CA-255 Constant Current Board Universal 10''-42" Led Tv Backlight Driver Board

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 means"brightness."
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.

GND: ground (negative)

LED +: light-emitting diode (LED strip) Positive

LED-: light-emitting diode (LED strip) Negative
