VAC9010H Ammeter Coulombmeter DC 90V 300A 12V 24V 48V 72V LCD Current Voltage Watt Meter Battery Pow

brand new and high qualityfor user to charge and discharge can be automatic identification and bidirectional current direction, no need to change direction of wiring.Aafter turning off memory function, turning off ah number, it is convenient for people to observe and measure.AH number and current reset function, do not affect measurement.Voltage, current, charging capacity ah, wh, time, energy will show at same time, too, shou all information clearly.With output and off function, flexible cab to open or disconnect output (relay need).With over voltage, over current, over power, litmited time, load protection function, etc.Can calibrate online, give a convenience for customer to correct error in time.LCD panel can be manually put out or less than 300m automatically screen out in one minute.By detecting current sensor of hall, the current through round hole of thr wire through thr sensor, both current of side direction can be detected. It is safe and convenient for users.Applicable scope: charge monitoring and discharge of electric vehicle battery, photovoltaic electricity monitoring system and so on, the first current empty charge charging needs to clean.Type: VAC9010HOptional Current: 300AScreen resolution: 0.1AVoltage measurement range: Own power supply 12-90V ; External power supply 0-90VCurrent accuracy: 3%5 wordAccuracy voltage: 2%5 wordScreen resolution tension: 0.01VScreen resolution capacity: 0.1AHScreen resolution time: 0.01H(1 min)Measurement rate: 5 times\/ secondType of protection and define(OVP): 0.01V-90VType of protection and define(OPP): 0.01W-9.99KWType of protection and define(): 0.01V-90VColour:blackMaterial:plasticSize:79x43x26mmPackage Contents:1 x Hall CoulombmeterOnly above package content, other products are not included.Note: Light and different displays may cause color of item in picture a little different from real thing.
