Redundant Isolation Module

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.
