With the introduction of the RGC..32, Carlo Gavazzi now offers a solution for switching up to 37 AAC at 40°C that fits in the 17.8mm wide platform with a depth of 103mm. The RGC..32 is offered both with screw, as well as box clamp output terminals. The version with box clamps is rated for up to 37AAC @ Ta 40°C. This higher current rating on the 17.8mm compact platform is achieved through the utilization of a higher rated power chip that has an I²t of 18000 A²s. Due to this high I²t specification, the RGC..32 can be protected against short circuits by B curve Miniature Circuit Breakers, in applications where the UL508 SCCR rating is not required.

• Lightning: In fact, transients induced by lightning are not the result of a direct strike. A lightning strike creates a magnetic field that can induce large magnitude transients in nearby electrical cables. A cloud-to-cloud strike can affect both overhead and buried cables. The outcome also is unpredictable—a strike that occurs a mile away can generate 70 V in electrical cables, and another can generate 10 kV from 160 yards away. • Inductive-load switching: Generators, motors, relays, and transformers represent typical sources of inductive transients. Switching inductive loads on or off can generate high-energy transients that intensify in magnitude with increasingly heavy loads. When the inductive load is switched off, the collapsing magnetic field converts into electrical energy, which takes the form of a double exponential transient. Depending on the source, these transients can be as large as hundreds of volts and hundreds of amperes, with durations of 400 ms. Due to varying load sizes, there will be variance in wave shape, duration, peak current, and peak voltage of the transients. Once these variables are approximated, circuit designers will be able to select a suitable suppressor type. • Electrostatic discharge (ESD): This energy is the result of an imbalance of positive and negative charges between objects. It’s characterized by very fast rise times and very high peak voltages and currents.

The issue with the DC heated beds seems slow temperature rise. Some bigger builds and beds need a quicker heatbed heater. (In my opinion not needed for PLA) Only for ABS.

Voltage TransientsVaristors feature high durability, which is essential for withstanding repeated high-peak pulse currents and high-energy surge transients. They also offer a wide voltage range, high energy absorption, and fast response to voltage transients. Peak current ratings range from 20 to 70,000 A, while peak energy ratings range from 0.01 to 10, 000 J.

Jerry is Mobile Nation’s resident nerd and proud of it. There’s nothing he can’t take apart, but many things he can’t reassemble. You’ll find him across the Mobile Nations network and you can hit him up on Twitter if you want to say hey.

Senate Majority Leader Mitch McConnell has been clear that, aside from any spending bills, Republicans’ priority for the end of the year is to keep pushing judges through — and if Flake holds on this issue, it could throw a wrench into that plan.

At the time I tried to get the regulatory authority in NSW to do something about it. Zero interest. Useless idiots.

So the 12 / 24 V designs aren’t an illusion of safety, they are safer if you accidentally short yourself to them

While no standard is perfect, I have found that knowing the NEC and looking carefully at manufacturer listings and labels can save you time, your customers money, and help keep everyone safe.   

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.

Lenovo is announcing a second ARM-powered Windows 10 laptop this week, and this time it’s a Yoga. The Lenovo Yoga C630 WOS (Windows on Snapdragon) is, as you might have guessed, powered by Qualcomm’s latest Snapdragon 850 processor. It’s the first Windows laptop we’ve seen with the Snapdragon 850, and its a chip that Qualcomm specifically designed for always-connected Windows 10 PCs. This new processor ushers in the latest generation of ARM-powered Windows 10 laptops.

Many of the Sony A55 and A33′s settings are accessed via the Fn button, just below and the to the left of the thumb grip recess on the back of the camera. I can’t think of any better place to put it, but accessing it does require loosening your grip, and therefore shifting support from your right hand to your left. Apart from that, the Fn button is in a good location, easy to find by feel: Just slide your thumb down out of its recess, and the Fn button is the first control you’ll touch.
