Akkutec - AKKUTEC 2420-0
DC UPS system 400 V AC to 24V DC / 20A
The battery-buffered DC power supply of the AKKUTEC series works according to the stand-by parallel principle and, in conjunction with a lead-acid battery, ensures that the DC voltage supply is maintained in the event of a power failure.
The DC UPS is characterized by the following properties:
primary switched-mode power supply with I/U charging characteristic
active power factor correction (PFC)
Microcontroller based battery management
Temperature tracking of the charging voltage by external sensor module (option)
Display and control panel for control cabinet door installation or surface-mounting (option)
