Static Automatic Bus Transfer SABT

Static Automatic Bus Transfer (SABT) Systems are designed to transfer the alternating current supply (AC), between independent single-phase, or three-phase AC power sources. SABTs provide an automatic switching between AC sources, to ensure power to critical loads connected to their output.

The basic applications of SABT are automatic systems for the energy industry, power supply systems for communication centers, computer and telecommunications centers, operating rooms, intensive care units (ICU), security systems, as well as other equipment that is highly sensitive to supply interruptions.

Its high overload capacity and fuses connected in series with the SCRs allow a fast and safe bus transfer. The system incorporates overvoltage suppressors to prevent the SCR devices damage.

The SABT unit is fitted with switches that allow selecting the operating mode: MANUAL or AUTO. The manual by-pass allows the unit maintenance without interrupting the power supply of the loads.
