Regin TTC40FX 3-phase 40A 230/400VAC Triac operated heater controller

Triac controller for proportional control of electric heating

TTC40FX is a proportional controller for electric heating with automatic voltage adjustment. TTC40FX pulses the whole load On - Off. The ratio between On-time and Off-time is varied 0 - 100% to suit the prevailing heat demand. The current is always switched at zero phase angle to prevent RFI. TTC40FX can control both symmetrical Y-connected 3-phase heaters and symmetrical or asymmetrical Delta-connected heaters. TTC40FX is only intended for electric heating control. The control principle makes it unsuitable for motor- or lighting control. TTC40FX is intended for DIN-rail mounting.
