High Quality DC 100V 10A Voltmeter Ammeter Blue + Red LED Display Amp Dual Digital Volt Meter Gauge Current Detector | Инструменты

Features:

*1. This measuring range of this voltmeter is 0-100V. This voltage is just measurement signal, which can't be regarded as voltmeter's working power supply. 

*2. This voltmeter need external working power supply which can supply DC4.5-30V.

*3. The measuring circuit and power circuit's negative pole are communal.

*4. The voltage of this voltmeter's working power supply is 4.5-30V. 30V is the maximum operating limited voltage, please leave enough margin to avoid permanent damage caused by electrical spark，power supply ripple or excessive abrupt change of voltage. 

*5. It is NOT moisture-proof, waterproof, shockproof, anti-oil, please be careful when using.

*6. Notice: 50A/100A must be connected to current divider, otherwise there is the danger of burning.
