In GSI for SIS100 accelerator about 530 HTS Local Current Leads 250 A must be produced for superconducting corrector magnets. To provide a high voltage electrical insulation, the top warm terminals must be kept at a temperature of 25 °C, using screwed cartridge heaters. Known industrial cartridge heaters don’t meet insulation specification at 1100 V. All tested temperature regulators on the free market failed during the tests at GSI or/and produced significant electrical noise. With the specifications from GSI we developed and manufactured 8 channel temperature regulators for the SIS100 HTS current leads which were successfully tested and with low noise. GSI and ILK also developed reliable cartridge heater with high voltage insulation and imbedded temperature sensor. Design issues and test data are presented in this paper.
