Is this battery powered? What's the input voltage range? What's the power ratings?any body know where i could get a curciut for a 240Vdc to 240Vac inverter? or buy such a device off the shelf...thanks
What's the input voltage range? Minimum to maximum? Or is the voltage always going to stay on exactly 240V? Batteries discharge.240v dc in
A 3KW UPS is not an easy task to build, I have 5KVA UPS which uses 15 battery of 12V current is 26 Amps-h. the size of that UPS is also big with LCD display on it which indicates Voltages freq.,etc....yes battery powered, 240v dc in, 3kw
240VDC is not equivalent to 240VAC even if you swap polarity 50 times a second. You need a 330VDC input due to how AC works, it's 330Vpk (and 660Vpk-pk)240vdc +-10%
That's very cool, I want to see that UPS ..........!!I used to work in a company where we developped DC/AC converters with three different input voltage ranges (and they where only 2,5kVA). It took us 3 years to develop it from scratch.
