PLC is quite like a microcomputer. You can use UPS directly if you can use it on the city bus and the backup ups with your own socket! About 200--300w or so, configure a 500VA on the OK, can delay a 10--20min!
PLC, like other electronic products, has different powers, with enough sizes of UPS,Generally requires more than equipment, maximum power +30% is safe
UPS is an uninterruptible power supply, it is the battery (more than lead-acid battery maintenance) connected with the host, through the host, inverter and other circuit modules to convert DC to urban electricity system equipment. The utility model is mainly used for providing stable and uninterrupted power supply for a single computer, a computer network system or other power electronic equipment, such as an electromagnetic valve, a pressure transmitter, etc.. 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 immediately DC battery energy conversion method by zero switching inverter continue to supply 220V AC power to the load, the load to maintain normal working load and protection of software and hardware is not damaged. UPS devices are usually protected against high voltage or low voltage.And PLC connection to see the wiring requirements.
