If you hook up 240V to the primary, you'll get 48 on the secondary, and so on. (There are practical reasons not to do this. One example: perhaps the windings were only specified to handle 120V, and would fail at a higher voltage.) As far as the 40VA, that is a power rating, not a voltage rating. In a DC circuit, this would be given as 40W (Watts).

The voltage drop will be = 10 A × 2 × 1 Ω = 20 V . Therefore, only 210 V will be available for your appliance. And P = 20 V × 10 A = 200 W will be wasted as heat in the wire. AS/NZS 3000:2018 in Australia and New Zealand specifies the following values: From the LV terminals of a transformer to the final load.
Secure Driving: Our car fridge is equipped with 120/240V AC and 12/24V DC adapters, so you can move the camping fridge seamlessly from home to vehicle. The three-layer battery protection can keep the refrigerator from depleting the vehicle's battery. It is designed to produce low noise and ensures you will sleep well after driving for a long time.

Rated voltage is the max. AC or DC voltage that can be continuously applied at the rated ambient temperature or terminal temperature. In the case of resistors, even at the same rated power, the voltage that can be applied will differ depending on the resistance value, and can be calculated from the rated power and resistance value using the

I have a single phase 5KW generator connected to a diesel engine capable of producing approx 3500 Watts of power. I need to convert the 240V AC to DC in order to send it to my solar charge controller that can accept anything up to 600V DC.
One of them can probably power your loads, with a suitably sized 120/240V transformer. But better to get two for split-phase. 3800W PV, 100 Ah x 48V for 4800 Wh AGM battery. Maximum recommended charge rate is probably 10 or 20 amp, 480 or 960 W. If you use a DC charge controller, it may charge the batteries too fast.
The APSX4048SW 4000W APS X Series 48V DC 220/230/240V AC Inverter/Charger is a reliable power source for a wide variety of tools and sensitive electronics at mobile, emergency and remote sites. With no fumes, fuel or excess noise, it's an excellent alternative to generator power.
1. Converting 240Vac to 12Vdc involves a lot of subsystems. You need an EMI filter, rectifier, and then a step down switching converter (buck, or H-bridge, etc.). Electric blankets just produce heat and you can cost-effectively due that by just putting the incoming AC on a resistive load and avoid power conversion completely and greatly
You might wonder why the United States and Europe use different electric power standards. While the North American electric grid system delivers AC powered at 110-120V with a frequency of 60 Hz, European nations use AC powered at 220-240V with a frequency of 50 Hz. Europe started out mirroring the original US standard at 110V/60 Hz.
That being said, the importance of choosing the best AC to DC converter cannot be overlooked. Here’s why you shouldn’t skimp on quality when choosing a converter… Why You Need the Best AC to DC Converter. The choice of the best AC-DC converter is more than a mere technical decision. It's a commitment to quality and operational excellence.
60 Hz AC resistance values can be 60-90% of these DC resistance values (Reilly 1998). 6 l.2: Thus the majority of research reports consider worst-case (large contact area, wet conditions) total body resistance (limb-to-limb) to be slightly greater than 500 Ohm. Worst-case resistance across the chest can be less than 100 Ohm.
