Note that: The input voltage may be dropped while the capacitors are being charged before transmission. For accurate data, please check the voltages during TX on and off as well when you check the input voltage of a transceiver unit.
The input voltage monitoring circuit in transceiver unit detects low voltage when AC 100V power source drops to 85V. On the other hand, if the input voltage is 120 to 130V, the over voltage flag is set and an alarm is displayed to monitor.
