R. STAHL has introduced an Uninterruptible Power Supply solution for zones 1/21 and 2/22. The explosion-proof 8265/CTEC line provides backup power from capacitors mounted directly on the PCB. And, unlike standard solutions, these systems require no accumulator batteries, which makes the emission of dangerous gases technically impossible.
Since the capacitors can be charged very quickly, the systems are ready for operation within minutes. They can be connected to PCs running a shutdown software via a USB port. The combination of flameproof main enclosures with Ex d ignition protection and Ex e-protected enclosures as connection chambers ensures a very compact and user-friendly design.
The UPS solutions can tolerate an ambient temperature range between -50 and +55°C with an optional extension (the standard range is -20 to +40°C). Even at high temperatures, the systems can reach a service life of 20 years. Compliant with ATEX and IECEx, R. STAHL’s Ex de technology is completely certified.
