Series DC Voltage Generators are used in series circuits to output a continuous high DC voltage at 50Hz or higher supply frequency to carry out DC withstand voltage insulation tests on electrical equipment and insulating materials (e.g. surge arresters, insulating oils). TPV can provide 150kV-750kV series DC voltage generators.

Special DC power supplies have a wide range of applications in modern industry. We provide high clean and large capacity variable frequency power supplies, high stability variable frequency power supplies, AC test reference power supplies, plasma high voltage DC power supplies, high voltage switching devices, portable high voltage DC power supplies and other equipment. TPV can provide a variety of customised DC high voltage power supplies for industrial applications:

● Irradiation DC power supplies: 10kV-50kV, 1A-20A
