By Anthony Capkun
August 17, 2012 – Siemens Industry Automation Division’s Sitop product family has been expanded with three single-phase 24V power supplies with rated output voltages of 2.5A, 5A and 10A, as well as two 12V power supplies with 7A and 14A. The output voltage of the new PSU100S power supplies is adjustable over a range from 24V to 28V with the 24V power supplies, and from 12V to 15.5V with the 12V models. All devices can supply 1.5X the rated current for five seconds per minute, promising problem-free starting for loads that draw a high current. The 24V versions supply 120% rated current at ambient temperatures up to 45ºC. The power supplies of the Sitop line are designed for standard requirements in automated machines and plants. As for the currently available Sitop smart power supplies, the new single-phase Sitop PSU100S power supplies also feature a signalling contact for evaluating the operating status “Output voltage OK”.
