ABB LD SYN-101 3BHE005555R0101 Synchronizing Board

FAQ

Q1: How does the synchronizing board detect voltage and frequency differences?
A1: It uses internal sampling circuits to compare generator and grid voltage/frequency and calculates deviations in real time.

Q2: What is the synchronization phase accuracy?
A2: The module achieves phase synchronization accuracy within ±1°.

Q3: How does the module issue grid connection permission?
A3: When voltage, frequency, and phase differences meet preset thresholds, the module outputs a closing permission signal.

Q4: Does the board support communication interfaces?
A4: Yes, it supports RS485 communication and is compatible with Modbus RTU protocol.

Q5: How is the power supplied?
A5: It is powered by a DC 24V control supply, with maximum consumption around 10W.

Q6: Does the module have EMC immunity?
A6: Yes, it complies with IEC/EN 61000 EMC standards for industrial environments.

Q7: What is the operating temperature range?
A7: The operating range is -10 ~ +55°C, suitable for industrial field applications.

Q8: Does it support redundant operation?
A8: Yes, it can operate in parallel with redundant synchronizing modules to enhance reliability.
