  Dimmable led drivers From:  Huizhou Hi-zealed Electronic Co., Ltd At present, the main dimming types on the market mainly include 0-10V, PWM, R, Triac, dali\dali2, WIFI, DMX512, switch dimming, and other dimming methods. The following is a brief introduction to the dimming methods that some customers ask more about. 1 ） 0/1-10V dimmable Constant voltage and constant current dimmable modes are optional. The dimming range is 0-100%. When connected with a 0-10V dimmer, the output current can be changed by 0-10V voltage change. With active PFC correction, EMC standard design, smooth dimming, seamless compatibility with 0-10V, 1-10V, 10VPWM dimmers and lighting control system. Although it can solve the problems of efficiency and PF, the dimmer needs to be changed, and the wiring cost is relatively high. 3in1(0-10/PWM/R) led driver 2 ） PWM Through PWM wave on and off LED to change the forward current conduction time, in order to achieve brightness adjustment effect, dimming effect...

International Labour Day From:  www.hzleddriver.com      International Labor Day, also known as "May Day" or "International Workers' Day" (International Workers' Day or May Day), is a national holiday in more than 80 countries in the world.   It's on May 1 every year.   It is a holiday shared by working people all over the world.
