- Maintenance and servicing: A UPS system may require maintenance or repairs from time to time. During such occasions, it is necessary to take the UPS offline without interrupting power to the connected devices. An external bypass allows you to divert the power directly from the input to the output without going through the UPS. This way, the UPS can be shut down or serviced while the connected equipment continues to receive power.
- Upgrades and expansions: When upgrading or expanding a UPS system, an external bypass can be used to introduce the new UPS unit without disrupting the power supply to the load. The bypass provides a temporary path for power to flow while the new UPS is being installed and connected to the existing infrastructure. This ensures continuous power availability during the upgrade process.
- Enhanced reliability: In case of a UPS failure or fault, the external bypass allows you to quickly and seamlessly transfer the load to an alternative power source. By bypassing the faulty UPS, you can maintain power supply to the connected devices while troubleshooting or replacing the faulty UPS unit.
- Overload or maintenance bypass: Some UPS systems include a built-in bypass mechanism that allows you to manually switch to bypass mode when the UPS is overloaded or requires maintenance. This can help prevent damage to the UPS or connected equipment. The external bypass acts as an additional layer of redundancy and flexibility, enabling you to switch to bypass mode remotely or automatically based on predefined conditions.
Overall, an external bypass for a UPS provides a way to maintain continuous power supply to critical devices during maintenance, upgrades, failures, or overload situations. It ensures uninterrupted power to the load and offers flexibility, redundancy, and ease of maintenance for the UPS system.
