Phoenix Contact Uno Power decoupling diode

Click2Contact

The Phoenix Contact Uno Power diode, which is 22.5 mm wide, decouples power supplies connected in parallel, thereby increasing operational reliability.

Due to their high power density, the power supply units in the Uno Power power supply range are suitable for loads up to 100 W, especially in compact control boxes. When used in sensitive applications that require high availability, redundant power supplies are recommended. If the power supplies, which are operated in parallel, are also decoupled by the diode, a short circuit at the output of one of the power supply units or in the supply line from the power supply unit to the diode will have no effect on the load. The diode operates with an input voltage range of 4.5 to 30 VDC and nominal input currents of 2 x 10 A or 1 x 20 A. The module is snapped onto the DIN rail without spacing either side and operates at ambient temperatures from -25 to +70°C, making it suitable for industrial use.

There are 15 corresponding Uno Power power supplies with output voltages from 5-48 VDC currently available. The power supply units reduce energy consumption through low idling losses below 0.3 W and optimised efficiency of over 90%.
