What is the relationship between this tile and kva?
I recommend the use of frequency machines, because the frequency machine with a strong load capacity, but will be more expensive.
10KVA is apparent power, W is active power.
10KVA UPS can take 6000 watts of electrical appliances. Depending on your power factor!
In general, 10KVA high-frequency machine can take 7000W, frequency machine can take 8000W. But if you bring the electrical,
UPS (Uninterruptible Power System), that is, uninterruptible power supply, is a kind of energy storage device, inverter as the main component of the constant voltage constant frequency uninterruptible power supply. Mainly for a single computer, computer network systems or other power electronic equipment to provide uninterrupted power supply. When the mains input is normal, the UPS will be powered by the mains supply to the load, this time the UPS is an AC mains regulator, and it also charge the battery to the machine; when the electricity interruption (accident power failure) , UPS immediately put the battery power, through the inverter conversion method to continue to supply 220V AC load, so that the load to maintain normal work and protect the load soft, the hardware is not damaged. UPS devices are usually protected against excessive voltage and low voltage.
