ABB SPAU140C Module In Stock
Description
The ABB SPAU140C is a numerical synchro-check relay designed to be used when two power systems are to be connected together. It is a microprocessor-based relay that measures the voltage, frequency, and phase angle of both systems and compares them to preset values. If the conditions are met, the relay outputs a signal that can be used to interlock the circuit breakers of the two systems, allowing them to be connected together safely.
Features:
- Measures voltage, frequency, and phase angle
- Compares values to preset limits
- Outputs a signal for circuit breaker interlocking
- Three-phase or single-phase applications
- Wide voltage and frequency ranges
- Configurable settings
- RS485 communication
- Voltage range: 80-265 V AC/DC
- Frequency range: 45-65 Hz
- Phase angle accuracy: ±0.5 degrees
- Operating time: <20 ms
- Reset time: <10 ms
- Communication: RS485
- Protocol: Modbus RTU
