Вот сообщение, которое пришло на мыло: Hello all,
While Castle takes all controller failures seriously, many have felt that our response to the incidences of failures in our Phoenix Ice 120HV was taking too long. We didn't make any official statements as we couldn't identify any particular pattern or cause for the failures. Our Repair Dept. keeps track of our returns - for any reason -- and the returns of the 120HV were actually very low; less than 3%. We generally see more than that rate of return just from crash damage unrelated to the controllers. Given that we've produced more than 10,000 of these controllers, a low percentage of failure still results in a lot of upset customers.
We've recently determined that some, again some, setups stress particular components in a way that causes the controllers to fail instantly. The failure mode allows a complete short circuit to occur. Our controllers are designed to carry high currents with as little resistance as possible. This is advantageous when the controllers are operating properly, but this leads to extreme currents and heat when the controllers fail. As the ICE controllers are encapsulated in metal heatsinks, this heat is further concentrated such that physical injuries or property damage may occur.
Our engineers have tested a hardware modification that greatly reduces the risk of this particular failure. We do not recommend using Phoenix Ice 12HV controllers until they have been modified to this new standard.
Please return any 120HV controllers that you may have for one that has this modification. There will be no charge for this exchange.
В кратце - типа мы выпускаем очень надежные регуляторы, но в серии 120HV с отдельными регуляторами возникли сложности. Если у вас такой регулятор пришлите его для обмена.
