The Phoenix Contact 2902879 is an active QUINT redundancy module designed for DIN rail mounting. It features Active Current Balancing (ACB) technology and monitoring functions, ensuring consistent redundancy up to the load. This module is suitable for input voltages of 24V DC and provides output options of 2x40A or 1x80A at 24V DC.
With a compact width of 66mm, height of 130mm, and depth of 125mm, it fits standard DIN rail installations. The module offers a high efficiency of over 98% and operates within an ambient temperature range of -25°C to 70°C. It has a degree of protection of IP20 and meets various safety and EMC standards, including EN 60204-1, EN 60950-1, and EN 50178.
Key features include doubled service life for the redundant solution through uniform load distribution, energy saving, and permanent monitoring of redundancy. The module is also type-tested for startup at -40°C and conforms to EMC Directive 2004/108/EC and Low Voltage Directive 2006/95/EC. It includes a mounted UTA 107 universal DIN rail adapter.
