The module is designed for controlling and managing the power supply circuits of 48VDC automation systems. If there is no voltage at the main input voltage channel, the module switches the power supply of external devices to a standby or emergency source and monitors the battery charge level. When the charge level drops below the threshold value, the module connects the battery to the power supply source.
If there is no voltage at the main input voltage channel, the module switches the power supply of external devices to a standby or emergency source and monitors the battery charge level. When the charge level drops below the threshold value, the module connects the battery to the power supply source. Using the TOPAZ PSC DT Temperature Sensor, the module can monitor the ambient air temperature. If necessary, the module can supply power voltage to the cable heating system.
