UNO-PS/1AC/24DC/ 30W
Series UNO-PS

UNO-PS/1AC/24DC/ 30W - Power supply unit

Primary-switched UNO POWER power supply for DIN rail mounting, input: 1-phase, output: 24 V DC/30 W

  • Flexible mounting by simply snapping onto the DIN rail
  • More space in the control cabinet with up to 20 % higher power density
  • Maximum energy efficiency, thanks to over 90 % efficiency and extremely low idling losses under 0.3 W
  • Outdoor installation, thanks to the wide temperature range from -25°C to +70°C
