What is APC UPS bypass mode?

What happens when a UPS is in bypass mode?

A static bypass switch automatically and instantaneously transfers the load to the mains electricity supply when there’s an internal fault or failure with the UPS system.

How does a bypass switch work?

The bypass switch monitors the status of the links between its monitor ports and the in-line appliance. If a link goes down, the bypass switch immediately switches into bypass- mode. Some manufacturers of bypass TAPs/switches still send traffic to the appliance during bypass mode.

What can cause a UPS to automatically switch to maintenance bypass?

When the UPS system has an internal failure, failure, or overload, the static bypass switch will automatically convert the load to utility power immediately. It’s a built-in internal bypass and permits a transfer in less than four milliseconds(1/4 of an electrical cycle.

Manual bypass switches are an added benefit to allow service and isolation for safety purposes. Correctly designed systems should enable these operations to be performed without loss of power to the load.

How does a UPS rectifier work?

Rectifier Converts AC voltage to DC voltage, recharges the batteries and maintains float voltage, handles overloads and buffers surges, can accept wide input voltage fluctuations. Inverter Converts DC voltage to AC voltage, regulates and filters AC voltage.

What is passive bypass?

The passive bypass automatically switches the network traffic when an attached inline device has a power failure, which preserves network connectivity.
