VAC9010H Holzer Coulomb / Color Liquid Crystal DC Two-way Voltage Current Capacity Meter Head / Band Communication

Purchase need to know: Applicable scope: electric vehicle battery charge and discharge monitoring, photovoltaic system electricity monitoring and so on, the first loading of empty load current needs to clean. 1, do you need to extend the line? The head gauge and the measuring board are 12 cm 6P line connection. If you feel the line is short, it is not easy to refit. You can buy our 2 meter extension line, so that you can extend the distance between the head indicator and the measuring board. 2,How to set battery power, fill or clear the battery capacity? First press the button will yellow the cursor to the position of OAH, press the OK button to enter the parameter setting interface, increase or smaller parameters according to the next key, after setting out click OK, parameter setting interface, yellow cursor is located in the LOP position, press the button when the Yellow cursor disappears, but according to a OK the key is to fill, press the OK key is cleared, alternating with zero. 3, a brief introduction to the protection function of instrument expansion Multi function instrument has functions of overvoltage, over current, over power, time limit, over charging and so on. It needs to cooperate with relays, and can also install simple buzzer and loudspeaker to protect simple alarm function.Details of specific protection, please read the instructions. 1. Brief introduction of instrument VAC9010HThe voltage ammeter is a kind of capablemeasureVoltage, current, chargedischargeCapacitance, timePowerA variety of physical quantitiesA new type of voltage ammeterAt the same time, the parameters can be set to realize overvoltage protection.Undervoltage protectionOver current protection, overcharge capacity protection andTime limitProtection, etc.Multiple protection functions. The instrument is usedColor liquid crystalDisplay the measured data,Display information comprehensive,Hommization. This instrument uses Holzer sensor to detect current. It is convenient and simple. It is very suitable for the output.VoltageCurrent monitoring, as well as battery charging and discharge and other applications. Two,Main characteristics 1, two-way detection of current, for the user to detect charge and discharge can automatically identify and detect bi-directional current,There is no need to change the direction of the wiring. 2. Power cut memory function. After power failure, it can remember the number of AH before power cut, so it is convenient to observe and measure. 3, time and AH count zero function, do not affect the next measurement. 4, the number of AH can be filled, and it does not affect the direct discharge measurement. 5, voltage, current, charge capacity AH number, WH number, time, power at the same time display, display information completely clear. 6, with the output shut off function key, flexibly open or turn off the output (need to match the relay). 7, with overvoltage, over current, over power, time limit, overcharge and other protection functions. 8. It can be calibrated online so that the customer can correct the error in time. 9, display the LCD screen can be extinguished manually, and can also be automatically extinguished after a minimum of one minute, you need to consult customer service frequently. 10, through the Holzer sensor detection of current, the current passing through the wire through the sensor circular hole can be detected in the positive and negative current, safe and convenient. Three. Technical indicators Plus the four pillars at the bottom can do at the bottom of the solder joint and the contact surface of the insulation, the size is 57*32*50mm; modified to remove bottom insulating pillars, the size is 56*32*44mm. Four. Connection instructions The following circuitThe diagram is a circuit in the discharge mode. When the charge is charged, the load is replaced by a charger without changing the circuit. The current direction is from the front of the transformer, the current is negative, that is, the residual quantity of the instrument is reduced; conversely, the current is positive and the residual quantity increases. 1, figure 1 is the connection mode of self power supply without relay chart1 VAC9010H power expansion board connectionExplain In use, the positive pole of the battery corresponds to the positive and negative poles of the "BAT" on the expansion board, and should not be countered. The battery is loaded into the positive pole or the negative pole line, one of which passes through the round hole of Holzer transformer, then connects the jumper cap to J4. Finally, the terminal of the positive and negative pole of the battery is connected to the "BAT" place on the expansion board, and the power is switched on. 2, figure 2 is the connection mode of independent power supply without relay chart2 VAC9010H power expansion board connectionExplain In use, batteryThe positive and negative poles should correspond to the positive and negative poles of "BAT" on the expansion board. Be careful not to answer the counter.The battery to the load line of positive or negative one through the Holzer transformer hole, then the jumper cap is connected with the J3, finally connect the battery positive and negative terminals inserted in the expansion board on the "BAT"; the external power supply is connected to the Vext, note the negative external power supply voltage range of 10-60V don't take the wrong, reverse. 3, figure 3 is a relay independent power supply connection mode chart3 VAC9010H power expansion board connectionExplain In use, it should be noted that the battery wiring should not be countered to the positive and negative poles of "BAT"..The battery to the load line of positive or negative one through the Holzer transformer hole, then the jumper cap is according to at J3, and then the relay connected, finally connect the battery positive and negative terminals inserted in the expansion board on the "BAT" the external power supply is connected to the "Vext" the external power supply voltage range, 10-60V, don't take the wrong connection. (Note: independent power supply matching relay voltage) ExplainThe relay needs to be equipped with the user, and the relay is not equipped with the relay. Five. Electronic load test pictures (1) test the 12.00V voltage when no load is available, and the instrument is in accordance with the test value of the professional instrument. (2) test the 53.00V voltage when no load is available, and the instrument is in accordance with the test value of the professional instrument. (3) the load current is 5A, the instrument is in accordance with the test value of the professional instrument, and the voltage difference is caused by the pressure drop on the wire. (4) the load current is 9A, the instrument is in accordance with the test value of the professional instrument, and the voltage difference is caused by the pressure drop on the wire.
