Multi circuit DC meterIt is an intelligent instrument that can simultaneously monitor electrical parameters of multiple DC circuits. Its core function is to optimize the operation and management of DC systems through centralized and high-precision data acquisition and analysis.

1、 The function of a multi circuit DC meter

Multi loop synchronous monitoring

Independent channel design: Each circuit is equipped with independent current sensors (such as Hall sensors) and voltage sampling circuits, which can simultaneously measure voltage, current, power and other parameters of 4-32 DC circuits.

Parameter coverage: In addition to basic parameters, some models can also monitor circuit status (such as on-off, overload), accumulated energy, harmonic content (for high-frequency switching power supply systems), etc.

High precision data collection

Sampling frequency: Usually supports high-speed sampling from 1kHz to 10kHz, which can capture transient current changes (such as start-up surges and short circuit faults).

Accuracy level: The current measurement accuracy reaches ± 0.1% FS, and the voltage accuracy is ± 0.05% FS, meeting the strict requirements of DC systems for data accuracy.

Real time data analysis and alerts

Threshold setting: Users can customize the upper and lower limits of voltage and current overload thresholds. When the parameters exceed them, an audible and visual alarm or remote notification will be triggered immediately.

Fault location: By comparing the parameters of each circuit, quickly identify abnormal circuits (such as a sudden drop in current in a certain circuit, which may be an open circuit fault).

2、 Application scenarios

DC power supply system for data center

Scenario requirement: The data center adopts a -48V DC power supply architecture and needs to simultaneously monitor the power consumption of dozens of circuits such as server cabinets, battery packs, UPS, etc.

Function of multi circuit meter:

Real time monitoring of the current in each cabinet to avoid power supply failures caused by unbalanced loads.

Calculate the charging and discharging energy of battery packs and optimize battery management strategies.

Upload data to the Power Environment Monitoring System (DCIM) through communication interfaces such as RS485 and Modbus TCP to achieve centralized management.

New energy vehicle charging station

Scenario requirement: The DC fast charging station needs to manage multiple charging modules simultaneously (such as each module outputting 60kW) and monitor the connection status between the charging gun and the vehicle.

Function of multi circuit meter:

Monitor the output current and voltage of each charging module to ensure safe and stable charging process.

Statistics of charging energy, supporting time-sharing billing function.

Through CAN bus or Ethernet linkage with the charging station control system, automatic shutdown protection is achieved for faults.

Industrial automation production line

Scenario requirement: Automation equipment (such as robots, CNC machines) are driven by DC motors and require independent monitoring of the energy consumption and operating status of each motor.

Function of multi circuit meter:

Real time display of the current of each motor to assist in determining load changes (such as mechanical jamming causing a surge in current).

Record the start stop time of the equipment and analyze production efficiency.

Integrate with PLC system to achieve visualization of energy consumption data and energy-saving optimization.

Photovoltaic energy storage system

Scenario requirement: The energy storage power station needs to monitor the charging and discharging status of multiple DC circuits such as the battery stack, PCS (energy storage converter), and load.

Function of multi circuit meter:

Monitor the current of each branch of the battery stack to avoid local overcharging/overdischarging.

Calculate the output electrical energy of PCS and evaluate the efficiency of the energy storage system.

Upload data to the cloud platform through 4G/5G modules, supporting remote operation and maintenance.

IIIMulti circuit DC meterTechnological advantages

Space and cost optimization

The traditional solution requires a single circuit instrument to be configured for each circuit, while multi circuit meters can reduce installation space and cable costs by more than 80% through integrated design.

Data consistency assurance

All loop data is collected synchronously to avoid analysis errors caused by sampling time differences between multiple instruments and improve the accuracy of fault diagnosis.

Scalability and compatibility

Supports multiple communication protocols such as Modbus, Profinet, IEC61850, etc., and can seamlessly integrate into existing monitoring systems.

Some models offer analog output (4-20mA) or relay output, supporting linkage control with third-party devices.

4、 Key selection points

Matching of circuit quantity: Select the number of channels according to actual needs (such as 8 circuits, 16 circuits), and reserve 20% margin to cope with future expansion.

Measurement range: The current measurement range should cover the maximum current of the circuit (such as 0-100A), and the voltage range should match the system voltage (such as 0-1000V).

Protection level: IP65 or above protection level should be selected for industrial scenarios to ensure dust and water resistance performance.

Certification standards: Priority should be given to products that have passed international certifications such as CE, UL, IEC, etc., to ensure safety and compliance.
