A remote site with limited power supply Flood defense basins are often located a considerable distance from power supplies, leading to long cabling distances. To avoid problems associated with high start up currents in conventional actuators, either ‘oversized’ cables or soft start devices must be used. Oversizing of cables is expensive and soft start devices typically limit actuator output torque, which can be critical on floodgates operated in emergency conditions.
SIPOS actuators are ideally suited, as they do not have a start-up current due to the integrated frequency converter technology.
