FIRSTEC is developing primary components such as avionics & environmental control devices for KF-21, T-50, KUH, and LAH/LCH.

JWB Connector/VG95234 has the same structure as the threaded coupling JW5015A connector/MIL-DTL-5015, and is developed with the bayonnet method, which guarantees the stability of the coupling while being simple to combine and separate. It is used for military vehicles and ships such as tanks and armored vehicles because of its excellent moisture barrier and is resistant to vibration and shock. Based on these characteristics, it is widely supplied and applied to general industries.

The 100W High Power Amplifier is an L-band amplifier that delivers 100W output across two channels with a 60% duty cycle. It offers a gain of over 50 dB, with output flatness of 2 dB depending on the input signal level. The amplifier provides an ACLR performance of -20 dBc at maximum output. Equipped with an output-stage bandpass filter (BPF), it achieves excellent harmonic suppression of -70 dBc. Built-in monitoring functions include output signal and temperature monitoring.

Woori DS Co., Ltd. has developed firmware for a cooling and heating air conditioning system that performs all controls, fault diagnosis and communication for heating and cooling control and positive pressure control inside an armored vehicle, and developed an inverter control device capable of controlling communication with the armored vehicle body system and monitoring error situations. We are developing products based on the best technology and competitiveness to satisfy customer requirements for electrical equipment required for armored vehicles. In addition, we have developed an air conditioning system blower durability test device that can test the durability of air conditioning blowers, and we have secured test and evaluation technology for blower durability by checking blower errors and performing cycle management. By continuously securing innovative technologies in the defense industry, we are expanding our electronic device development business to deliver new value and impress customers with the highest quality and trust from product design, development, and mass production.

For electrical and electronic signal connections inside and outside the hermetic equipment, it reliably protects the device from extreme temperature/humidity changes, vibration and physical/chemical effects, and transmits signals and currents without loss. These connectors use special glass or ceramic as insulation and are used in furnaces, power breakers, submarines, gas control systems, transformer safety devices, etc. Key features of closed connectors: It completely blocks the interior from the outside environment to keep it vacuumed or pressurized. Durability: It works reliably in extreme environments (high temperature, low temperature, humidity, chemicals, etc.). Electrical performance: It delivers electrical signals or power without loss.
