CPSS/A - TS100 TurboShaft Engine Control Unit

CPSS unit is an electronic device designed for TS100 engine control (produced by PBS Velká Bíteš, a.s. company). This device ensures stable supply of 28V voltage for onboard network.

CPSS controls TS100 gas generator rotations by fuel supply change with the help of free turbine regulator. This fuel supply is ensured by the fuel pump, which is driven by two electric motors placed on one shaft. CPSS activates these motors to be controlled simultaneously to achieve power 1:1 ratio.

If one of the the motors fails or in case of CPSS pump driver failure, the second motor overtakes the power to minimize the TS100 rotations change.

The CPSS unit is controlled via serial CAN bus, or via Uctrl control power voltage. CPSS holds two separate CAN buses intended for the unit control, for diagnostics data outputs and for specified parameters modification via PC or via supreme system.

CPSS enables data collection. Data of failures during operation and running data are recorded.

CPSS is powered by nominal 28VDC voltage.

The CPSS unit is connected to the on-board power (network) via external CPSS-U connector. The connector ensures CPSS disconnection from the on-board system in exceptional on-board network conditions.

The CPSS unit is fit in duraluminium arch shaped case. See the enclosure B.
