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