| Has anyone seen this - Voltserver: "Digital Electricity" |

I don't get it. What does this actually do? Are they trying to put 1kW trough ethernet cables? Well... technically if you parallel enough of them... |

--- Quote from: ajb on February 15, 2018, 06:25:27 am ---Reading the articles linked from the website is a bit more enlightening. It seems it's a low voltage power distribution system that has some sort of handshaking between end points and fault protection. The real selling point is that, since it's low voltage (...) They claim up to 1kW, which must be something like 20A @ 48V (...) --- End quote --- No. It is high voltage, low current otherwise you would need thick gauge wire. |

Why does this seem like a cheap re-branding of these existing technologies: https://en.wikipedia.org/wiki/Power-line_communication |

After reading up a bit on the subject: The difference is, that for power lan you have AC current on the line and data packets get modulated on there. Power lan absolutely sucks by the way. I am having one machine connected that way and it is slow and unreliable. The voltserver is more like power over ethernet but with focus on energy transfer, thus giving you the option to use up to 1200W over a CAT6 cable. The amount of data to be transfered is limited though. POE: Lots of data, up to 90W of power PET: Up to 1200W of power, some data for switching applications |

Yes, it's time multiplexing power and data. Or, they pulse power and use a dead time to detect faults. They can use the dead time to transmit data as well. Not an expert in the field, but it sounds quite novel to me. It's only possible with modern electronics. |
