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. With the N+1 Redundant Series design, 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.

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 include 19 inch 2RU rack mount chassis, LED indicators for AC and DC status, and system monitoring outputs using a DB-style connector. Battery back-up terminals are provided for float charging an external battery. Built-in revert capability seamlessly switches the load to the battery when AC fails, ideal for communications sites.
