Based on technology accumulated over 60 years, Dong-A Electric Device Co. has maintained the leading position in the domestic circuit breaker and contactor fi eld.
With ISO 9001 international certifi cation, the company has acquired foreign standards such as CE and TUV.
Operating its own research and development institute, it has ceaselessly released innovative products to bett er meet the changing demand from customers both at home and abroad.

Competitive Export Items to Expand Overseas Markets
The maker’s currently popular export items include molded case circuit breakers (MCCB), earth leakage circuit breakers (ELCB), magnetic contactors (MC) and magqnetic switches (MS).

The fi rm’s zero current transformer (ZCT)-embedded MCCBs and twin 4P type ELCBs are the world’s fi rst in its kind. These items have been designated as “New Excellent Products (NEP)” by the Public Procurement Service of Korea. Their cartridge-type structure ensures bett er user convenience. MCCBs, ELCBs, ZCT-embedded MCCBs come in the same sizes. They need minimized att achment space thanks to their compact sizes and light weight.
All-in-one type MCCBs bring about sharply reduced material and personnel costs.
Hot-selling DB and DBE Series models in the MCCB and ELCB sector are economic breakers which eff ectively protects from damages from a fi re danger and equipment damages caused by overload or short. Both complete electric and thermal electric types present excellent performance characteristics. With their standardized their sizes, they have great compatibility with other type products and accessories.

Meeting international quality standards, MCs and MSs from the maker feature simple wiring, stable movement and long mechanical/electronic life.
Pouring huge investments into research and development, the manufacture has been designated as “INNO-BIZ” company by Korean government. “We will fulfi ll our role and missions in this fi eld in Korea by constantly developing new technologies and focusing on transparent administration,” says company president Lee Man-woo.

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.

Macrogen’s global genome network has been established mainly in Europe, Japan, and Central and South America, with which Macrogen has been discussing large joint genome research programs.
The company’s myPETGENE utilizes genetic testing services for preventive treatment of diseases, preventing loss and abandonment by owners, in order to promote both the well-being of pets and to establish a healthy culture regarding animal companions. Certifi cation of chromosomal identifi cation, including genetic disease markers, is becoming a standardized cultural procedure in adopting healthy animal companions. myPETGENE promises to regard your animal companions as family and will strive to establish a healthy pet culture by providing high-quality services through constant research and development.
DNA profi ling is a testing method which extracts DNA from a sample obtained from a pet, and analyzes the genetic patt ern. Through DNA profi ling, the company compares and analyzes genome sequence to determine whether the DNA is from the same species, or keeps the analysis results for future use. myPETGENE off ers analysis result based on ISAG (International Society for Animal Genetics) standard.
First step into myPETGENE’s blood relationship is to express genotype of pets. Being genetically inherited DNA forms in pairs – inherited by each side of parents. Blood relationship can be scientifi cally proven by comparing the DNA pairs.
A powerful magnet realizes hands-free use. A 360° rotation hook comes in handy
Model No. SWL-320R1_(10W) is a fully waterproof and dustproof (IP67) industrial LED work light. The product is rechargeable. LG Innotek’s LEDs and LG Chemical’s lithium-ion batt eries went into this product. An over-charging/ discharging protection circuit was installed in the product
The accelerating global demand for multi-band mobile services requires reliable and high performance network equipment that supports various technologies such as WCDMA, LTE, as well as allowing each mobile operator to make increasingly effi cient use of their budget.
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.
Connex Electronics has been mainly supplying automotive connectors since its foundation in 2001. It strives to satisfy customers’ requirements with its accumulated experience and technology in the fi eld of automotive electrical component fi elds. Connex will do its best in the coming years to ensure continued growth of the Korean automotive industry.
Power maximizer maximizes PV system effi ciency at the lowest cost.
Because of overload, moisture, momentary inrush current caused by load, and lightning, internal parts of such winding type generators can be damaged, which stops the operation of the generator. Suntech has solved these problems by developing a high-effi ciency generator and using a permanent magnet rotor of 3~2000kw. In designing the rotor for the permanent magnet generator, Suntech used a fi nite element method. It could improve waveforms, eff ectively arrange a permanent magnet, design an optimum rotor and insert a magnet. By doing this, it minimized leakage fl ux and improved effi ciency.
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.
