Modular UPS solutions for hazardous areas
Product Announcement from R. STAHL, Inc.
Houston – R. STAHL provides uninterruptible power supplies for hazardous areas which ensure the safe operation of systems that require 100% availability. The UPS units are assembled from a modular design kit and can be optimally adapted to specific applications. They can be used to safely bridge complete blackouts or malfunctions in the mains power supply, such as frequency fluctuations or overvoltages caused by lightning strikes which can result in plant downtime. Stand-by parallel operation types as well as stand-by turn-off operation models can be implemented as required by application specifications. Explosion protection is ensured by a special feature which is so far unique on the market: an integrated Ex UPS guard monitors the functions of the battery charger and the batteries according to the ATEX directive and according to IEC/EN 60079 ff, thus allowing for safe operation.
The UPS solutions ensure an autonomous supply to enable ongoing operation of connected systems for a timespan ranging from 30 minutes to several hours. Backup energy units cannot only be used for fixed installations, but also for mobile and portable equipment. The kit's component range includes battery chargers, various explosion-protected rechargeable batteries (lead gel, NiCd, NiMH), charge monitoring technology including alarm annunciators, DC power distributors and inverters for various performance classes up to 3,000 VA. Additionally, R. STAHL provides a wide range of explosion-protected enclosures, such as the GUBox series which features Ex e connection chambers.
Besides solutions based on standard kit components, R. STAHL also provides modules with user-specific explosion protection types as required. Proper certification is included in supply. Thanks to robust components and protective measures, the systems can be designed to withstand extreme environments such as extreme heat or cold, high humidity and salt-spray atmospheres. If required, the performance and functional range of customer-specific UPS systems can be adjusted at any time, even after installation. R. STAHL provides consultation services throughout all implementation and operation phases, including project planning, delivery and commissioning as well as maintenance.
