Power controller Granch SBTC-PS - is developed for intrinsically safe power supply of SBGPS Master base stations and other technical means

 

 

 

 

Сertificate of conformity TR CU № RU C-RU.AA87.B.00456.

The controller is available in the following versions:

  • Granch SBTC-PS1 – with one power supply unit;
  • Granch SBTC-PS2 – with two power supplies.

The power supply generates intrinsically safe voltages for powering external equipment.
