Typical Applications
Three-phase Industrial Furnaces
Three-phase heating power control for annealing, sintering, quenching and drying furnaces and continuous heat-treatment lines.
Glass & High-temperature Heating
For glass melting, tank furnaces, SiC and MoSi2 elements and resistance heating loops.
Transformers & Inductive Loads
For furnace transformer primary sides, rectifier transformers and power-frequency induction furnaces, confirmed against load parameters.
FAQ
Which three-phase loads suit the TTPR?
Three-phase industrial furnaces, resistance heating, SiC / MoSi2 elements and transformer-type loads after engineering confirmation.
How to choose the rated current?
Confirm against the load’s maximum operating current, duty time, cabinet cooling and margin.
Zero-crossing or phase-shift?
Zero-crossing suits loads with high thermal inertia; phase-shift suits fast regulation or widely varying impedance. Confirm per process.
Can it connect to PLC or DCS?
Analog, digital and communication setpoints are supported; RS485 Modbus and other options depend on the model.
Can inductive loads be selected directly?
Provide transformer capacity, primary voltage, current, wiring and load variation; our engineers confirm firing and protection settings.
