Sobre este producto
- 1. PT4115 module integrates an internal power switch, simplifying circuit design.2. High-end current sensing technology accurately sets the average LED current, ensuring stable constant-current output.3. The pin supports analog dimming and wide-range PWM dimming, providing flexible dimming solutions.4. When the pin voltage falls below 0.3V, the module automatically enters an extremely low-current standby state.5. Output current can be accurately calculated using the formula I = 0.1/RCS.Product Parameters:Output Mode: Constant Current OutputPower Supply: DC 12V Applications: LED strips, etc.Module Testing Method:1. This is a step-down constant current board. The input voltage must be at least 1V higher than the LED's required voltage, otherwise the current will not reach the set value. For example, two strings of LEDs will light up with 6V, but not with 5V. The input voltage must be at least 7V.2. This is a constant current board, not a step-down voltage regulator. The board only controls current; the voltage automatically adjusts to the LED's required voltage. For example, if a 3V LED is connected to the load and the input voltage is 5-32V, the voltage across the LED will remain around 3V, while the voltage across the two strings will be 6V. Don't measure the output voltage under no-load conditions. The no-load output voltage is equal to the input voltage, creating a pseudo-voltage.3. The output current calculation formula is 1 = 0.1/RCS. The maximum current draw of the board can be determined by looking at the resistor values: R200 = 500mA, R330 = 300mA, and 1R = 100mA. The board only has one sampling resistor, 1R = 100mA. Two 1R resistors in parallel yield 100mA + 100mA = 200mA; one R330 = 300mA, two R330s = 600mA; R200 = 500mA, R200 + R200 = 1A, and R200 + R330 = 800mA.
