Product Overview
The XHBP series variable frequency resonant test device is primarily composed of a variable frequency control power supply, an excitation transformer, a reactor and a capacitive voltage divider. A rectifier silicon stack can be connected after the capacitive voltage divider to conduct DC withstand voltage tests on equipment.
