1. Unparalleled application Flexibility with digital technology Field configurable phase-angle or zero-crossing or mixed-firing(phase angle+zero-crossing) for improved application flexibility on site. Adjustable soft start for application flexibility.2. Heater and control diagnostics capabilities Monitor actual heater and control performance and help eliminate initial start up problems3.Non-harmonics Zero-crossing mode generates minimal harmonics, and virtually eliminate the possibility of interference with other electronic equipment.4. Saving power rate, because of non-ineffective power Zero-crossing mode can save 10~15% of power rate, because does not generate ineffective power during controlling heater.5. Multi function Over-load detecting, Heat sink over-temperature detecting Fuse-SCR-load fault detecting, Load initial conditions detecting6. Serial communication with RS-232 Remote control setup,computer control and monitoring of load status.
