Four-quadrant Inverter

CRH7012 Series



Product Introduction


CRH7012 series power supply with integrated control of rectifier and inverter adopts four-quadrant control technology, which can realize battery charging and discharging control through rectification, and provide power supply for external through inverter control, and it can meet the battery charging and discharging and inverter power supply requirements in hybrid power systems such as tire cranes and gantry machines.



Product Characteristics


1)Adopting modularization technology, the product structure is compact, small in size, convenient in plugging and unplugging, and easy in maintenance.

2)With expand-ability, it is convenient to increase the capacity of RTG power supply equipment.

3)It has the protection functions of phase failure, under-voltage, over-voltage, over-current, over-temperature, short-circuit, overload, inverse power, misoperation and so on.

(4) Compatible with a variety of communication protocols, it can conveniently communicate with PLC and upload various operation status parameters to the remote computer, which is convenient for data management and monitoring in the port.

(5) It is equipped with convenient man-machine operation interface, which is convenient for users to carry out local operation and parameter monitoring.

6)Can carry out constant voltage and current limitation charging control for the battery in the hybrid power system.

(7) Invert DC power into constant voltage and frequency AC power to provide power supply for secondary equipment.

(8) The rectifier link and inverter link adopt the same topology and hardware structure design, and can replace each other.
