Sumario:The High Voltage (HV) system of TileCal, the ATLAS central hadron calorimeter, is being upgraded for the High-Luminosity LHC, in the so called Phase II Upgrade. In the new configuration for the upgrade, the HV regulation boards are not located inside the detector anymore, they are deployed far from the radiation in a room where there is permanent access for maintenance. This option requires a large number of 100 m long HV cables but removes the requirement of radiation hard boards. HVremote regulation boards and the respective HV supplies boards have been developed and tested, as well as a crate to house the boards. Preliminary results of the HVremote boards performance are presented.
