Uninterruptible power supply backup life
The heart of any UPS system, batteries are electrochemical energy storage devices that convert chemical energy into the electrical energy that the UPS relies on to operate during a power loss. Because their chemicals naturally deplete over time, even UPS batteriesthat are well cared for. Fans are located throughout uninterruptible power supplies and play an important role in cooling critical electronic components such as the inverter and rectifier. In general,.
