For high cycle, high temperature applications, the best options within the SITOP range are the capacitor-based modules. The SITOP CAS modules, available with SuperCap (SuCAP) or lithium capacitor (LiCAP) technology, are designed specifically for frequent cycling and reliable operation at elevated temperatures.  

These modules are maintenance-free, offer fast charging, and provide a long service life – typically up to 15 years. Another strong choice is the SITOP UPS500S, which also uses double-layer capacitors (SuperCaps) for short-term buffering in demanding environments. Both solutions deliver robust, wear-resistant performance ideal for applications requiring numerous charge/discharge cycles and operation in harsh, high-temperature conditions.

For the highest reliability in a SITOP DC-UPS, several features are important.

• Automatic monitoring of batteries or capacitors ensures that the device can provide early warnings about the state of the energy storage and help prevent unexpected failures.
• Intelligent battery management with optimized charging routines, temperature compensation, and regular self-tests prolongs battery life and ensures backup availability. Integrated event and fault signaling - via relay outputs, LEDs, or communication interfaces like PROFINET - enables remote diagnostics and rapid response to any issues.
• A wide temperature operating range and redundancy capabilities, such as support for parallel operation, allow the DC-UPS to function reliably even in demanding or harsh environments.

These features collectively provide the foundation for maximum reliability in mission-critical applications.

SITOP DC UPS modules are also available in explosion-proof versions. They correspond to the Ex ec (increased safety) type of protection for zone 2 (gases, vapors, and mist) and are also an ideal fit for harsh environments thanks to their increased robustness.
