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.
