The NBHD series marine inverters produced by our company are designed with 24V DC power as input, through high-frequency power conversion, and using a new MCU-controlled dual feedback loop structure. AC output 220V/50Hz pure sine wave, with excellent dynamic response characteristics. The first static microprocessor control technology is adopted, so it has good dynamic characteristics and working reliability, and has the advantages of small size, light weight, no noise, maintenance-free, high efficiency, and easy operation.
Work Principle

The NBHD-inverter is designed for the specific requirements of the inverter power supply used by ships. It takes 24V DC power supply as input, through high-frequency power conversion, and uses a new MCU control double feedback loop structure design made. AC output 220V/50Hz pure sine wave, with excellent dynamic response characteristics. It can be seen from the figure that the NBHD inverter first passes the DC input through the input filter circuit, and then through the DC/DC conversion, the DC that changes in the range of 20 ~ 30V is raised to a DC high voltage, and then passes through the DC/DC conversion. - A half-bridge inverter circuit, which converts the DC high voltage into an AC output voltage of 220V/50Hz, and finally provides a sine wave voltage for the load through the output filter circuit. NBHD inverter and NBHD-6, NBHD-8, NBHD-10, NBHD-12. NBHD-15. NBHD-20, NBHD-30 seven specifications. The inverter adopts high frequency power conversion technology, Small size, high power density, stable and reliable operation, can be widely used in various types of ships AC power supply.
Primary PurposeFunction
It is suitable for various offshore platforms and ships, and provides inverter power for related equipment on board.

Primary PurposeFunction
ZDZ series DC power conversion box is used as DC power supply equipment on ships. After being equipped with a battery, it can supply power to DC loads without interruption.
The main working principle of ZDZ series DC power conversion box: when AC power is supplied, the three-phase 380V voltage is converted to the corresponding low voltage by the three-phase AC constant voltage transformer, and then after three-phase full-wave rectification and filtering, a stable DC output voltage is obtained, and the DC load power supply, when AC power is lost, it can automatically and uninterruptedly switch to the battery power supply. The device also has over-voltage, over-current, load-break protection functions. The charging and discharging times of the battery are effectively reduced, the service life of the battery is improved, and the uninterrupted power consumption requirements of the DC load are also met.
