製品概要

概要

The purpose of the demonstration board is to promote the various types of applications where a single AC switch is controlled in on/off full-phase mode. The switch control is based on information from a single sensor evaluated by an MCU.

  • 特徴

    • RoHS compliant
    • Transil addition between TRIAC A2-G terminals
    • Overvoltage protection is not implemented on the board but some solder pads are available to implement it in two different ways:
    • Free development area with hole matrix available for application breadboard adaptation
    • 3 independent application programsHand dryer with infrared sensor and T1235H-6T switchBathroom fan with humidity sensor and ACS108 switchMulti-entrance room controller with push button and BTB08-600SW switch
    • Capacitive power supply (680 nF capacitor EPCOS B32923C36845 V ±10%Average output current: 16 mAStandby power losses < 0.3 W @ 230 V
    • Two potentiometers for setting sensor sensitivity and TRIAC turn-off delay
    • ICC connector for software adjustment
    • Varistor addition between mains voltage
    • Program selector (U2)
