Power Supply: DC: 5V, or AC: 7-12V, or AC: 120V-500Vmeasurement display Frequency range: 50HZ±10% Output voltage: 200mv or 600V Output current: 1A or 5A (user specified) Range expansion: with shunt or transformer Power consumption: ≤1.5VA Accuracy: 0.2%±3 characters LED: highlight 0.56 display, one second’s data update Over range indication: 1 or -1 Display range: 0-1.999 Overload: for continuous 1.2 times, and for instantaneous: voltage 2 times/5S, current 5 times/5S. Isolation voltage: 2KV/50HZ/1min Insulation resistance: ≥100MΩ Average working time without breakdown: ≥5000H Working conditions: temperature: -25℃~55℃; relative humidity: ≤93% with no corrosive gas Altitude: ≤2500MTime aging: all the products have been time-aged, so that it can stably work in a long-term to reduce the impact of external environment on the meter, offering users a satisfactory product.
1. Should be used in the temperature range: -25℃~55℃, humidity: ≤80%, to prevent undesirable phenomena caused by temperature changes.
2. Take care of vibration and shock
3. Do not use it in places with dust, gas and chemicals harmful for electrical products.
4. If the abnormal voltage is caused by the magnetic field, high frequency devices, high voltage spark, lightning and etc, please use the external power line filter or non-linear resistors to interfere and absorb the circuit.
5. The signal input line should be as short as possible, and protective shielding wire should be used in places where there may be interfering signals. It is recommended to use twister pair in general conditions.
