RS7 main unit is the same unit we use for NS4000 ECDIS Standard. The RS7 computer is based on the Intel® Celeron P4505 processor and has 2 Gigabit Ethernet ports to maintain Internal and External networks connection. The unit has a dual input power supply which will accept both AC and DC input, ensuring that they are compatible with all power systems on all vessels. If both inputs are connected, the units will be powered by AC. If AC power is disconnected, it will automatically switch over to DC without affecting the operation of the unit. It makes it possible to use AC as primary power and a 24V battery as secondary power, eliminating the need for expensive UPS systems when it is approved by Flag and Class. It is also fan-less with no moving parts inside which will prolong lifetime and reduce service costs.


No restrictions for supply new RS7 based TFAP as drop in replacement for existing.
