Switched-mode power supply: wall mounted, single phase, IP20

Siemens Sitop PSU100D switched mode power supply eliminates traditional rail mounting while meeting basic power supply requirements and is cased in aluminum for IP20 protection.


The single-phase Sitop PSU100D power supplies can be mounted in various positions on the wall, so a mounting rail is not required. Courtesy: SiemensSiemens Industry Inc. introduces the wall-mounted, single-phase, Sitop PSU100D switched-mode power supply. The screw-mounted PSU100D eliminates the need for traditional rail mounting while affordably meeting the basic power supply requirements.

Ideally suited for wall mounting in apparatuses and machines, the PSU100D features a rugged, low-profile, aluminum casing with IP20 degree of protection that requires little space while enhancing mounting flexibility.

A wide temperature range from -10 to 70 C. accommodates a broad range of applications in harsh environmental conditions.

Six fan-free variants provide a regulated supply of 24 V with rated output currents ranging from 2.1 to 6.25 A and 12 V with 3 or 8.33 A. For higher outputs, two devices of the same type can be connected in parallel.

Single-phase connection to almost any public or industrial supply system is possible due  to a wide-range input of 85 to 264 V ac, radio interference class B and certification in accordance with CE and cULus (Underwriters Laboratories certification for Canada and the U.S.).

The output voltage can be set between 22 V and 28 V using potentiometers in the 24 V variants, and between 11 and 14 V in the 12 V variant. A green LED indicates the operating status "Output voltage OK." Electronic short-circuit, overload and overvoltage protection features ensure safety in the event of a fault.
