Is the emergency output voltage of UPS DC or AC?
UPS output is AC, after the city power cut off, the internal inverter part will convert DC to AC, inverter output, and what do not understand, I have contact information in the data. Hangzhou Bo Hong Electronics Co., Ltd.
The 220V AC is supplied to the load by inverting the converter to keep the load working properly and to protect the hardware and software from damage. UPS devices usually provide protection against too large voltages and too low voltages.The 220V continues to be supplied by the inverter to the load, and the UPS output is alternating current!
When the power input is normal, UPS electric voltage supplied to the load, the UPS is an AC power regulator, it is also the built-in battery; when the power interruption (outage), UPS will immediately machine battery power,
UPS (Uninterruptible, Power, System), that is, uninterruptible power supply, is a kind of energy storage device, inverter as the main component of constant voltage constant frequency uninterruptible power supply.
UPS, also known as uninterruptible power supply, voltage output is 220V AC, not DC, so a variety of household appliances, such as computers and other more suitable for use.
