Battery-buffered power supply manufacturer: J. Schneider Elektrotechnik GmbH type : AKKUTEC 2403 art.-no. : NBUA 2403 DC-0523G01 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) Nominal input voltage Nominal frequency Nominal output voltage Depending of state of charge of the battery Nominal output current Protective system Secure separation (safe separation between input and output) Operational temperature Short circuit protection Battery Type of battery Battery fuse Back-up time Charging characteristics Charging current at 100% load Charging current at 0% load Deep discharge protection of the battery 24 V AC 47 – 63, Hz 26,8 V DC ± 0,4% 19,8 – 26,8 V DC ± 0,4% 2,85 A at 100% ED current limiting at 1,1 x I Nenn IP 20 According to EN61558-2-17 (VDE 0570 2-17) 0 - 40 ° C optimal storage temperature for battery 20° Durin g C. storage charge battery each 6 month. electronic, short-circuit-proof output External Pb-Akku, maintenance free Pb- Akku maintenance free (Option with modified characteristic curve) External Depending on battery and load I/U DIN 41773 Teil 1 Opt.
