Companies across the globe in nearly every industry have benefited from the reliable power provided by SITOP power supplies and the available add-on components. Read those stories and learn how to keep your company’s bottom line healthy with SITOP products from Siemens.
El Paso Water saves space, cuts downtime with Siemens 24 V DC UPS (Uninterruptible Power Supply)
EPWater previously depended on a 120 V AC UPS to automatically supply power during outages. The utility did a review of its old UPS and backup battery performance at remote sites. Red flags were raised during the AC UPS audit; the existing systems were bulky, provided no diagnostic information and batteries often failed without warning, ultimately disrupting the water supply. The utility decided to switch to Siemens 24 V DC UPS system. Its remote diagnostics capability lets EPWater know in advance of a pending battery failure. It would also reliably provide backup power to the control system, allowing the PLC to remain energized long enough to provide detailed diagnostic information to central operations. In turn, the information from the 24 V DC UPS and PLC would precisely identify the cause of the problem, giving operations the intelligence to send the right crew to the site with a solution in hand, saving crucial time.
How DC microgrids can keep drill bits turning and well heads producing. Ensuring uninterrupted DC power in upstream oil and gas exploration and production
Of all the world’s many industries, upstream oil and gas exploration and production (E&P) activities are arguably the most ripe for automation given two reasons: First, technology advancements have far outrun their adoption by an industry that
historically has preferred what it considers time-tested production methods – even if those include measuring tank fluid levels with dipsticks and gathering data via clipboards. Second, the economic benefits of those advancements have become too compelling to ignore. That’s especially true for the many producers today whose production costs are rising faster than profit margins.
Commercial Timesharing, Inc. (CTI) or the Poling Group of Companies
The American tire maker approached Siemens to improve and streamline their manufacturing and testing processes. With the help of Totally Integrated Automation (TIA) solutions, CTI was able to improve testing capabilities, simplify maintenance and offer easy-to-use interfaces for users with PC-based control. The solutions provided by Siemens lowered commissioning times and simplified CTI’s automation architecture – all resulting in added features and benefits to the manufacturer and their customers.
The leading U.S. supplier of battery-free Automated Guided Vehicles (AGVs) is providing rugged flexibility and cost savings to their customers through an innovative application of SITOP converters, which some call “portable assembly lines.” These converters weigh less and cost less than industrial batteries, but most importantly allow customers the flexibility to quickly and easily reconfigure production lines. SITOP products are rated for use within a large range of temperatures and environmental conditions.

Prevent 24 VDC Overloads from Stopping Production
How the SITOP Select switch-mode power supply responds to overloads or short circuits, leading to fewer downtimes and failures. Most power supplies completely switch off when an overload is detected, which causes serious problems when they feed multiple loads. SITOP Select protects against overloads when restarting a circuit and allows for simplified troubleshooting.
Technology Evolution: Capacitor-based DC Backup Power
Capacitor-based UPS offers customers a streamlined, reliable, safe, flexible and economical operation. Compared to traditional lead battery DC UPS, a capacitor-based system has lower maintenance costs, longer service life, and is safer for equipment and employees.
Minimize downtimes with all-around protection
Whatever the industry or requirement, a reliable DC power supply system is the basis for any production process or plant. Production processes can be maintained only if a constant power supply is available for the automation system. Often this power supply system is the plant’s Achilles heel and can be responsible for downtimes with high follow-up costs. To ensure maximum profits, you need maximum supply reliability as well as all-round protection against fluctuations in power supply quality, short voltage dips (brownouts), longer power failures lasting up to several hours (blackouts), and fault-specific over-loads of the output circuit.
