Esser 581726 PSU 24 V-1 INTEVIO Power Supply and Battery Charging Unit
Product Code: 581726
PSU 24 V-1 is a 19-inch rack-mounted power supply that provides 24 V DC power to the INTEVIO voice announcement system and charges external batteries. Within the EN 54-4 scope, it monitors the battery circuit, performs resistance measurement, and disconnects the battery when voltage drops. LEDs on the front panel, control buttons, and USB socket allow reading of operating values. Since cold start can be performed with battery only when mains power is absent, commissioning is simplified in the field.
