Integrated MOFSET Functionality Simplifies the Creation of a Redundant Power Supply System
Fail safety, meaning higher machine availability
1+1 redundancy without redundancy module
n+1 redundancy increases utilization of the individual devices
Monitoring the power supply system with communication modules
Whether it’s mechanical engineering, the automotive industry, process engineering, building or power engineering – the Pro 2 redundancy is used when high system availability is required. Additional power supplies are installed as a reserve. If one of the devices fails, the remaining power supplies maintain system operation. Integrated decoupling MOSFETs prevent feedback in a possibly short-circuited power supply output. It also eliminates the need for a separate redundancy module, which enables cost-optimized and space-saving installation.
With 1+1 redundancy, the total load can be supported by a single device, so the device is never overloaded. With n+1 redundancy, the utilization of the individual devices can be increased, which leads to a better overall efficiency. At the same time, in the event of a device failure, n devices assume the additional load resulting from this. This fail-safe power supply system can be easily monitored using pluggable communication modules. There are Modbus TCP, Modbus RTU, IO Link and EtherNet/IP™ interfaces to higher-level control systems.
The redundant 1- or 3-phase power supplies with an integrated decoupling MOFSET basically have the same technical advantages of the entire Pro 2 family. In particular, the TopBoost and PowerBoost features, as well as the high efficiency of up to 96%, are particularly applicable here.
