The PSU100D switched-mode power supply systems expand the SITOP power supply portfolio, adding single-phase devices with a good price/performance ratio. The screw-mounted unit from Siemens Industry Automation Division 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, aluminium casing with IP20 degree of protection that requires little space while enhancing mounting flexibility. A wide temperature range from -10 to 70 degrees C. accommodates a broad range of applications in harsh environmental conditions.
The six variants of the power supplies provide a regulated supply of 24 volts with rated output currents ranging from 2.1 to 6.25 amperes (A) and 12 volts with 3 or 8.33 A. Another 24 V version with an output current of 12 A uses a fan for cooling purposes.
For higher outputs, two devices of the same type can be connected in parallel. Single-phase connection to almost any public and industrial supply system is possible thanks to the wide-range input of 85 to 264 V AC, radio interference class B as well as certification in accordance with CE and cULus (Underwriters Laboratories certification for Canada and the USA). All of the devices are UL listed and do not require derating inside of a panel.
The output voltage can be set between 22 and 28 V DC using potentiometers in the 24 V DC variants, and between 11 and 14 V DC in the 12 V DC 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.
