<P>A reliable power supply is essential for guaranteeing the productivity of automated plants and machines. This range of <STRONG>Siemens SITOP Uninterruptible Switched Mode Power Supplies</STRONG>, already offer maximum reliability in this respect. But in order to protect 24V loads from longer power failures as well, the power supplies can be upgraded with DC UPS modules.</P><P>For flexible use, there is the <STRONG>SITOP UPS500S</STRONG>. These 15A Basic DIN Rail Units are available in 2.5kW and 5kW versions. A maximum of 3 SITOP UPS501S expansion modules rated at 5kW can be connected in parallel to increase the buffer times. </P><P>The <STRONG>UPS500P</STRONG> is a member of the SITOP family and is intended for the short-time buffering of 24 VDC operated SIMATIC panel PCs. They are available for 5 or 10 kW, and provides up to 7A of output current. The oblong metal enclosure of the UPS module is also suitable for installing on HMI support arms. </P><P>This innovative <STRONG>SITOP UPS500 Range</STRONG> is based on absolutely maintenance free capacitors with a long service life. Even at temperatures of 50&deg;C they still have more than 80% of their capacity after 8 years, so there is no need to replace the energy stores. Because the capacitors do not emit any gas, the control cabinet does not have to be ventilated.</P>
