  • Page 2: High Voltage Safety Precautions

    [8] Be sure to wear insulated gloves when handling is required during operation. After Use [9] The ROHM Evaluation Board contains the circuits which store the high voltage. Since it stores the charges even after the connected power circuits are cut, please discharge the electricity after using it, and please deal with it after confirming such electric discharge.
  • Page 3 This evaluation board outputs a zero cross signal from 90 Vac to 264 Vac input. The evaluation board is mounted with BM1Z002FJ which outputs high precision zero cross timing of targeted AC voltage. BM1Z002FJ will provide power less down to 1/10 of what conventional zero cross signal generator circuit consumed.
