Step-Diode/5-24DC/2×5/1×10, redundancy module, 5-24 V DC, 2x 5 A, 1x 10 A

Using the redundancy module, it is possible for two power supply units of the same type that are connected in parallel on the output side to increase performance or for redundancy to be isolated from one another.

The reliability of a power supply determines the availability of individual components in a system and whether complex systems can function safely.

Redundant circuits are intended to supply systems that set high demands on operational reliability. Long-term, permanent system availability is ensured by the redundant setup of the power supply.

The power supply of a system can be configured redundantly by switching at least two power supply units in parallel. Together, they then supply the connected devices.

The power supply units involved must be dimensioned to enable the total current requirements of all loads to be covered by one single power supply unit. In the event of an internal device fault or failure of the mains power supply on the primary side, the other device automatically takes over the entire power supply of the loads without interruption.

This means that operational reliability of the entire system can be effectively increased.

Features

• Decoupling power supply units switched in parallel
• Load currents up to 10 A are possible
• Easy mounting by snapping onto the DIN rail or screwing onto the mounting surface
