The second generation SINAMICS PM240-2 Power Modules (Frames D and E) provide higher power density and extend the application area of the SINAMICS G120 to 240 V line systems (3-phase 240 VAC) and 500 V to 690 V line systems.
The PM240-2 FSD and FSE replace the previous PM240 Power Modules. An example of space savings is FSD which is 25% narrower than the current design and covers a higher power range, going from 30kW (40Hp) to 37kW (50Hp). Like the FSA-C, removable terminals are provided to simplify commissioning and maintenance time.
Another important goal is to merge the PM240 and PM340 to create a common Power Module platform for both SINAMICS G and SINAMICS S. These Power Modules can be used with firmware V4.7 for the G120 Control Units and with upcoming firmware V4.8 for the S120 Control Units. Today’s PM340 will still be available for some time.
The ability to mount the units side-by-side without derating results in significant panel space savings. Included are variable speed fans which are optimized to load demands resulting in significantly reduced audible noise. Frames D and E have SIL3 ratings.
Utilizing a built-in DC link choke minimizes the need for AC input line reactors and provides for extended drive-motor cabling up to 300m (990 ft. without an AC output reactor).Have an Inquiry for Siemens about this article? Click Here >>
