Core technical parameters

Measurement system: Adopting a microprocessor system, it can be applied to balance three-phase networks or single-phase networks, providing adaptability for different power system architectures.

Working voltage range: Supports wide voltage input of 100... 240V AC, can adapt to various common grid voltage environments, and can operate stably in industrial, commercial, and civilian scenarios.

Frequency range: It can operate normally at frequencies of 50Hz or 60Hz, meeting the frequency standards of power grids in different regions.

Current input: With 1A or 5A (rms) current input options, it can be flexibly configured according to the actual current size of the power system. The input impedance is less than 0.1 ohms, ensuring accurate acquisition of current signals.

Current carrying capacity: The maximum continuous current can reach 1.5A, and the maximum peak current is 5A, which can cope with possible instantaneous current surges in the power system.

Maximum voltage: capable of withstanding voltages up to 440V AC, suitable for power system applications of different voltage levels.

Terminal current rating: The continuous current rating of terminal A is 16A, ensuring the reliability of the equipment when connected to external circuits.

Power consumption: The maximum power consumption is 15VA, which effectively controls energy consumption while ensuring high-performance operation of the equipment.

Version: The current version is v3.5, and continuous version iterations ensure the optimization of product performance and the improvement of functionality.

Output quantity: The RVC6 version has 6 outputs, which can be used to connect and control multiple compensation capacitor banks, achieving fine adjustment of power factor.

Functional characteristics

Power factor automatic control: It can automatically detect the power factor situation in the power grid, and dynamically adjust the input and disconnection of compensation capacitors based on actual measurement results, ensuring that the power factor is always maintained within an appropriate range, effectively improving the power quality and efficiency of the power system.

Key parameter measurement and display: It can accurately measure key parameters such as voltage, current, power factor, total harmonic distortion voltage (THDV), and total harmonic distortion current (THDI), and present them intuitively on the equipment display screen, providing comprehensive power system operation data for operation and maintenance personnel.

Programmable switch sequence: Supports fully programmable switch sequence settings, allowing users to flexibly customize the switching sequence of capacitors according to the actual needs and characteristics of the power system, in order to achieve the best compensation effect and equipment operation stability.

Automatic setting function: It has a complete automatic setting function, including automatic recognition of starting current - C/k, automatic determination of switch sequence type, automatic detection of phase shift, automatic recognition of special connections, etc., greatly simplifying the debugging and initial configuration process of the equipment and reducing the threshold for use.

Efficient switching strategy: Combining multiple efficient switching strategies such as integral, direct, and cyclic switching, it can accurately control the power factor (cos j) even in complex working conditions with rapidly changing loads; At the same time, this strategy can significantly reduce the number of switch operations, effectively extend the service life of capacitors and contactors, and reduce equipment maintenance costs.

Strong environmental adaptability: The maximum rated ambient temperature can reach 70 ° C, and it can operate stably in high temperature environments, suitable for various harsh working environments; And the equipment is not affected by harmonics, and can still accurately control power factor in power systems with harmonic interference.

Multiple protection mechanisms: equipped with overvoltage/undervoltage protection function, automatically taking protective measures when the grid voltage exceeds the normal range to avoid equipment damage due to abnormal voltage; At the same time, there are corresponding protection mechanisms for harmonic distortion (THDV) to ensure the safe operation of equipment in complex power environments. In addition, when all outputs fail to reach the target power factor within 6 minutes after being turned on, the internal temperature of the device exceeds 85 ° C, the overvoltage/undervoltage limit is reached, or the THDV exceeds the limit, and other abnormal situations occur, the alarm contact will automatically open to promptly remind the operation and maintenance personnel to troubleshoot and handle the problem.
