Operational & Safety Instructions

Ensure proper installation with heatsink fins vertically and adequate ventilation.
Install safety devices to disconnect the mains supply in case of overheating.
Use ultra-fast fuses for semiconductor protection and ensure replacements are of the same type.
Accepts 0-10Vdc input signal for proportional control, operating on burst fire zero-voltage switched principle.
Follow proper insulation testing procedures to avoid damage to thyristors.

Installation
The controller is designed for plug-and-play installation. Ensure all power connections are secure before commissioning. It is recommended that only qualified electricians perform testing due to high voltage risks.

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 [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...
