The SITOP PSE200U 3 A NEC CLASS 2 selectivity module is a four-channel device designed for selective monitoring of 24 V DC power supplies. It safeguards against overloads and short circuits in individual branches of a 24 V DC power supply system. This module ensures that only the affected circuit is disconnected, while the remaining circuits continue to operate without interruption. Each of the four channels provides an output of 24 V/3A, adhering to NEC Class 2 standards. The tripping current for each channel is adjustable within a range of 0.5 to 3 A, allowing for customization based on the specific requirements of the connected devices. Integrated status messages for each output channel provide real-time feedback on the operational status of each circuit. This enables quick identification and resolution of any issues. The SITOP PSE200U enhances system availability and reduces downtime by preventing widespread failures due to localized faults. It is an ideal solution for applications requiring high reliability and selective fault isolation in 24 V DC power distribution systems. Its compact design and easy installation make it suitable for a wide range of industrial applications.
