明纬新推出DBUF20/40 20A/40A轨道式备援缓冲模块

2020-11-10 15:52

明纬新推出了轨道式20A/40A备援缓冲模块DBUF20/40系列,可搭配DIN rail电源供应器为负载的短暂备援,当AC市电短暂停电或瞬断时DBUF20/40将会启动缓冲功能提供稳定24确保系统运行,缓冲时间长短则依据负载电流而定,DBUF20在20A条件下可缓冲350ms,DBUF40在40A条件下可缓冲250ms。

DBUF20/40与已上市DR-UPS40不断电备援功能类似,主要特点: 透过内部电解电容储能来提供短暂缓冲时间,不需额外接电池,免定期更换电池可降低系统维护成本。而DC-UPS40则是需外接电池,备援时间可较长但需定期更换电池。DBUF20/40系列推出后,明纬DIN rail外围模块已相当齐全,可提供10~960W 轨道式电源供应器及外围配件模块,提供一站式购足服务!
