Buffer power supply with capacitors ■ Typically used to bridge momentary interruptions ■ Works as an energy storage device using integrated ultracapacitors ■ When the supply voltage is interrupted, energy from the ultracapacitors is released in a controlled manner ■ A buffer module feeds the load until complete discharge ■ The buffer time depends on the charge state of the capacitor and the discharge current ■ Can only be networked with 24 V devices ■ Maintenance free for life ■ Compactly built into a housing ■ Deep-discharge resistant, thus unlimited shelf life ■ Operation at extreme temperatures possible ■ No gassing, therefore installation in hermetically sealed enclosures feasible ■ Fast availability due to short recharge time after discharge PART NUMBER INPUT Nominal input voltage Stored energy in Ws OUTPUT Voltage output in buffer mode Nominal output current Current limiting Efficiency Ua = 23.5 V DC, la = Inom GENERAL Connection type, input UE and output Ua 2.5 mm2 Connection type, messages I/O 1 mm2 Storage temperature and ambient temperature -40 ... +60 °C Note: The UMG 604-PRO / UMG 605-PRO / UMG 96RM power quality analyzers are supplied by the buffer unit (part no. 1506405) in the event of a momentary interruption of up to 225 sec. For the UMG 509-PRO /UMG 512-PRO power quality analyzers, the expansion unit (part no. 1506406) is also required. A momentary interruption duration of up to 256 sec. can be accommodated here.
