| Description | The IES5521A is a derivative of the OM1654A, but offering the extra safety feature of a nominal 1 hour time-out. This is a key safety requirement for a range of personal and home appliance applications. The time-out function will stop the triac operation and thus prevent power from being applied to the heating elements. Time-out can be accurately controlled from the AC supply frequency for a perio... |
