Woodward Table B. NetCon Discrete Cables 6 feet, Gray 5416-333

The MicroNet Plus Expansion Chassis may use either single or redundant power supplies.

Each power supply module produces three regulated outputs: 

24 V @ 12 A (max), 5 V @ 32 A (max, derated above

55 degree C external ambient temperature), and 5 V Precharge @ 3 A (max).

A motherboard located on the back of the chassis provides the 

interconnection of the three outputs from each power supply module

into three corresponding power busses: 24 V bus, 5 V bus, and 5 V precharge bus.

The 24 V and 5 V busses are load shared between the two power supply modules.

RTN Expansion Chassis Configurations 

The MicroNet TMR5200 can expand from a single main rack to a maximum 4-rack system by using Remote 

RTN modules and copper or fiber optic Ethernet switches. A maximum of 3 MicroNet Plus expansion racks (14 

slot or 8 slot versions) or MicroNet Simplex racks (6 or 12 slot versions) are supported. If desired, fiber optic 

Ethernet switches can be used to locate each chassis in a different location. It is required to use Woodward 

approved Ethernet hardware for robust operation. 

Ethernet Switch Hardware 

For systems with more than a single RTN module, copper or fiber optic Ethernet switches are required to 

achieve communication and hardware redundancy. Specific Ethernet switches have been tested and 

approved to obtain expansion chassis real time performance and redundancy. 

Due to the critical nature of communications with an RTN expansion rack, it is required to use Woodward 

approved copper and fiber Ethernet switches for robust system operation. At the time of this writing, the 

following hardware part numbers are approved. 

The 5 V precharge bus is not load shared.

Power output regulation at the motherboard, including line, load, and temperature effects,

is less than ±10% for the 24 V bus, +/-5% for the 5 V bus, 

and +/-10% for the 5 V Precharge bus.

The 5 V and 5 V Precharge busses are not for external use.

The 24 V bus is accessible from the motherboard for

external use (protected by 5 A fuses on the source and return lines).
