Product Introduction

Drawing on proven power electronics and platform-based control technologies, Chengrui Power Technology has developed a series of cascaded shore power inverter power supplies with maximum capacities of 1250 kVA, 1600 kVA, 2000 kVA, 3000 kVA, 4000 kVA and 5000 kVA. These units are capable of operating in parallel—with two or more units connected in series—across all capacity levels, thereby meeting users’ requirements for high-voltage, high-capacity power supply on board vessels.



Product Features


(1) The output transformer is treated with vacuum impregnated insulating varnish in real gas and sprayed with high temperature protective varnish, which has high insulation level and protection capability.

(2) It has multiple protection devices to ensure system to be secure and in a normal operation.

(3) It has an input metering cabinet unit, which measures and displays input voltage, current, power, power factor, and electrical energy.

(4) With multi-output distribution metering unit, power distribution to the user load, distribution unit grid voltage abnormality, DC over-under-voltage, short-circuit, over-current, ground fault, communication failure, overload, overheating and other multiple protection devices.

(5) It can measure and display the voltage, current, power, power factor and electric energy of each electric outlet.

(6) According to the user's on-site requirements, each distribution output is equipped with a special cable connection interface, which is convenient for quick connection.

7) Wired or wireless data transmission service is available to collect system data and monitor system operation via computer.
