rotary knob or a vertical slider, readily connects to the power supply’s two dimming wires. As a result, it gives your LED strip light, smooth, and effective dimming capabilities.
PWM is an abbreviation for pulse width modulation. PWM has several applications, one of which is dimming and regulating LED lights. If you’re using a signal input dimmable driver, make sure the output is PWM. A PWM allows for a wide range of brightness by altering the amount of time the signal is ON or OFF. Unlike analog dimming, the PWM signal cannot be both ON and OFF at the same time. In other words, an LED will receive either full voltage or no electricity at all.
PWM dimming solves the challenge of load matching. This implies that you will always have constant and full-range dimming independent of the driver capacity and/or load. It also allows for equal dimming levels by using different size drivers controlled by the exact driver. This means that a 100W driver can operate an 80W load, and a 120W driver can work an 80W dimming at the same pace.
PWM not only achieves a lower dimming level, but also a much more accurate dimming for LED strips.
Compared with Meanwell’s HLG/ELG solutions, Upowertek PWM dimming does not have any problems of “dead-travel or dead trip” of dimmers. For example, a 100W constant current driver drives a 100W LED strip, then there is no dead trip issue, however, in most of the common applications, we may use a 100W driver to drive 70W strip, for example, then the constant current driver output is 70W even though the dimmer output is higher than 7V until 10V thus the real adjustment range is 0-7V. If the load is smaller, the dead trip area is wider thus it makes the dimming experience very uncomfortable. But for a 100W PWM dimmable constant voltage driver, when the dimming voltage is 10V, the output of the driver is 70W as 100% load level and goes down linearly and smoothly with the dimming voltage until very low.

Smooth Dimming Effect
Do you have a 48V output constant voltage LED driver
Yes, we have 12V, 24V and 48V constant voltage LED drivers, the output power ranges from 60Watt to 400Watt.
What’s the output frequency of your PWM output drivers
It's 4kHz. At such high frequency output, there isn't any flicker, it's safe for human healthy.
Does your CV dimmable driver have a dead trip issue
No, we use PWM output technology, the dimming effect is very smooth.
