The PWM style output is a simple switching of supply ON/OFF at a rate so fast that the human eye cannot see led flickering.

Duty cycle describes the proportion of time when output voltage is on relative to the entire period of time. It is expressed

in percentage, 100% being fully on (maximal brightness) and a low duty cycle corresponding to lower brightness.

40W PWM output LED power supply

Built-in 3 in 1 dimming function. The duty of the PWM style output can be adjusted through output cable by connecting

a 0~10Vdc or 10V PWM signal or resistance between DIM+ and DIM-.

0~10Vdc or 10V PWM or resistance control dimmer
