Choosing Between Line-Interactive and Double Conversion Technologies
The choice between line-interactive and double-conversion UPS technologies depends on your equipment’s sensitivity and power requirements. The line-interactive UPS type is more economical and provides adequate protection for environments with minor power fluctuations. These types of UPS are perfect for small and medium-sized businesses with mostly stable power quality.
On the contrary, double conversion (or online) UPS systems provide the highest level of protection as they continuously stabilize incoming power into clean, usable energy by converting it. They serve best with mission-critical applications like data centers or medical equipment, where even the slightest power interruption can lead to significant damage or downtime.
Assess your system’s discomfort levels and use the technology that guarantees optimal reliability for your requirements.
Understanding Sine Wave and Pure Sine Wave Output
The sine wave and pure sine wave outputs pertain to the waveform produced by inverters or UPS systems.
