Detailed temperature control! Ideal for temperature regulation of general heating elements!

The "Toyo Paracon NP2 Series" is a three-phase two-wire control zero-cross control system. It uses a point-arc method to turn on the thyristor at zero volts of the AC power supply voltage, making it suitable for heater control near instrumentation lines that are sensitive to noise. By changing the cycle (ON time) during one cycle of the AC power supply, which is 100 cycles (2 seconds when set to 50Hz), the AC power is adjusted. 【Features】 ■ Fine temperature control ■ Zero-cross control method ■ Capable of controlling resistive heating elements such as nichrome and iron-chromium (cosθ=1) ■ Maximum allowable current: 25A to 130A (5 types) ■ Maximum load capacity: 8.6 to 45kVA (200V), 9.5 to 49kVA (220V) *For more details, please refer to the PDF document or feel free to contact us.
