Samsung’s 2018 TVs now support FreeSync for smoother gaming | 220v Contactor Relay

With this kind of economy available, I don’t care a bit about all-electric cars. I’m having my cake and eating it, too. Any EV with a sufficiently large battery to meet my traveling needs would be carrying too much unnecessary battery weight (and expense and charging time) to suit my local shopping and errand needs. So the future is already here, and it’s bright. I haven’t felt the need to upgrade my home charging, either. The car recharges in five hours, and I try to get at least that much sleep every night.

Then if one is only looking at getting warm water, then one can also just have the heat pump use ambient indoor temperature to make the warm water. It will efficiently give warm water, but heating the house would be just as efficient as using a large resistor. (But at least the warm water got cheaper. (and it cools down the house during summer if one empties the warm water out doors or down the sink.))

They do not connect 240VAC , they connect 24v DC with a 15A source. Remeber AC is a sine signal, you don’t want a signal that turn off 60 or 50 times per second.

Fast AF. Phase-detect AF doesn’t hunt like contrast-detect, making for fast, smooth AF during movies. (Click to download 4.9MB MP4 file.)

1. 25A for 22A? Too close for my comfort. 2. A thin sheet of aluminum is not much of a heat sink. 3. Sitting on top of the hot water heater means ambient temp is going to be a bit higher. 4. Summer in a garage is likely to get hot.

I don’t know, disassemble an induction heater, use the encased induction coil, feed it with mains, put a metal plate on it, and you got a safe but cumbersome heated bed using mains.

When choosing an appropriate MOV for a specific overvoltage-protection application, the circuit designer must first determine the operating parameters of the circuit being protected, including:

Potential starting relays consist of a high resistance coil and a set of normally closed contacts. The coil is wired between terminals 2 and 5, with the contacts between terminals 1 and 2.

An assessment of a circuit boards durability and or safety should be based on circumstances and consequences and not false assumptions like “this board will only ever have 240Volts supplied to it”.

Not really clear but good point. I met an electrician who told me : ‘230VAC is not dangerous, I’m getting shocked a lot, it really hurts when its 400VAC. Oh by the way, I have to get an appointment for my heart !’

Evil picture, don’t coil your cord tightly around the EVSE, it should hang loosely to dissipate heat
