【Technical field】

The utility model relates to the technical field of computers, in particular to a temperature control system.

【Background technique】

Because the uninterruptible power supply (Uninterruptible Power System/Uninterruptible PowerSupply, UPS) has the function that when the mains input is normal, the UPS will supply the mains voltage to the load after being stabilized. At this time, the UPS is an AC voltage stabilizer, and it It also charges the battery inside the machine; when the mains power is interrupted (accident blackout), the UPS immediately uses the DC power of the battery to continue to supply 110/220/380V AC power to the load through the inverter switching method, so that the load can maintain normal operation and The feature of protecting the load software and hardware from damage and preventing the loss of information or data interruption is widely used.
