Representative Products of Yousung
The DC ground processing system is a leakage current detection device with alarm output function per each channel and fault record function in cases where a ground fault occurs, as it is always monitoring the leakage current in DC power supply line (P/ N phase) at the power plant or the substation through CT with communication. Furthermore, it features digital protection relay based on real-time operation and measurement method by removing noise interference. It is possible to select fault detection method on each channel and to extend and select channels.
Solid control relay is a GIS (Gas Insulated Switchgear) control device, which is the fast programmable logic controller in LCP (Local Control Panel) function of 25.8kV GIS. This hybrid system is combined with sealed relay and power semiconductor devices to replace the existing relays used in gas-insulated switchgear. It features interlock logic function based on PLC (Programmable Logic Controller), remote control function, real-time monitoring function, convenient program upload, connector lock type and energy saving.
Interlock module device is the fast programmable logic controller of 154/345kV Interlock Panel controller. This hybrid system is combined with sealed relay and power semiconductor devices. It features an interlock logic function based on PLC, remote control function, constant monitoring system, connector lock type, convenient user interface and event record system.

Connex is operating the quality management system for customer satisfaction and has acquired several certifi cations such as ISO9001, Venture Business, Inno-Biz and the company’s research center. It also has product performance certifi cations related to UL, TUV, CE, FCC, RoHS and KC.
Power maximizer maximizes PV system efficiency at the lowest cost. It increases energy efficiency by recapturing up to 50% of lost energy in shade conditions.
Quick solar supplies power fast to people in disaster zone and remote area. It features fast power supply with easy and fast installation and full batt ery charging. It carries excellent quality with certifi ed components. It is a readily made product without any errors in installation. It has suffi cient batt ery storage that lasts for three days without sunshine.
The whole slow juicer Chef CS600 is patented for low-speed extraction which makes this press juicer slowly press and squeeze ingredients rather than grind them. The model provides you more juice with improved screws, a linear drum and fi ne sieve, while with increased pulp amount and reduced staying amount in the air.
The ICS system is able to eff ectively eliminate all multipath signals including direct feedback from the coverage antenna, indirect feedback from predictable obstacles and can now even cancel indirect feedback from unpredictable obstacles despite changes in feedback signal timing and amplitude.
The accelerating global demand for multi-band mobile services requires reliable and high
A powerful magnet realizes hands-free use. A 360° rotation hook comes in handy.
t to develop high-quality technology and products in order to secure a dominant position in the domestic market and strong competitiveness in the international market. High technology and good quality enabled Solarzen to export its products to more than ten countries such as the USA, Japan, Russia, Thailand and the Philippines.
Fixtures (Fix-S, Fix-I and Fix-E) feature strong initial fi xation power because of the special design technology of the screw parts. Each screw thread makes moves independent depending on its size and role and has excellent initial fi xation power, so it is possible to make implants more stable. It can make perfect bone incorporation in such a short time through an SLA-Type surface treatment method (RA: 2.7). A&B Implant is a high-tech system designed to be compatible with international implant system.
