This device is suitable for48VThe110VThe220VThe measurement of DC system voltage and current can measure the ambient temperature on site, and the measured values of voltage, current, and temperature can be obtained throughRS485Bus transmission, usingmodbusCommunication protocol, power supply voltage85~264VAC，100~370VDCor36~75VDCOptional.

The device is stable and reliable, and the power supply and voltage measurement circuit have anti reverse connection, overvoltage, and overcurrent protection; External opening and closing Hall sensor can measure positive and negative bidirectional currents;RS485support115200Baud rate, can be connected in parallel256A node with lightning protection and other protective measures. Customized services are supported for special application scenarios.

The device has a small volume, light weight, and uses a non-metallic shell to further reduce potential safety hazards during on-site use. It is an effective solution for high reliability and precision requirements of on-site voltage, current, and temperature detection in DC systems.

2.1wiring

The device has a single-sided outgoing line, and the corresponding names of the wiring terminals are shown on the labels in the following figure:

Power supplyAC/DC”: Connect power supply, AC/DC dual-use, optional85~264VAC，100~370VDCor36~75VDC.

'Empty':thatThe terminal is an empty terminal with no electrical connection inside.

Voltage Test ": The input terminal of the DC voltage to be tested.

Current measurement:4Connect the terminal to the corresponding terminal on the external switchable DC Hall current sensor. The dimensions and terminal definitions of the switchable DC Hall current sensor are shown in the following figure“+12V”Connecting devices“12V”, sensors“-12V”Connecting devices“-12V”The sensor's“OUT”Connecting devices“IN”The sensor's“0V”Connecting devices“0V”. When the direction of current flow is consistent with the arrow on the sensor, the measurement result is positive, otherwise it is negative.

“RS485”: Connect485Bus, among which“G”For485Signal ground rather than earth, determine whether to connect based on on-site usage.

Power indicator light: Always on when powered on.

Communication indicator light: flashes during communication.

Temperature measurement ": a temperature sensor used to measure the ambient temperature.
