Power Electronic
1 Summary SF-3020A 3P Meter Calibrator is designed in accordance with related national standards & regulations. Without matching an external standard meter, it can automatically or manually calibrate and test class below 0.5 single-phase & 3-phase AC/DC ammeter, AC/DC voltmeter, and power meter. Besides, it can also calibrate frequency meter, phase meter, power factor meter, transducer, power load transformer, and power relay. With standardized cabinet and featured by compact size, light weight, multi-function, high stability & automation, top reliability, easy maintenance, it is an ideal calibrating equipment for meter makers. 2 Main Feature 2.1. Digital frequency modulation, phase modulation, amplitude modulation. Intelligently designed, operation is controlled by the keyboard; 2.2. Voltage output with permanent voltage, current output with permanent current, also with fixed phase & fixed frequency; 2.3. Multi-function standard meter with power, electric energy, AC/DC voltage, AC/DC current standards; 2.4. DC output is separated from AC output; 2.5. Output voltage short circuit, output current open circuit automatically protected, and with voice & light warning; 2.6. LED display with back-light; 2.7. Adopt programming method for calibrating meter, directly display the error and print the testing result; 2.8. With software revising function for standard meter(excluding electric energy meter) 3 Main Technique Parameter 3.1.
