N+1 Redundancy in DC Power Supply Systems using ICT100-RIM Module
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.

Achieving N+1 Redundancy using ICT100-RIM
The module required to achieve N+1 redundancy in a power
supply system will depend on the specific hardware being used. However, in
general, power supply redundancy can be achieved by using multiple power supply
units (PSUs) and a system that can automatically detect and switch to a backup
PSU if the primary one fails. The ICT 100 Amp Redundant Isolation Module allows
for a safe parallel connection of two DC power supplies or DC-DC converters to
create an N+1 fault-tolerant redundant power system.

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.
