Product Overview
The JLCK is an industrial-grade high-precision integrated control module engineered by Shijiazhuang Tonghe Electronics for global industrial power systems. Integrating dual-channel 3-phase 4-wire AC voltage acquisition, digital I/O, and equipment control, it serves as a core integrated unit for power monitoring and distribution systems.
Supporting 2-channel 3-phase 4-wire AC voltage sampling (0~300VAC phase voltage), it delivers ≤±1% measurement error within 170~265VAC, ensuring reliable data for system voltage monitoring.
Featuring an RS485 communication interface and 88~286VDC wide voltage supply, it seamlessly adapts to global industrial power architectures without additional modification, enabling easy installation and integration with upper-level monitoring systems.
Boasting excellent environmental resilience, it operates stably in indoor industrial environments (-10℃~+40℃, 95% RH @ 40℃±2℃, altitude ≤2000m), resisting conductive dust and corrosive gases.
Widely used in industrial power distribution, power monitoring equipment, rail transit power supply, and data center distribution.
