We have reviewed the several types of UPS topology previously. Standby, Line Interactive and Online Double Conversion are the most common.
All of these Topologies are just processes for which the UPS delivers backup energy and power conditioning. However, many people get confused with these terms.
Dell has a nice succinct summary....
- Standby - SWITCHES. If there is a problem, it switches over to clean battery power
- Line Interactive - MODERATES. If there is a problem it first moderates the power by bucking or boosting the power to meet the equipment's needs. This is why this this often called Smart
- Online - ISOLATES. If there is a problem, it doesn't care because power problems are fully isolated from the power system
Dell's High Efficiency Online UPS is a hybrid of them all. It has online isolating features when you need them and line interactive features when you dont. If the balancing rock is the moderating line interactive and the lone tree in field is the isolating online.. then maybe this image is the combination:.finite and lonely but bearing the entire human species through the oceans of space and time.
