VLT Agro Drive Three-phase frequency controller The VLT Agro Drive enables efficient continuously variable speed control of threephase fans. This control is based on a 0-10 V input signal. The fan speed control can be adapted precisely to the demands of the user. Lower motor temperatures assure a longer lifetime, less maintenance and higher reliability. Furthermore, the energy use is strongly reduced. The VLT Agro Drive provides an optimal climate under all circumstances. Benefits • Energy savings • Very high reliability: ventilation is guaranteed under all circumstances, also with phase-failure or a too high temperature (protection mode). • Until 150 metres protected wire applicable • Applicable in new and existing ventilation systems • Optimal protection against harsh environments such as the air in livestock buildings • Maintenance-free • Optimal climate under all circumstances Characteristics • Three-phase input / Three-phase output • Ruggedized IP55 housing • Seperated cooling and controlling compartment which prevents polluted air to enter the control electronics • Clear graphic display • Special coating of print plate • Complete internal filtering with optimal EMC-protection • Controller resistant against short-circuit on the output • Including memory chip for saving settings • Multiple fans connectable Optional available • Override switch
