Jtron 3-digit AC 500V 10A Voltage Current Meter Module - Black
Precautions: 1. This table uses the capacitor step-down design principles£¬ because the higher the frequency the smaller the impedance of the capacitor£¬ it is not suitable for use in high-frequency electronic speed control£¬ non-mains frequency sine wave£¬ or other high-frequency components of the occasion£¬ or else easy to burn !!! 2. The instrument wiring sequence is: first connect the current loop line£¬ 220V voltage finally connected£¬ after turning on the 220V power supply£¬ the instrument will not be able to touch any components and circuits behind£¬ to avoid electrical shock hazard. Key indicators: 1. Accuracy: 1% ± 2 words 2. Display: 0.39 inches of LED digital display£¬ voltage - red£¬ Current - Green 3. Measurement speed: approximately 2 times per second 4. Dimensions: 70 x 40 x 30 mm 5. Installation size: 68 x 38mm 6. Power line£¬ measuring line length: about 150mm 7."Split" transformer wire length: about 100mm Extreme working conditions: 1. Working temperature: -10~+ 50'C 2. Operating Humidity: 10~80% (non-condensing) 3. Working pressure: 80~106kPa 4. Sunlight: no direct exposure
