2.1.2 Input/Output Connection

A power supply capable of supplying 2 A must be connected to TP1 and TP4. The LED load has 3 options to choose from:

  1. For 2 IR LEDs, the jumper J1 needs to be connected.
  2. For 1 white LED, the jumper J2 needs to be connected.
  3. The jumper J3 is for external LEDs load.

Wires must be twisted and kept as short as possible to minimize voltage drop, inductance, and EMI transmission. TP5 are the input terminals for the PWM dimming signal. The PWM frequency range is 20 kHz to 200 kHz.

Once the connection is ready, apply the input voltage first, then apply the PWM signal.
