Beware of Zero-Crossover Switching of Transformers
... It takes perhaps a millisecond or more for the circuitry to react. Therefore, the load switch may not be fully on until load voltage is perhaps 15 to 20 volts. In this event, surge current isn’t as great, but it is still potentially destructive. Also, a random turn-on SSR may, at times, turn on at o ...
