Lumel-RPL1
1-phase power controller

The area of RPL1 application includes: electric furnaces and drying structures, especially industrial furnaces and tunnel cap, furnaces for annealing and brazing, and founder crucible furnaces, drying ovens, furnaces with quenching in salt baths; mechanical engineering equipment, aggregates and extruders for plastics processing, winding machines and tempering springs, spot welding and linear; production of glass and glazing, plant and equipment for drying in the infrared and ultraviolet, vats for melting glass and heating trays for forming glass furnaces; chemical and petroleum industry; radiators lining piping, wiring warming.   For power control of resistive and resistive load (transformer connected to resistive load or to rectifier circuit).  Control mode: on/off (similar to solid state relay), pulse, phase.  Amplification of input control signal (SPAN).  Limitation of load current.  Overload protection.  Signalization of exceeding the maximum temperature of radiator.  Control of 3-phase load (requires two RPL1 controller units).  External dimensions:  135 x 201 x 199 mm  135 x 231 x 199 mm (execution with fan).
