The use of a central 48/54 VDC power supply compared to decentred separate power supplies has many advantages. First of all it is more economical. Due to the exact dimensioning and scaling these systems are more energy efficient and distinguish themselves by a very low power consumption. It is also very easy to implement redundancy with the central solutions and to use a battery back up (UPS). MICROSENS offers a very compact solution with a high power density which requires a minimum of space only.
