Product Detail

Description:
100% Brand New and High Quality
 
Module Name: Touch PWM dimming board

Module dimensions: length 2.2CM width 1.2CM high 0.2CM

Input voltage:
1. DC3.7 ~ 5V (actual range 3.3-5.5V). USB5V adapter suitable for 3.7V 18650 lithium batteries, lithium-ion battery.
2. DC 12V-24V

Maximum output current: DC 2A
This module features:

Without direct contact with the copper foil, can be separated by 3mm of acrylic glass or plastic touch dimmer.
Purpose: to control the LED light module, lights, and other products. Suitable for indoor lamp, LED lighting dimmer, DIY lights dimming optimum conversion circuit board.
The use of capacitive touch principle, namely the induction sensitive fingertips. Touch the lights turn on, turn off the lights in touches, is an electronic switch.
A switching function, dimming function, with memory slowly fades brightness LED light touch stepless dimming function. When the lights brighten slowly, slowly dimmed lights, effectively avoiding eye irritation. PWM stepless dimming
Wiring Method: PCB board (V +, V-) for power input, (L +, L-) for connection of plus or minus grade LED lights (TP) is connected to touch the antenna (note the wiring is not too long, after qualifying with a small brass Available sensing area of leather), copper area suggestions about 1x2.5cm.
Click bright touch (touch duration is less than 550ms), you can achieve the lights off control. One-click touch, lights; again tap the touch, the lamp is off. Illumination lighting of the initial luminance is fixed at 90% full brightness.
Long press the touch (touch duration greater than 550ms), you can achieve stepless dimming the lights. A long press touch, light levels gradually increase light levels when released after the release time parked in the corresponding brightness, long time if more than three seconds, the light levels to achieve maximum brightness does not change
Once again, long press the touch, light levels gradually decreased light levels when released after the release time parked in the corresponding brightness, long time if more than three seconds, the light levels to a minimum brightness does not change. This cycle .......
Tips:
If false triggering when debugging or not triggered, may cause the following reasons:
1) Touch line is too rough
2) Touch line is too long
3) copper is not big enough
4) close to the switching power supply terminal interference
5) Touch parameters C1 unreasonable
Note: Constant dimmer output connected LED, resistor must limit string! LED can be purchased at less 12 ohm resistor in series with a current limiting resistor calculation: R = (Vi - Vled) / Io
Wherein, Vi is the input voltage, Vled is the total pressure drop of all the LED lamps, Io is the total current light strings. Should consider the floating range Vi, Vled the calculation. Generally, when the battery is fully charged Vi will be too large. After the LED heat up, Vled will drop! Prevent excessive current damaging modules or lights.
Package Included:
1x Capacitive touch dimmer PWM control panel
