Siemens Supplements Sitop Power Supply Series

Siemens announced that it is supplementing its Sitop power supplies with a new range of stabilized units for the low-end performance range. The four new, primary switched-mode Sitop PSA 100E power packs with 230V connection and rated output currents of 2.5, 4, 6 and 12A meet the basic requirements of the industrial environment. These include the voltage range from 187 to 264Vac, the precisely stabilized output voltage, extensive protection functions against overload, and the compensation of voltage drops on long lines. The output voltage can be set between 23 and 26V for this purpose.

With an MTBF (mean time between failures) value of more than a million hours, the new Sitop PSA 100E power packs are said to be especially reliable and have a particularly long service life. The fan-free devices are suitable for ambient temperatures up to +70°C, and the efficiency level of up to 90% generates low heat loss. The compact metal housing can be snapped onto DIN mounting rails or it can be fixed with screws flexibly on three sides. The removable terminals simplify wiring before installation. The new devices can be used in many sectors and countries and have approvals in accordance with cULus, CB-Scheme and European directives.
