IES5521A Description
The IES5521A is a derivative of the OM1654A, but offering the extra safety.
IES5521A Key Features
- Time-out function stops triac operation after a set time
- Reset time-out by turning mains supply off and on
- Low external ponent count
- Constant ON cycle time, with proportional OFF time
- All ON cycles consist of an integral number of mains cycles
- No DC ponent in the mains supply
- On chip circuit protection against triac gate spikes
- Low supply current requirement
- Sensor AC powered, thus minimising DC supply and filtering needs
- Separate power supply input, allowing easy gate pulse width adjustment
