Uninterruptible Power Supply
The invention is to provide an uninterruptible power supply that is able to response to diverse output specifications of DC power source units while avoiding increase of numbers of models. DC power source units 30 - 1 and 30 - 2 are placed in a container different from other container that contains an AC power source unit 20 and the AC power source unit and the DC power source unit are detachable. Further, the DC power source units 30 - 1 and 30 - 2 is provided with a setting unit that sets a condition for starting power supply in response to outside operation.
1 . An uninterruptible power supply comprises:
an AC power source unit supplying a AC power to a load; and
a DC power source unit supplying a DC power to a load, wherein
the DC power source unit is placed in a container different from other container that contains the AC power source unit and the AC power source unit and the DC power source unit are detachable together.
2 . The uninterruptible power supply according to claim 1 , wherein
the DC power source unit is provided with a setting unit that sets a condition for starting power supply in response to outside operation.
3 . The uninterruptible power supply according to claim 2 , wherein
the DC power source unit further comprises the setting unit for setting a condition of starting power supply, and the setting unit comprises a DC/DC conversion circuit and an output voltage setting unit, wherein
the output voltage setting unit controls an output voltage of the DC/DC conversion circuit, based on signals output from a controller.
