We focus on new trends, follow technological developments around the world, constantly work on developing new products and improving existing ones. 

Modern technology

ELKO EP is a world leader in the development and production of electronic relays used in domestic and industrial electrical installations. We offer more than 150 types of relays made of high quality parts and components with over 5 years warranty. Our systems offer the best solutions for intelligent automation, making sure that the electronic components and systems you already use every day work together seamlessly. By integrating everything - lighting, music, video, climate control, security - we create personalized experiences that enhance your life and work with added comfort, savings, convenience and peace of mind.

INELS home automation systems provide maximum convenience and flexibility, offering cable (BUS) and wireless (RF) control of lighting, heating, air conditioning, multimedia devices, security cameras, detectors and many other devices. Wireless control is a solution for home automation (RF wireless electrical installation) for existing homes, and cable (BUS smart home installation) - for new construction.

A building management system (BMS) is a management system that can be used to monitor and control the mechanical, electrical and electromechanical services in any building. Such services may include power, heating, ventilation, air conditioning, physical access control, pumping stations, elevators and lights. It is a system that can think for itself, a system that can save you time, energy and money.

No repairs need to be made to modernize a hotel room, thanks to our iNELS Control wireless electrical installations. You can wirelessly perform the reconstruction incredibly fast and clean - without the need for repairs such as cutting, gouging, demolition of walls. You can connect devices without additional wiring.

  • GRMS system: For a new hotel to be smart is not only a standard but also a necessity. This system is designed for newly built hotel complexes, taking into account every detail and requirement for automation. The possibilities for communication with other systems are almost limitless and the goal is to unite everyone in one management interface.
  • Upgrading HRESK: Thanks to the wireless communication of the devices (sensors, drives and controllers), the modernization of an existing hotel room can be done in a short time and without disturbing the walls or repair work. The miniature controllers can be installed almost anywhere and anywhere and without wiring.

And with the installation of a restaurant automation system, you take control of electricity consumers and optimize costs, while improving comfort and making the atmosphere more pleasant.

We have more than 23 years of experience in the field of modular electronic devices - from smart relays to intelligent electrical installations that can connect all appliances in your household. Our smart solutions can also be used in hotels, office buildings, factories and industrial halls, medical centers, malls, shops and more.

ELKO EP Bulgaria also offers the newly developed iNELS Air system. It was created to serve the dynamically developing network of "IoT network" (Internet of things). The product range consists of sensors and relays communicating with each other via NB-IoT, Sigfox and LoRa networks.

Quality control

The quality of our production depends on all the components and therefore when selecting our suppliers we have to pay more attention to the quality of the material supplied. To prevent possible errors we perform testing at different levels and intermediate stages of the product production phases.

Development tests - tests of pilot components and prototypes

Tests performed on the newly developed products are tested for every possibility of normal use. We make sure that all tests meet stricter parameters than the specify conditions for certification

Manufacturing process control
  • Product audit - randomly selected products are subjected to full, well-defined tests
  • Production documentation in electronic form only
  • Management of documentation with IS ABRA - minimizing "human" errors
  • Increased control of "zero" series
Long-term stress tests
  • Tests, which measure product performance at higher loads than the stated standards
  • Burst / Surge - EMC - electromagnetic compatibility
  • Long-term tests for measuring product performance after warranty expiration
  • All tests are evaluated and stored in electronic form
Manager EMS (ISO 14001)
  • Compliance and monitoring processes
  • Corrective measures, surveillance audits

The basis of our production is a modern fully automatic production line for SMD components.
