RENLE RNB8 SERIES

Features:

The modular design of the book-type saves cabinet space, which is suitable for the compact installation of multiple units side by side, and the cabinet space utilization rate is high.

Energy-saving and high-efficiency common and DC bus connection, automatic distribution of electric power consumption and braking power generation energy, saving braking energy consumption and high power utilization.

The centralized power supply with low power grid pollution reduces the harmonic pollution and EMI interference on the power grid on the input side of the inverter.

The communication technology adopts PROFIBUS-DP communication to realize long-distance high-speed communication between the inverter and the inverter, and between the inverter and the host computer controller system.

Excellent multi-machine synchronous control performanceMulti-machine synchronous control has the excellent performance of fast response, high precision and strong stability, and can realize the dynamic synchronous operation of multiple motors with load.

Powerful, flexible and easy-to-use modular unit design, power expansion is convenient and flexible. The product has I/O and communication interfaces, and other expansion interfaces are also reserved.
