VAC9010 90V100A digital ammeter digital voltmeter battery charging and discharging controller
Main features
1. The bidirectional detection current can automatically identify and detect the bidirectional current for the user who detects the charge and discharge without changing the wiring direction.
2. Power-off memory function, able to memorize the AH number before power-off after power off, which is convenient for observation and measurement.
3, time and AH number clear function, does not affect the next measurement.
4. The number of AHs can be filled up without affecting the direct discharge measurement.
5, voltage, current, charge capacity AH number, WH number, time, power at the same time display, display information is comprehensive and clear.
6, with output shutdown function keys, flexible open or shut off the output (with relays).
7, with over-voltage, over-current, over-power, limited-time, over-charge protection.
8, can be online calibration, to facilitate customers to correct errors.
9, display LCD screen can be extinguished manually, can also be automatically extinguished after reaching the minimum value of one minute, need to always contact customer service.
10, through the Hall sensor to detect the current, the current through the sensor through the hole in the hole, the direction of the current can be detected, safe and convenient.

wiring instructions
The following circuit diagram shows the circuit in discharging mode. When charging, it only needs to replace the load with a charger, without changing the circuit. The current direction enters from the front of the transformer and the current is negative, ie, the remaining power of the meter decreases; otherwise, the current is positive and the remaining power increases.
1, Figure 1 is the power supply wiring without relays own power supply
Figure 1 VAC9010H power expansion board wiring instructions
In use, the positive pole of the battery corresponds to the positive and negative poles of the "BAT" on the extension board, and care must be taken not to reverse it. Insert one of the positive or negative wires from the battery to the load through the round hole of the Hall transformer, and then place the jumper cap at J4. Finally, insert the positive and negative terminals of the battery into the expansion board. BAT "At the office, you can power it on.
2. Figure 2 shows the independent power supply connection mode without relay
Figure 2 VAC9010H power expansion board wiring instructions
In use, the positive and negative electrodes of the battery must correspond to the positive and negative electrodes of the "BAT" on the extension board. Be careful not to reverse. Firstly, one of the positive and negative wires of the battery to the load passes through the round hole of the Hall transformer, and then the jumper cap is connected to J3. Finally, the terminals of the positive and negative terminals of the battery are inserted on the expansion board. BAT”; external power supply is connected to Vext, pay attention to the positive and negative external supply voltage range 10-60V, do not connect wrong connection.
3, Figure 3 is a relay independent power supply wiring
Figure 3 VAC9010H power expansion board wiring instructions
In use, pay attention to the battery wiring to correspond to the "BAT" of the positive and negative poles do not reverse. Firstly, one of the positive or negative wires of the battery to the load passes through the round hole of the Hall transformer, then the jumper cap is pressed at J3, then the relay is connected, and the terminals of the positive and negative terminals of the battery are finally connected. Insert "BAT" on the expansion board and connect the external power supply to "Vext". The external power supply voltage range is 10-60V. Be careful not to connect wrongly. (Note: Independent Power Supply Matching Relay Voltage)
Note: The relay needs to be equipped by the user. No relay is standard.
Sixth, electronic load test picture
(1) Test the voltage of 12.00V at no-load, and the instrument is consistent with the test value of the professional instrument.
(2) Test the voltage of 53.00V at no-load, and the instrument and professional instrument are the same.
(3) The load current is 5A, the instrument is consistent with the test value of the professional instrument, and the voltage value is different because of the voltage drop on the wire.
(4) The load current is 9A, the instrument is consistent with the test value of the professional instrument, and the voltage value is different because of the voltage drop on the wire.
