Implementation & Wiring Information: The document provides a typical single-phase installation diagram and input configuration details. It emphasizes the importance of using internal and external semiconductor fuses for protection.

Operational & Safety Instructions:

Operation: The controller regulates resistive loads by switching them on and off in time-proportioned bursts based on a 0-10V DC input signal.
Location: Install with heatsink fins vertically and ensure adequate ventilation to maintain ambient temperature below 40°C.
Safety: Use a safety device to disconnect the mains supply in case of overheating and fit suitable fuses for cable protection.
Fuses: Use ultra-fast fuses for semiconductor protection and ensure replacements are of the same type.
Input Signal: Accepts 0-10V DC input for proportional control, operating on burst fire zero-voltage switched principle.
Insulation Tests: Proper procedures must be followed to avoid damaging thyristors during testing.
Installation: Designed for plug and play; ensure all power connections are secure before commissioning. Testing should be conducted by a qualified electrician due to high voltages.

THYRISTOR CONTROLLER DATA SHEET S1-3DR 3kW Single Phase Power Controller - DIN Rail Mounting The Power Products 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 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. • 3kW Output • PWM Control • Zero Cross Over Switching Features • Self-Powered • DIN Rail (TS35) Mounting • CE Compliant • BSEN50178 Build Standard Power Products International Limited Commerce Way, Edenbridge, Kent T: 01732 866424 F: 01732 866399 [email protected] 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 specified...
