40mm L70 Compact Naval Gun We had designed the control systems and are manufacturing and supply to Doosan DST Co., Ltd.
This 40mm L70 Naval Gun is currently mounted on the PPC-class and FF-class frigate, and newly developed control systems will be mounted on PKG-class patrol boats.

Capacitor Bank
  > In order to solve the lack of durability of the high-speed rotary converter, we applied the ultra capacitor and reduced peak power consumption.

> By applying the ultra capacitor and charging uniform current reduced the peak power consumption.

> By using regenerative braking, the driving performance is enhanced according to the linear control.

> For reliability of power supply, we set up the CB test system.
Module Specifications
Capacitor Bank
