UChR-0.4-9-UHL4 — a variable frequency drive (VFD) manufactured by Toshelectroapparat (Uzbekistan), designed for industrial applications. It operates with a 380...480V AC, 3-phase power supply and is used to control asynchronous motors with a power rating of 9 kW. It is assumed to have an IP20 protection rating and is adapted for UHL4 climatic conditions (cold and temperate climates), but details about enclosure type, dimensions, weight, rated input/output current, and output current at 120% overload are not provided in the documentation. The device ensures efficiency, energy savings, and extended motor lifespan for controlling pumps, fans, and other medium-power industrial equipment. It is presumed to integrate with automated control systems (ACS) via the Modbus protocol.
