FAQ

Questions Buyers Ask Most

What is 6EP1961-3BA01 used for?＋

6EP1961-3BA01 is a Siemens SITOP PSE201U buffer module that bridges brief interruptions in a 24 V DC supply. It supports a rated output current of 40 A, with backup time dependent on load.

What input voltage does 6EP1961-3BA01 require?＋

6EP1961-3BA01 has a 24 V DC rated input. The Siemens data sheet specifies an allowable input range of 24 to 28.8 V DC; check the upstream supply before installation.

How long can 6EP1961-3BA01 buffer a 40 A load?＋

6EP1961-3BA01 provides 200 ms of backup at 40 A according to Siemens. The published chart also gives 400 ms at 20 A, 800 ms at 10 A and 1.6 s at 5 A; lower loads can extend the time up to 10 s.

How should 6EP1961-3BA01 be installed?＋

6EP1961-3BA01 mounts on a standard DIN rail in a control cabinet. Siemens specifies the standard mounting orientation with the terminals at the bottom and at least 50 mm clearance above and below.

Are the input and output of 6EP1961-3BA01 isolated?＋

6EP1961-3BA01 has galvanic isolation between its input and output according to Siemens. Its enclosure protection rating is IP20.

What does the green LED on 6EP1961-3BA01 indicate?＋

6EP1961-3BA01 shows a green LED when the supply voltage exceeds 20.5 V. If the supply falls below 20.5 V, the LED is off, according to the Siemens equipment manual.

What should be checked when ordering 6EP1961-3BA01?＋

6EP1961-3BA01 should be specified by its complete Siemens article number. Provide the 24 V DC supply details, intended load current, required backup time and quantity so the configuration can be checked against the official load-dependent buffer chart.
