Market Demands
- No longer use relays
- Heaters of 1.5kW to 3kW use 16A to 30A triacs
- Heaters > 3kW use 30A to 45A triacs
- Adjustable Heating Power by zero DC full/half cycle skipping guarantees low EMI
- Continuous high current capability
- Electronics must be able to withstand continuous high temperatures
- High power application requires careful attention to triac and heatsink design
