Taidacent Modbus RTU Power Monitor Energy Meter with RS485 TTL Isolated 100V 5A 10A 50A 100A DC Voltage Current Meter with Dual LCD Display (100V100A Modbus Protocol 485 Isolation)

Features

• 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
