UNO2-PS/1AC/24DC/480W - Power supply unit

Primary-switched power supply unit, UNO POWER, Screw connection, DIN rail mounting, input: 1-phase, output: 24 V DC / 20 A, adjustable from 24 V DC ... 28 V DC

  • Save space in the control cabinet, thanks to an extremely narrow overall width of just 59 mm
  • Save energy, thanks to a high degree of efficiency
  • Outdoor installation possible, with a wide temperature range of -25°C … +70°C
  • Simple output voltage monitoring, thanks to the floating DC OK relay contact
