Power Supply with N+1 Redundancy

These High Integrity power supplies are particularly suited for mission-critical applications throughout the process control industry. From emergency shutdown networks to fire and gas protection systems, as well as many general-purpose process control applications

The modular design of the power supply allows the system to be configured in a full, N+1 redundant mode. This guarantees uninterrupted power to your system, even during a module failure and subsequent replacement. The automatic load-sharing feature eliminates load imbalances common in ordinary linear power supplies.

The system is designed with external field connectors for easy cabinet layout as well as LED and alarm output features for quick diagnostic evaluation. The 24 V, 15 A power module plugs directly into a 3- or 6-position chassis which allows a maximum capacity of 45 A or 90 A respectively (30 A or 75 A in N+1 configuration). These high efficiency modules (88% overall) require no internal or external cooling fans; plus, the modules are adjustable from 22.5 V to 28 V for precise voltage selection.
