Specification
Input Vol:10.8-28V
Output Vol:15-88v
size:8.5×4.5CM
1.VCC:power supply and voltage positive, circuit voltage (The voltage is usually 12V or 24V)
2.ON / OFF, ON, EN, ON_BL etc:switch foot, foot switch signal (The voltage range is between 2.5V-5V)
3. PWM, PDIM, VDAJ, BL-PWM et al:brightness adjustable feet (Dimming have two modes, one is in digital mode -PWM,
one is analog dimming -DC
4.The PWM is called pulse width adjustment, which generates a rectangular square wave signal,the frequency is generally 200HZ-2KHZ,the voltage amplitude is generally 3.3V, PDIM English shorthand, Dim meansinchbrightness.inch
The Analog dimming is by the DC voltage ,it is usually transferred directly to the foot which provide 0V-5V DC voltage to control the brightness.
5.
GND:ground (negative)
LED +:light-emitting diode (LED strip) Positive
LED-:light-emitting diode (LED strip) Negative
