Intelligent electrical control systems are widely used in automated production lines, building automation, HVAC equipment, and small industrial control modules. Long-term continuous operation of such equipment can lead to issues like circuit leakage and power supply voltage distortion and fluctuations. Shift-based start-up and shutdown, as well as time-sharing operation, also require precise timing control, placing extremely high demands on the reliability and integration of control board-level protection and timing control chips. Rynova, relying on its self-developed Type B leakage protection chip, self-resetting over/under voltage monitoring chip, and multi-functional timing control IC, can provide various intelligent electrical control units with circuit leakage monitoring, abnormal power grid voltage protection, and multi-time-period timing start-up and shutdown solutions. These solutions are adaptable to complex industrial electromagnetic environments, ensuring the long-term stable and reliable operation of the electrical control system.
