Battery-less UPS solution for hazardous areas Maintenance-free compact Ex de UPS with capacitors for energy storage

The robust solutions withstand even very harsh conditions. They tolerate an extremely wide ambient temperature range between -50 °C and +55 °C (optional extension, standard range is -20 °C to +40 °C). This makes it possible to operate them without restrictions virtually anywhere between the Arctic Ocean and the equatorial region. Even at high temperatures, the 100% maintenance-free systems reach a service life of 20 years. Made from seawater-proof aluminium, the flameproof enclosures can be powder-coated if required, ensuring long-lasting protection especially in rugged maritime climates with moist and salty air. In addition to ship approvals, the UPS units feature many country-specific enclosure certificates for major markets. R. STAHL''s versatile UPS portfolio enables users to specify individual systems ranging from compact to high-performance models. By request, the expert for explosion protection systems also provides extensive engineering support in order to identify savings potentials already in the early planning stages.
