Electronic components manufacturer TDK Corporation has released new EPCOS standard three-phase line reactors for frequency converters with input rectifier stages.
Designed for a rated voltage of 520 V AC and a short-circuit voltage of 5-6 percent—depending on the type—the new B86305L* series line reactors are suitable for suppressing electromagnetic interference caused by the frequency converters, the company said. The new line reactors cover a current range from 4 A to 230 A and feature constant inductance up to 1.5 times the rated current. Ideal applications include frequency converters for drives, pumps, elevators, air-conditioning and conveyer systems, as well as three-phase power supplies.
