Battery buffered DC-UPS

Type     :   AKKUTEC 1203
Art.-No.:   NBPAQ33G1M13

Short description

The battery buffered DC power supply of the series AKKUTEC is working according the stand-by parallel mode and ensures in connection with a lead-acid accumulator a safe continuous DC power supply in case of mains failure.
The back-up time is depending from the state of charge of the accumulator and of the discharge current.

The power supply has the following features:

·         Battery charger with I/U-charging characteristics

·         Battery management by micro-controller

·         Battery voltage tracking of the charging voltage by external sensor module (optional)
