THYRISTOR CONTROLLER DATA SHEET S3-54PM 54kW Three Phase Power Controller - Panel Mounting The Power Products range of S3 thyristor power controllers are designed for the control of resistive loads in electric furnaces, and heater batteries in HVAC systems. The S3 power controller series uses zero crossover switching. Burst Pulse Control ensures the load is switched only in multiples of a complete mains half-cycle in order to keep supply and electrical disturbance to a minimum. The units also feature variable frequency PWM for near infinite resolution. 0 - 10V Input Control 54kW Output PWM Control Zero Cross Over Switching AUTO / MANUAL Override Self-Powered Panel Mounting IP20 Rating CE Compliant BSEN50178 Build Standard *Other Three Phase supply voltages may be accommodated - please enquire for details Power Products International Limited Commerce Way, Edenbridge, Kent T: 01732 866424 F: 01732 866399 sales@ppi-uk.com www.ppi-uk.com

THYRISTOR CONTROLLER DATA SHEET Operational & Safety Instructions 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, and 25mm horizontally. Control panels should have sufficient ventilation (grills or louvres as required) to maintain the ambient temperature through the thyristor unit to below 40 Degrees C to run unit to...
