buffer module with maintenance-free capacitor-based power storage device quint-buffer/24dc/20 ? phoenix contact - 07/2006 data sheet interface short-term mains interruptions are bridged by quint buffer, a maintenance-free buffer module on a capacitor basis. systems can therefore also run in unstable networks or are, in the event of failures of a longer duration, correctly shut down after all relevant process data is saved. the bridg- ing time is 200 ms at 20 a and 4 s at 1 a. the buffer module also acts as a power storage device for peak loads and for triggering fuses. for function monitoring, an active switching output and a control lamp are used. with the integrated di- ode, loads can be divided into buffered and unbuffered loads. thus, the buffer period is extended and the buffered consumers are protected against errors in the internal net- work. description danger! components with dangerously high voltage and high stored energy are located in the device! never carry out work on live parts! depending on the ambient temperature and the load, the housing can become very hot! make sure you always use the the latest documentation. it can be downloaded at www.download.phoenixcontact.com . a conversion table is available on the internet at www.download.phoenixcontact.com/general/7000_en_00.pdf . ? maintenance-free due to capacitor-based power buffer ? the slim design saves space on the din rail ? high system availability due to clear signaling ? extended buffer period for critical loads through decou- pled input 102035_03_en
