We all know that UPS (Uninterruptible Power Supply) systems provide backup power during outages. But why do they also need a "Bypass" function? Think of it as an "emergency detour" for your equipment’s power supply.
1. Automatic Protection When the UPS Fails
If a Hidier UPS experiences an internal failure—such as an inverter breakdown or a short circuit—the system could shut down completely, cutting power to connected devices even if the main power grid is still working.
✅ With Bypass: The UPS automatically switches to "Bypass Mode", allowing utility power (mains electricity) to directly feed the equipment, ensuring uninterrupted operation.
2. Safe Maintenance Without Downtime
When technicians perform maintenance, repairs, or part replacements on the Hidier UPS, they can manually activate Bypass Mode.
✅ Result: The equipment continues running on utility power, while the UPS is safely isolated for servicing—no need for a full shutdown.
3. Overload Protection
If the connected equipment suddenly draws more power than the UPS can handle (e.g., due to a power surge or faulty device), the UPS could overheat or get damaged.
✅ With Bypass: The system switches to utility power to prevent UPS failure, protecting both the UPS and the equipment.
