Modular UPS solutions

for hazardous areas

R. STAHL

The uninterruptible power supplies (UPS) for hazardous areas ensure the safe operation of systems that require 100% availability. The units are assembled from a modular design kit and can be adapted to specific applications. They can be used to safely bridge complete blackouts or malfunctions in the mains power supply. Stand-by parallel operation types as well as stand-by turn-off operation models can be implemented . Explosion protection is ensured by an integrated Ex UPS guard which monitors the functions of the battery charger and the batteries according to the ATEX directive and according to IEC/EN 60079 ff. It ensures an autonomous supply for a timespan ranging from 30 minutes to several hours. The kit’s component range includes battery chargers, explosion-protected rechargeable batteries (lead gel, NiCd, NiMH), charge monitoring including alarm annunciators, DC power distributors and inverters for various performance classes up to 3,000 VA. It is designed to withstand extreme environments such as extreme heat or cold, high humidity and salt-spray atmospheres.
