[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 signal indicating when there is a zero voltage crossing from an input AC voltage from 90 VAC to 264 VAC. The BM1Z002FJ with the very few external components, will output a signal which is synchronous and offset in time if configured to do so, indicating when the two phases of the input AC signals are crossing 0V relative to one another.
