For a 120KW emergency power supply (EPS), what should be the rated voltage? 400V or 220V? The current capacity calculated for 220V is quite high. Seeking advice

For large capacity applications, a three-phase version should be chosen; otherwise, the power semiconductors will be large and the output cables will need to be thick

380v input cables are generally of this kind; it mainly depends on the usage instructions provided by the equipment manufacturer

It should be 400; it can’t be 2220. Read the instructions carefully

Where is this thing supposed to be used? Let’s take a look

Of course, 400V is used; our largest motors are 200KW in capacity, and all of them use EPS
