Feature:1. Integrate in One: Integrates single phase electrical phase detection, phase shifting circuit, trigger circuit and one way anti parallel one way thyristor in one, without external synchronization transformer2. Stepless Adjustment: 05VDC, 010VDC, 420mA signal automatic or manual control, achieve stepless adjustment of single phase load voltage from 0V to full voltage of grid by changing conduction angle of thyristor3. Photoelectric Isolation: Possess input and output photoelectric isolation, small size, light weight, and long life. Large control power, stepless regulation, high insulation voltage, etc.4. Automatic or Manual Control: Convenient to use the change of the input voltage to realize automatic control of load power at output, and can also use the external potentiometer(10K) to manually adjust the output power5. Wide Applicable: Widely used in industrial electric furnaces, electric ovens, lighting, primary side voltage regulation of transformers and other equipment for temperature, light, voltage regulation and other controlsSpecification:Item Type: SCR Voltage RegulatorInput Parameters: External Power Supply: No needManual Control: 10K potentiometerAnalog Quantity Control: 4-20mA, 0-5V, 0-10VLED Display: YesOutput Parameters: Minimum Conduction Current: Greater than 50mAOff State Leakage Current: Less than 10mAFrequency Range: 45-65HzTurn On Time: 10msTurn Off Time: 10msWorking Environment Temperature: -35~75.Package List:1 x Voltage Regulator(with heat sink)1 x Protective CoverNote:The resistive load is more than 2.5 times, and the inductive load is more than 4 times.
