About
The Voltage Converter Single-phase, Upgraded POS-80-RNM is designed for use in manned and cargo spacecraft. It serves to provide stable, high-precision AC power to the single-phase network of spacecraft onboard equipment. This upgraded model, released in 2013, is intended to replace the POS 80 RN voltage converter, which has flight heritage on “Soyuz” and “Progress” space ships. Key features include an output voltage frequency of 1000 Hz. The product is designed for pressurized setup and offers resistance to ionizing radiation of outer space up to 4.5 krad. It has a guaranteed service life of 10 years and can be adapted to customer requirements. The estimated production and delivery time is 6 months. While the previous model has flight heritage, this specific upgraded product does not yet have flight qualification.
