All PowerVision switch-mode power supplies feature enormous power reserves thanks to the integrated Power Boost. This ensures a smooth start for consumers with high inrush currents. Additionally, the quick tripping of cost-effective standard circuit breakers is now possible for the first time, thanks to Top Boost technology. The power supplies are equipped with internal input fuses. Using the devices without the usual pre-fuse for equipment protection saves money and space in your system. The three-phase PowerVision switch-mode power supplies are available in three different versions. The electronics monitor the level of input voltages, possible phase failures, frequency, and direction of the rotating field.
