All PowerVision switch-mode power supplies have enormous power reserves thanks to the integrated Power Boost. Problem-free starting of loads with high inrush currents is ensured. Even the fast tripping of low-cost standard line circuit breakers is possible for the first time thanks to the Top Boost technology. The power supplies are equipped with internal input fuses. Using the units without the usual back-up fuse for equipment protection saves money and space in your plant. The three-phase PowerVision switching power supplies are available in three configuration levels. The electronics monitor the level of input voltages, possible phase failures, frequency and rotating field direction.
