Taidacent Modbus RTU Power Monitor Energy Meter with RS485 TTL Isolated 100V 5A 10A 50A 100A DC Voltage Current Meter with Dual LCD Display (100V50A_Modbus Protocol_485 Isolation)

Usually the minimum measurable current value is 2% of the selected range. When selecting the current range (such as: 1A, 5A... 100A, 200A, etc. ), please try to select the range that is close to the measured current value. This can achieve the best measurement accuracy ^^ No matter whether the measured current is less than 10A, the meter must be connected to a shunt to measure the current regardless of whether the measured current is more than 10A! Otherwise it will burn the meter head ^^ When measuring current, only connect terminal GND and terminal I+ between the negative pole of the power supply and the negative pole of the load ^^ The power supply voltage of the meter must be 4.5 -28V. If it exceeds 28V, an independent power supply is required. Please connect according to the figure. The four points of the shunt cannot be changed at will
