Overview
The capacitive liquid display compensation control device has an RS485 communication interface, and the sampled voltage, current, frequency, active power, reactive power, harmonic content, power factor, and temperature can be transmitted to other external devices through the communication interface. The product has functions such as overvoltage, undervoltage, undercurrent lockout, phase failure, over distortion, and temperature protection.
Product Details
Capacitive liquid display compensation control deviceFunction:
This product has an RS485 communication interface, and the sampled voltage, current, frequency, active power, reactive power, harmonic content, power factor, and temperature can be transmitted to other external devices through the communication interface. The product has functions such as overvoltage, undervoltage, undercurrent lockout, phase failure, over distortion, and temperature protection.
Application scope:
Suitable for reactive power compensation in low-voltage distribution systems, it can be used in conjunction with static capacitive screens (cabinets) with voltage levels below 400V or 660V.
Ordering Example:
Specific model: ARC-6/J-KT
Technical requirements: Input three-phase voltage AC220V; Input current AC5A; Sequential cutting method; Compensation method: three-phase co compensation; 6 control routes for switching; 6-way switch input; Temperature detection inside the cabinet.
Communication protocol: RS485 interface Modbus/RTU protocol
Auxiliary power supply: AC220V
Capacitive liquid display compensation control devicefunction
Real time monitoring and display of liquid level
Using high-precision sensors (such as immersion level transmitters), physical quantities are converted into electrical signals (such as 4-20mA current) by measuring liquid pressure or liquid level height, and the current liquid level value is displayed in real time.
The display methods include LED digital display, illuminated column simulation of liquid level rise and fall, and intuitive reflection of liquid level changes.
Automatic compensation control
According to the preset liquid level threshold, automatically control equipment such as water pumps and solenoid valves to achieve constant liquid level control and automatic drainage/replenishment functions.
Support full level alarm and low level alarm to prevent overflow or dry burning, ensuring system safety.
Communication and extension functions
Standard RS485 communication interface, supporting Modbus RTU and other protocols, can be networked with the upper computer system to achieve remote monitoring and data exchange.
Some models provide relay output, switch input, and support local or remote control (such as "remote signaling" and "remote control" functions).
