R. Stahl takes a new direction in the field of explosion-proof Uninterruptible Power Supply (UPS) solutions for zones 1/21 and 2/22. The 8265/C-TEC line provides backup power from capacitors mounted directly on the PCB. Unlike standard solutions, these UPS 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 robust solutions withstand even very harsh conditions. They tolerate an extremely wide ambient temperature range between -50 and +55 °C.
