Reduced investment cost
The remote feeding solution operates on existing copper networks. It does not require any site safety approvals or input stage as it is not connected to the mains. It saves time and money to operators and enables them to quickly offer new services in remote areas. The module is designed to be mounted on a standard din rail or directly on a wall. Snap-in connectors allow quick connection to the load and to the feeding pairs. The module can be quickly and very cost effectively installed in the network as it does not require any connection to the utility network, nor any site safety approvals. The energy system is designed to operate on temperature range from –25°C to 70°C in natural convection.
If the load increases during the life cycle of the application (additional subscribers connected) up to three modules can be paralleled in the field supporting the right level of investment. For higher power loads see also other remote or local feeding solutions from Mitra E&I.
Cost effective reliability
The 60W remote energy solution from Mitra E&I is the perfect answer to provide high availability of power to remote sites in the local loop of the newest networks. The power supply unit connects to copper pairs networks powered at high voltage in the central office equipment. This solution takes advantage of the battery energy back-up power provided centrally. In this way high availability is provided at the remote site without increasing the number of remote battery locations and the exponential costs associated with their maintenance.
Redundancy at all levels
Redundancy can easily be achieved by mounting modules in parallel. Modules can easily be replaced in the field without interruption of power. The number of copper pair connections is designed to power each module independ- ently for most distances. Optional accessory allows battery connection during maintenance or intervention on the net- work.
The remote feeding solution of Mitra E&I is very safe. On the top of standard EN60950-1 it is also designed in com- bination with a central up converter compliant with the IEC/EN60950-21 safety standard. In addition, any circuit fail- ure will shut down the source of power eliminating any risk of electrical shock.
