Narrow diode for decoupling from power supplies

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

Thanks to their high power density, the power supply units in this power supply range are suitable for loads up to 100W, especially in compact control boxes. When used in sensitive applications that require high availability, redundant power supply concepts are recommended. If the power supplies, which are operated in parallel, are also decoupled from 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 30V DC and nominal input currents of 2 × 10A or 1 × 20A. The module is snapped onto the DIN rail without spacing either side and operates at ambient temperatures from -25 to +70degC, making it suitable for industrial use.

There are 15 corresponding Uno Power power supplies with output voltages from 5 to 48V DC currently available. Thanks to their high power density, they are useful in compact control boxes, where loads of up to 100W are supplied reliably. The power supply units reduce energy consumption significantly compared with other products available on the market. This is achieved through low idling losses below 0.3W and optimised efficiency of over 90 per cent.

Three housings with dimensions of 22.5 or 35 or 55 × 90 × 84mm (width × height × depth) save a lot of space in the control cabinet, thanks to their very high power density of 240W/dm ³. The power supplies for 5, 12, 15, 24, and 48V DC output voltage are available in the 25, 30, 40, 55, 60, 90, and 100W performance class.
