S1-12NV 12kW Single Phase Power Controller

Product catalog summary

Overview
The S1-12NV is a 12kW single-phase power controller designed by Power Products International Ltd. It is primarily used for controlling resistive loads in electric furnaces and HVAC systems. The controller features zero crossover switching and burst pulse control to minimize electrical disturbances.

Specifications and Characteristics

Total Rating: 12kW
Maximum Current: 52A
Supply Voltage: 230V (with a tolerance of -15% to +10%)
Frequency: 50-60Hz
Cooling: Natural Air Convection
Input Signal: 0-10V DC
Operating Temperature: -10°C to +40°C
Dimensions: 200mm (H) x 146mm (W) x 112mm (D)
Compliance: CE Compliant, BSEN50178 Build Standard

Operation
The controller regulates resistive loads by switching them on and off in time-proportioned bursts based on a 0-10V DC input signal. It uses burst fire zero-voltage switching to minimize RFI and harmonic distortion.

Installation and Safety

Install with heatsink fins vertically and allow 100mm clearance for ventilation.
Ensure ambient temperature remains below 40°C for optimal performance.
Fit a safety device to disconnect the mains supply in case of overheating.
Use ultra-fast fuses for semiconductor protection and ensure replacements are of the same type.
Insulation tests should be conducted carefully to avoid damaging thyristors.
Installation should be performed by a qualified electrician due to high voltage risks.

Input Configuration
The controller accepts a 0-10V DC input signal from a BEMS or controller to regulate current proportionally. It includes internal semiconductor fuses and provisions for external fuses if required.

Conclusion
The S1-12NV power controller is a robust solution for managing resistive loads with precise control and minimal electrical interference. Proper installation and safety measures are crucial for optimal performance and longevity.

S1-12NV 12kW Single Phase Power Controller-1

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 [email protected]

S1-12NV 12kW Single Phase Power Controller-2

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 controller...
