Maintenance-free capacitors save having to change batteries every year.
Siemens Industry Automation Division has equipped its new uninterruptible 24 volt Sitop UPS500S power supply for direct voltage systems with an innovative capacitor system. This new energy store contains high-capacity, double-layer capacitors, and has a long service life even where ambient temperatures reach 60°C. Depending on needs and the expansion stages, when a power failure occurs, the new 15 A Sitop units guarantee the continued operation of 24 V loads – such as industrial PCs and numerical and programmable logic controls – for up to several minutes.
The units have a degree of protection of IP20 and are designed as standard rail modules for mounting in control cabinets
The basic Sitop UPS500S unit is 120 mm wide. Its capacitors can store either 2,5 or 5 kW seconds of energy, and deliver an output current of up to 15 A, thus converting a 24 V power supply unit into an uninterruptible power supply unit (UPS). Plugging 70 mm wide, 5 kW expansion modules into the basic unit lengthens the buffer time. This ranges from a few seconds to several minutes according to the desired load current and configuration; providing sufficient time to back up important data or ramp down a terminal device in a controlled manner.
The UPS500S can be used in ambient temperatures up to 60°C without maintenance expenditure. For example, the energy storage capacity falls by only 20% over 8 years at an ambient temperature of 50°C. This is a big advantage over lead-acid batteries whose capacity at a cabinet temperature of just 40°C dwindles steadily requiring them to be replaced every year.
These new Sitop power supplies have been tested and harmonised with the Simatic PC system. This ensures that these units are not only ramped down under control but also restarted correctly in all situations. For trouble-free 24-hour operation of PC applications, there is, for example, a system tested combination of new uninterruptible power supplies and the Simatic PC Microbox.
