21. Modular Static Switches Series STS
Technical information
Input:
- Special versions for nominal input voltage of 24-60VDC and VDC.
- 1x 230VAC bypass mains
- 1x 230VAC inverter output
Output:
- 1x 230VAC, in phase with bypass input

22. Modular Static Switches Series STS
Function
The STS (static transfer switch) monitors two AC inputs (inverter and bypass). If bypass input is within nominal values, the STS synchronises sync bus with bypass mains (inverter follows sync bus). If inverter input is within nominal values and sync bus is in phase with bypass mains the STS switch to priority input without interruption.
If priority input fails, the STS switches over to second input without interruption.
If DC input decreases to battery low level, the STS switch off all connected inverter (at the same time) and switch bypass mains to load.
The STS sends all information (status, measured values) via CAN bus to external monitoring unit.
Display of:
- measured values (DC/AC voltages, output currents, frequency)
- status of connected inverter
- uncoded text for error state (only actual faults)
- time and date
