Graphcore’s new AI chips are the best-looking server processors you’ll never see | 220v Contactor Relay

The melted solder was probably a secondary failure. When SSRs fail they often turn into heaters as his did and the heat from the base plate itself melted the solder before incinerating the plastic housing.

There is a huge difference between heater and electric motor when it comes to inrush current. But anyway haven’t seen 600A contactor for switching on 60A motor.

Can you please tell me the minimum creepage and clearances between the low voltage and mains side by your standards? How have you done the measurements and decided is not enough? I’m more than happy to hear the story. Ans also again…did you hear about conformal coating and what’s for?

• Pick your features: Models come with either a recoil handle (similar to a lawn mower) or electric push-button start, and one or more outlets to plug in extension cords. Some include covered outlets, illuminated control panels or automatic shutdown in case oil runs low. Portables can weigh from 100 to 250 pounds, so you’ll want to buy a wheel kit. With the wheels installed, a generator can be rolled like a wheelbarrow into place.

In some places, you can get 120 and 240, or you could wire up a large transformer at your mains distribution board and get what ever voltage you wish. Might need to call the local electrician to not loose any legal battles if the house burns down.

If you know the Wattage of the transformer and the input voltage of the oven then you can calculate the approximate current the primary (thicker wire) can carry. Example: 500W 220V gives 500 / 220 = 2.273 Amps. This is the current the coil is designed to carry, and this current should normally take the core close to saturation without generating too much heat. The coil resistance can be measured and an appropriate DC voltage applied. I suggest a current of around 1.5 times as long as the power is not ON permanently. Regarding the use of both coils, the secondary coil is much finer wire and will require a proportionately higher voltage. Assuming the output voltage to be 2500, then the current required will be 500 / 2500 or 0.2 A. The secondary coil has worse properties for dissipating heat, so I would only allow a 25% over current, but just try it and if it gets too hot to hold, reduce the voltage. Allow 20 minutes for the coil to cool between tests. Putting the coils in series, or in parallel does not make sense because they have such different characteristics: better to find two ovens with the same transformer and use both primary coils or both secondary coils, which can then be connected in series to raise the working voltage or in parallel to keep the voltage down but double the current. As someone has already said above, disconnecting the coil produces a spark, that in the secondary coil will be a very high voltage – use a totally enclosed switch rated at at least 250V 10 A, with a 100 Ohm resistor in series with a 0.1 microfarad capacitor across the coil to reduce the sparking and increase switch contact life.

The car can accept up to 48 amps, if you purchase the $500 HPWC. Almost 50 miles per hour. Not needed for us.

If as the report says. there’s little rear leg room and is being marketed for a 2 person family, then the answer is no.

By the way, the plug-in Kia Niro appears very similar to the now-discontinued plug-in Ford C-Max. I wish Kia better success with their product offering than Ford had with theirs.

Later while an engineering student I worked in a factory where they built video projection systems with a 30kV final anode voltage

Built by creative agency redpepper, There’s Waldo zeroes in and finds Waldo with a sniper-like accuracy. The metal robotic arm is a Raspberry Pi-controlled uArm Swift Pro which is equipped with a Vision Camera Kit that allows for facial recognition. The camera takes a photo of the page, which then uses OpenCV to find the possible Waldo faces in the photo. The faces are then sent to be analyzed by Google’s AutoML Vision service, which has been trained on photos of Waldo. If the robot determines a match with 95 percent confidence or higher, it’ll point to all the Waldos it can find on the page.

the scariest thing I have ever seen/been around was in a fuel terminal at an oil refinery. I couldn’t figure out why we had printers, plotters, Apple II’s and monitors dropping like flies.
