During the maintenance of the UPS, the maintenance bypass switch can ensure that the main circuit part of the UPS can be separated from the bypass power supply circuit, and at the same time ensure that the bypass energy circuit is normally powered to the load. In this way, it can not only maintain the normal load power supply, but also ensure the safety of maintenance personnel. When the UPS equipment fails, it can be switched to the maintenance bypass mode, which is equivalent to short-circuiting the UPS with a cable, and the mains power directly supplies power to the load. At this time, the purpose of repairing the UPS equipment can be achieved. When our UPS power supply fails and needs to be repaired, our equipment cannot be powered off, so a maintenance bypass is used at this time. Our UPS power supply has an input switch and an output switch, as well as a bypass maintenance switch.
The UPS Maintenance Bypass Switch is used in UPS PDU or with large regulator. It allows to manually transfer the connected equipment to utility power via a bypass switch, permitting scheduled maintenance or UPS replacement without power interruption. Combined power distribution feature, it provides maintenance bypass function and power saving within a 19” rack mechanism. A Rack Mounted PDU is a device that can be fitted with multiple outlets to effectively control and distribute electricity.
