10pcs DV817Y DC 7-250V 1A 5A 50A 100A 200A Digital Voltmeter Ammeter LCD Dual Display Voltage Current Meter Screen Amp Volt Gauge(100A)

AmmetersFeatures:1. LCD DC voltmeter is a generation of simple digital installed ammeter, which mainly measures voltage and current in electrical circuit in real time. LCE LCD displays measured value, and SMT chip process circuit is simple;2. Reliable and stable DC sampling true RMS measurement waveform distortion will not affect measurement accuracy;3. It is applicable to installation of voltage test sites of various specifications without auxiliary tools, and is an substitute for pointer meters;4. DV817Y LCD DC voltmeter is widely used in automation, power distribution cabinets, electrical equipment, laboratories and other occasions as long as it is used for real-time monitoring of DC voltage and current in electrical circuits and LCD direct reading display;5. product is stable and reliable, easy to install, small in size, wide in measurement range, and low in power consumption, making it an replacement for pointer meters.Parameters:Measurement accuracy: ± 1%Display resolution: 1 word at endAllowable error: full scale × (±0.5%)Refresh speed: about 3 times/2 secondsPower supply: DC 7-250V without power supply is not displayed when measuring directly below 7VWorking current: 20mADisplay mode: three position LCDEnvironment: non corrosive places with temperature of - 10-50 and humidity of 85% RHOverall dimension: 70 × forty × 28.5mmOpening size: 68 × 38mmMeasuring range:Voltage measurement: DC7-250V (1V indicates 1.00V, 10V indicates 10.0V)Current measurement: DC ± 0-200AAttention:When selecting measuring range, select appropriate measuring range according to actual needs. Don't deliberately select a large range, let alone use it beyond measuring range,If instrument is used beyond range, instrument will be burnt
