The UNO POWER power supply unit impresses in world-
wide use thanks to maximum energy efficiency. Low no-
load losses and the high degree of efficiency save energy.
Thanks to its high power density, the UNO POWER power
supply unit is the ideal solution, particularly in compact con-
trol boxes.
Features
–
–
–
Worldwide use thanks to input voltage range of
85 V AC ... 264 V AC
Maximum system availability through reliable power
supply with 12 V DC
Maximum energy efficiency thanks to optimized
efficiency over the entire operating range of the
power supply unit and low no-load losses
Particularly compact: 55 W of power from this narrow
power supply, which is just 35 mm wide
