Abstract
The utility model relates to an electric heating power regulator, comprising a power regulation module, a power regulation status indication lamp, an electric heater, a fan and a temperature switch. The three power regulation modules are connected in parallel in the circuit of the three-phase electric heater, with three power regulation status indication lamps equipped. The temperature switch controls the work of the heat radiation fan so that when the temperature of the heat radiation fins reaches the temperature of the temperature switch (55 DEG C.), the fan starts to work for the forced cooling. By adopting a power regulation module of the large power integrated electronic device having a plurality of functions such as zero-cross triggering, overload protection or the like, stepless regulation from zero to full load is implemented by the control signal of the external controller or specialized instrument. When applying to ventilation apparatuses, high-precision control with temperature accuracy within +-0.1 DEG C. is implemented in a large space, and the operation is stable and energy saving. The utility model has little harmonic wave, thus with little interference to the electric grid; is capable of directly displaying the condition of heating with signal lamps parallelly connected to the electric heater simultaneously flashing with the power of the heater.

About the protection of circuit, the power supply input should be furnished with corresponding air conservation switch; Should select for use by nominal parameter; Whether crimping is good to check each the end of a thread screw during wiring; The distribution box that installs this plate should have good ventilation, so that the heat of generation in service can in time be discharged.
Important technological parameters is as follows:
Specified input voltage: the single-phase 220V 50Hz of three-phase 380V 50Hz
Output voltage: three-phase 378V 50Hz
Maximum output current: 100A; Peak power output: 60kW
Power Regulation scope: 0-100%, control signal: 0-10VDC or 4-20mA
Main circuit control mode: a. three-phase fully-controlled; B. two-phase is controlled (one is straight-through mutually) entirely; C. control separately.
