Product Description
1. Product overview
MD880 belongs to the high-end frequency conversion speed regulation product technology platform of Inovance Technology. It is divided into two topological forms of single-machine transmission and multi-machine transmission. It is a system positioned for high-end transmission applications, high-performance speed and torque control, high reliability, and flexibility. Drive products with integration capability, convenient debugging and maintenance, and high power density coverage. Whether it is module structure, power density, response and accuracy, or the scope of application of the product, MD880 has set a new industry benchmark.

2. Application field

- Ship power Marine electric power drives main and auxiliary engine system equipment, installation ships and other cables
- Large frame stranding machine, coil stranding machine, copper and aluminum multi-motor large drawing machine, etc. Wind power converter, unit test bench, military equipment, power low-voltage control, oil and gas transmission, mine transmission and other equipment
3. Structure and characteristics
- Effectively reduce the current of the rectifier module and the brake module and simplify the device capacity.
- In applications such as lowering of potential energy load or winding and unwinding, the power generation and electric energy of each inverter module can be directly exchanged through the public DC bus.
- The rectifier module, inverter module, brake module and active rectifier filter module are all book-type module structures, with flexible selection, convenient cabinet assembly and quick maintenance. Book-type modules can be efficient.
- Utilize the depth of the cabinet, improve the utilization rate of the cabinet, reduce the number of cabinets, and save 30% to 60% of the floor space.
- The power module and optional parts can be assembled in the standard cabinet to ensure the high quality of the drive system as a whole. Two choices of components and cabinets are provided to meet the diverse needs of integrators and end users.

- Compared with single-point transmission, it saves a lot of incoming cables and power distribution protection equipment.
- Ensure the overall safety and control functions of the device and improve reliability.
