General ordering data
Order No. 8951350000
Part designation CP M SNT 180W 24V 7,5A
Version Power supply, switch-mode power supply unit
GTIN (EAN) 4032248742561
Qty. 1 pc(s).
PRO-M = Power-Reliable-Optimized
The optimal and reliable power supply in automation
technology. The solid, very narrow metal housing of the 10
different versions of the 24 V DC supply enable installation
without lateral spacing, thereby saving space on the DIN rail.
AC and DC wide-range inputs and a broad temperature range
allow universal use. Thanks to its high efficiency, overload
resistance and high performance reserves, the PRO-M is the
reliable power supply in all applications. The 3-phase PRO-
M power supply modules continue to work reliable even if one
phase fail, i.e. in two-phase operation.

Notes
Note, technical data *) Recommendation applies only for AC operation; the max. permissible
operating voltage must be observed in all cases! The internal varistor found in a switch-mode power supply
does not replace the need for surge protection within a system.
