Manufacture and delivery of main-part reflectors used in unmanned aerial vehicles.

Developed in 2002 as a single-soldier, short-range, anti-tank weapon system, we continue to work with soldiers to provide the weaponry needed to succeed. Backed by nearly two decades of experience, the resurgence of the tank in battle validates our expertise in this field. It’s the same old story – and David still beats Goliath.

To guarantee maximum safety and reliability, our DA 30 features a brushless motor and a contactless wear-free position sensor. This means maximum service life with the greatest‐possible power delivery and its design prevents electromagnetic emissions (EMI) caused by brush sparking. The housing made of saltwater‐resistant aluminum is HART‐coat treated, meets the IP‐67 standard for water and dust sealing and provides an integrated Sub‐D connector (MIL spec. circular connector or cable gland on request). Brackets integrated in the housing for horizontal and vertical assembly. 8‐fold, ball‐bearing supported, steel gear train, drive shaft with ANSI multi‐tooth. The DA 30 series can be equipped with a standard PWM input (Pulse Width Modulation) that has two different interfaces: a differential, galvanic isolated interface (Opto‐Coupler) and a single‐ended interface with CMOS levels that is also used to program the servo parameters. It includes analog position feedback to detect the drive shaft position. A differential RS‐422 PWM interface can be chosen instead of the opto‐coupled interface. The DA 30 with digital serial command interface (RS‐485) receives its commands via a CRC secured protocol. It can return not only the shaft position in digital format, but also several diagnostic data such as the level of the supply voltage, current consumption and the temperature of the motor and electronics in digital form (optionally also the humidity within the actuator case). These kind of diagnostic capabilities help to determine the health state of the actuators before, during and after deployment.

STX Engine produces medium speed engine driven power generation equipment that can satisfy customers 100% by ideally combining medium speed engines, which have been collectively produced at our Changwon factory since obtaining licenses from the mid 1970's from MAN ENERGY SOLUTIONS in Germany and NIIGATA POWER SYSTEM in Japan, with a power generation system designed with rich experience in the area of system engineering. By installing diesel engine power generation equipment in locations across Korea and overseas, such as on islands, remote areas, resorts, etc., where no public power supply is available, as well as industrial complexes and hospitals which require good source of power, and factories receiving expensive public power supply, etc., our customers can confirm the investment effect within a short period of time after experiencing the power supply we make available to them, as well as low installation and operation costs and maximized availability of the equipment.

Sungjin Techwin’s control grips are designed to provide pilots with intuitive and precise control in critical missions. Engineered with ergonomic layouts, high-reliability switches, and NVIS-compatible backlighting, our grips are fully customizable to meet diverse cockpit requirements. Qualified under MIL-STD and DO-160 standards, they ensure durability and safety in extreme operational environments. With proven applications across programs such as KF-21, KUH, LAH, and the Calidus B-250, our control grips demonstrate world-class performance and trusted reliability for next-generation aircraft.

FIRSTEC is providing key components of guided weapon, such as Actuation System, Gudiance Control Unit, Fire Control Unit, and wire harness, to complete systems such as Hyunmoo, Raybolt(Hyungung), Bigung(Poniard), M-SAM II(Cheongung II), L-SAM etc. applying them to each business.

This system product is a product that directly supplies and heats lubricant oil for smooth operation of the main engine cylinder’s metallic and mechanical movement. Lubricator, a product that supplies lubrication directly to the main engine cylinder liner, can control injection timing and consumption using an electronic control method that responds to the movement of the main engine piston. The alpha lubricator system is based on an algorithm controlling the cylinder oil dosage proportionally to the sulphur content in the fuel and, fuel consumption on particular load of engine. Minimum cylinder oil dosage is required to provide an adequate oil film and detergency properties. Everllence and WIN GD engines are currently applying the second generation Lubricator type, the Everllence type is Mk-I and the WIN GD type is Mk-ε (Epsilon).
