From the world's top supplier of hot runner systems, comes the top line of temperature and valve gate controllers. Whether you want 2 zones or 640 zones of temperature control, looking to control up to 32 valves gates, or maybe control both temperature and valve gates, then the LEC and TTC family of controllers are just what you are looking for. Synventive Temperature Controller Features Triangulated Control Technology ™ All Synventive hot runner temperature controllers feature Triangulated Control Technology ™ Using this unique technology, our controllers: 1) Sense - 20 times per second, Synventive controllers precisely control the thermocouple; 2) Control - the proprietary self-optimizing Synventive PID2 control algorithm adjusts if the actual temperature deviates 0.1 F (0.05 C) from set point. The second derivative (PID2) monitors the actual temperature rate of change. As a result, the control regulates the output to the heater in advance of achieving sepoint to limit or eliminate over or undershoot. 3) Actuate - using phase angle fired output, the Synventive controller delivers smooth and exact power to each heater in 0.24 VAC increments for the ultimate in temperature control.
