The SITOP UPS500S (5 kWs) is the higher-capacity variant in the capacitor-based DC UPS lineup, delivering double the energy storage of the 2.5 kWs model for applications requiring extended shutdown time windows.

Maintenance-Free Capacitor Technology

Using double-layer capacitors rather than chemical batteries, the UPS500S eliminates periodic battery replacement and control cabinet ventilation requirements. Capacitor aging is minimal: after 8 years at 50°C ambient, more than 80% of original capacity remains available.

Technical Specifications

Scalability and Application

The base unit can be expanded with up to three SITOP UPS501S modules (5 kWs each) for maximum buffer duration. Ideal for database servers, complex process control systems, and automation cells where longer controlled-shutdown sequences are required to preserve data integrity.
