Low-voltage Integrated Devices
Integrated Devices for Controlling Electrical Machines and Appliances
Low-voltage integrated devices (panels, cabinets, enclosures), abbreviated as LVID, are designed to receive and distribute electrical energy in networks with voltages up to 480V, frequency 50Hz, with a solidly grounded neutral. They enable remote, automated, and manual control, monitoring, signaling, and protection of equipment from short circuits and overloads, ensuring human safety from electric shocks. A pump control panel is a system used for automated pump management, typically employed in fluid transfer applications such as water, fuels, chemicals, and similar substances. These devices find widespread use in water supply, heating, cooling, industrial processes, and more. Our integrated devices are fully serviceable and reliable, comprising individual components like switches, contactors, relays, lamps, buttons, and others. To maintain competitive pricing and ensure dependable quality, we partner with renowned brands including Siemens for controllers and HMI panels, Schrack Technik for circuit breakers, contactors, and thermal relays, ABB for circuit breakers, contactors, and thermal relays, LS (Korea) for circuit breakers, motor circuit protectors, contactors, and residual current devices, F&F (Poland) for relays and controllers, and Kinco for controllers, HMI panels, and frequency inverters. We also provide installation and commissioning services. Our devices come with a standard 2-year warranty. In our manufacturing processes, we adhere to the guidelines of ргБДС EN IEC 61439-1:2021/:2024. We continually refine our assembly processes to reduce turnaround times.
