This test simulates the repetitive bending that materials and electrical connections may undergo during the normal use of an electrical device. The flexion can be performed at different angles, as specified by the standard's requirements, and the applied test load can be adjusted to represent various usage conditions. Electrical or PLC control allows for precise and repetitive test operation, and the results can be recorded for further evaluation as required by the IEC 60335-1 standard. The inclusion of a Power Load ensures comprehensive testing of the equipment's endurance and performance
