S1-12NV 12kW Single Phase Power Controller The Spectral range of S1 thyristor power controllers are designed for the control of resistive loads in electric furnaces, and heater batteries in HVAC systems. The S1 series, like 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 and featuring variable frequency PWM for near infinite resolution. 0 – 10V Input Control 12kW Output PWM Control Zero Cross Over Switching Self Powered IP 20 Enclosure CE Compliant BSEN50178 Build Standard Specifications and Characteristics Type Number Total Rating (kW) Maximum Current rms (A) Losses (W) Supply Voltage (Vac) Frequency (Hz) Power Supply Controlled Arms Cooling Fuse Type Terminal mm2 Input Signal (Vdc) Input Impedance (ohms) Cycle Time (S) Isolation (V) Operating Temperature (0C) De rating Dimensions (mm) H W D Power Products International Ltd Commerce Way, Edenbridge, Kent T: 01732 866424 F: 01732 866399 sales@ppi-uk.com

OPERATION This power controller is designed to regulate a resistive load by switching the load on and off in time proportioned bursts according to the incoming dc signal (Factory set 0-10Vdc). LOCATION Install power controller with heatsink fins in the vertical plane. Allow a minimum of 100mm clearance top and bottom. Control panels should have sufficient ventilation to maintain the ambient temperature through the thyristor unit to below 40 Degrees C to run unit to specified kW rating. SAFETY It is essential to fit a safety device that will disconnect the mains supply from the Spectral...
