The RL/RC Load Bank is a modular composite load testing equipment, divided into RL resistive-inductive type and RC resistive-capacitive type, which can be combined as required to meet different testing needs. The RL resistive-inductive load can simulate the inductive load working conditions of industrial motors, compressors, transformers and other equipment; the RC resistive-capacitive load can simulate the capacitive load working conditions of precision electronic equipment, communication power supplies and capacitive power distribution systems. With streamlined structure and flexible parameter adjustment, the equipment solves the limitation of single load testing. It is suitable for special performance testing, aging verification and working condition simulation of small and medium-sized power equipment, industrial control equipment and communication power supply systems, with high cost performance and wide application scenarios.
