- Product Introduction
The Jinneng JKWF-32 is a dedicated control unit designed to manage and drive network-enabled composite switches. Engineered for industrial automation, it enables modular and intelligent reactive power compensation. With a built-in RS485 interface and Modbus-RTU protocol, the JKWF-32 ensures seamless integration with SCADA and PLC systems. Whether managing a single panel or a distributed network of up to 32 composite switches, this controller delivers the precision and reliability required for today's demanding industrial environments.
Products Feature
- 32-Channel Networked Control: Efficiently manages up to 32 composite switches, making it highly scalable for complex industrial compensation needs.
- Advanced Grid Analytics: A dedicated energy metering IC ensures high-precision measurement. The LCD screen displays real-time grid metrics, including Voltage (U), Current (I), Active/Reactive Power (P/Q), Power Factor (PF), Frequency, and Harmonics (THD-U/V).
- Smart Switch Diagnostics: Goes beyond basic control by actively monitoring switch health. Real-time diagnostics include contactor status, internal temperature, capacitor current harmonics, and capacitance value to prevent unexpected failures.
- Anti-Oscillation Switching Logic: Utilizes an MCU-based microelectronic circuit with multi-point sampling. Switching is triggered by reactive power (Q) measurements, effectively preventing grid oscillations caused by transient spikes.
- Robust & Reliable Design: Built to withstand harsh industrial environments. Features anti-interference microcontroller technology and a user-friendly HMI for intuitive configuration and operation.

FAQ
Q1: How does the JKWF-32 prevent capacitor switching transients?
A: The controller uses an advanced switching logic triggered by reactive power (Q) measurements rather than just power factor. Combined with multi-point sampling, this prevents the grid oscillations typically caused by capacitor switching transients.
Q2: Can I integrate this controller with our existing PLC system?
A: Yes. The JKWF-32 features a standard RS485 interface with the Modbus-RTU protocol, allowing for seamless, real-time data integration with most SCADA and PLC systems.
Q3: What kind of switch diagnostics does the LCD display?
A: The controller actively monitors the health of the connected composite switches. The LCD screen provides real-time feedback on contactor status, internal temperature, capacitor current harmonics, and capacitance value.
