What is N+1 Redundancy in DC Power Supply Systems?
Globally, the need for greater system availability has
intensified significantly across virtually every industry, from banking,
manufacturing, IT, Healthcare, and many others. System designers are thus
required to guarantee an unprecedented level of equipment uptime. N+1 redundancy in power supply systems is a
common practice used to ensure system reliability and minimize downtime in case
of equipment failure.

In the unlikely event where one of the power supplies experiences an output short to ground failure, the ICT Redundant Isolation Module instantly disconnects the non-functioning power source to prevent the system bus voltage from falling, and prevents large reverse peak currents, which could cause damage to the remaining power supply.

While N+1 redundancy can
increase system reliability, it is not a substitute for proper maintenance and
testing of the power supply system. Regular inspections and preventive maintenance
can help identify potential issues before they cause a failure, which can
further increase the system's uptime and reliability.
