UR Rectifier - 1048
INOVAX is a partner of NEOPATH that develops, produces and diversifies its operations in the energy market for Telecommunications, with Rectifier Units (UR) and Rectifier Systems (SR) of 50 wa 2500 w. BCX and UR rectifiers were developed to provide faultless and high quality power supply, developing solutions and adaptations for new products.
UR Rectifier - 1048
The UR – 1048 Rectifier was developed to provide continuous power for telecommunications systems or equipment that operate in the range of 42Vdc to 55Vdc.
This 48 Vdc DC Power Supply Rectifier, UR1048-D, was designed to work in parallel with another rectifier, in a redundant manner, so that, in the event of a failure of one of the rectifiers, the other continues to operate and supply the consumer . The UR1048-D powers the consumers and keeps the battery charged or floating so that any failure in the electrical network does not leave the consumers unpowered.
Although it can be applied in several “niches”, this rectifier was developed to supply equipment in the telecommunications area.
