Spectral - Thyristor Controllers
The Spectral range of thyristor power controllers are designed for the control of heater batteries in HVAC systems and resisitive loads in electric furnaces. All spectral controllers are self-powered and require a 0-10volt input signal. Available in single and three-phase versions, the units comply with current EMC and safety regulations are CE compliant and built to BSEN 50178. As with most PPI thyristor assemblies custom options are available

The Spectral range of S3-54 and S3-86 thyristor power controllers rated at 54 and 86kW repectively are designed for the control of resistive loads in electric furnaces, and heater batteries in HVAC systems. All Spectral controllers uses zero crossover switching, and burst pulse control ensures the load is switched only in multiples of complete mains half cycles thus keeping supply and electrical disturbance to a minimum. Variable frequency PWM provides near infinite resolution.
