SIPOS Actuators with efficient combination

Plant protection using UPS systems Whenever a high level of plant operational safety is required, actuator power supply failure must be considered as part of the planning process. As a result, the requirement for fail-safe actuation is now common in many sectors including flood protection, mining, drinking water supply, wastewater treatment and district heating. Typically, battery powered uninterruptible power supply (UPS) systems are adopted: these protect against both power supply interruption and voltage transients. Depending on the requirements, they enable: n controlled 'shut down' of the...

Using single-phase SIPOS actuators with three-phase UPS systems SIPOS actuators, depending on the required positioning force or torque, are available for either single-phase (~ 230 V) or threephase (~ 400 V) operation. In this situation, single-phase actuators are assigned to the individual phases of the UPS system, subject to their power consumption. If the actuators are operated with a ~ 230 V supply then costeffective, single-phase UPS systems can be used. A three-phase UPS system can power several single and threephase actuators to provide a much more cost effective fail-safe system. If a...
