N+1 Redundant Series by ICT Power

n+1 redundant series ict

Fault Tolerant DC Power Supplies in 12 and 24VDC Output

The ICT N+1 Redundant Series is the solution to your critical power needs. Multiple power modules allow you to design your site power requirements so that your loads will never lose power. If one power module fails, the remaining modules will seamlessly power the load and send an alarm signal.

The ICT N+1 systems are manually switchable between 120 and 220 VAC input voltages and are available in 13.8 and 27.6 VDC output voltages.

They come standard with system monitoring functions through a D-sub connector, with signals such as module ok, over-temperature warning, analog DC output current, fan failure, and AC fail. Each system includes wall mount brackets and a rack mount adapter.

Up to four 450 watt modules can be installed in a single chassis, providing a total of 1,350 watts with redundant protection.

What makes the ICT N+1 Redundant Series different from other solutions is the fact that ORing diodes are used to protect the remaining modules in case of a failure, and the load sharing circuitry is designed in such a way as to never put undue stress on a single module.

Standard Features of the N+1 Redundant Series:

  • True redundancy
  • 120 to 220 VAC manual switch
  • Quick swap modules
  • System status monitoring
  • High efficiency
  • Double-sided circuit boards
  • Precise load sharing
  • Redundant or-ing diode
  • 2 year warranty

More features:

  • Performance and Flexibility
    • The ICT N+1 Redundant Series is designed for mission critical power needs. With up to 4 modules per chassis depending on requirements. True redundant design means that when configured properly, the failure of a power module will not cause any disturbance to the DC load that the power supply is running. Battery backup terminals are provided as standard to provide a float charge with battery revert capability for seamless load transfer if the AC power fails. You can even order a single module version in 12 or 24VDC output and add additional modules later.
  • True Redundant Power
    • An output ORing diode completely isolates a failed power module from the rest of the circuit, preventing harmful feedback to the rest of the system.
  • Reliability
    • The active current sharing allows to balance the load equally across the number of power modules, increasing life expectancy. Premium high quality power connectors support the entire output current without voltage drop. No internal wiring between modules or from modules to the back plane that could reduce the reliability of the system. High quality ball bearing fans for extra long life.
  • Remote Signal Circuitry
    • The ICT N+1 Redundant Series incorporates a DB-25 connector that provides AC and DC power status signals, alarms for fan failure, power module failure, and over-temperature conditions.
