Warranty Information

GE warrants manufactured products for 24 months new and 6 months repaired.

The CPS3200U Upstream System is a DC/DC converter for line powering FTTN networks, delivering power over telephone lines. It converts -48V DC input to ±190V DC output, with each output safety limited to 100VA and ground fault protected. The system consists of 16 converter/limiter cards in a 2 RU shelf and is designed for applications requiring reliable powering of electronics at a distance from the source. It supports up to 24 shelves managed by a central controller.
