6 FAQs about [Is the output voltage of the outdoor power supply confirmed to be 220V ]

How do I select a power supply?

Select a model of Power Supply according to your application. Each Power Supply has an input voltage range. Select the Power Supply according to the available input voltage. Output capacity (W) = Output voltage (V) × Load current (I) Select the Power Supply so that the maximum load capacity will be lower than the rated output capacity.

Can a power supply cause overvoltage?

Any internal damage may result in overvoltage depending on the location of the damage. (Stop using the product if dents, marks, or deformation is evident.) Make sure that the input voltage, output voltage, and output current of the Power Supply purchased meet the requirements. (The I/O specifications are provided on the model label.)

What is nameplate output voltage?

Nameplate output voltage is the voltage output of the power supply as specified by the manufacturer on the label on the housing of the power supply.

How does a power supply work?

The output voltage of the Power Supply can be turned ON and OFF from an external signal while the input voltage is being applied to the Power Supply. The allowable range for the ambient temperature in which continuous operation is possible.

Why does my power supply not turn on?

The Power Supply’s load has exceeded the rat-ings, thereby activating the overcurrent protec-tion function. Select a Power Supply capacity that is sufficient for the load current. The output does not turn ON. Output voltage is low. Output indicator is not lit or dim. The Power Supply’s outputs are short-circuited.

How much power can a UUT supply supply provide?

The input voltage source shall be capable of delivering at least 10 times the nameplate input power of the UUT (as is specified in IEEE 1515-2000). Regardless of the ac source type, the THD of the supply voltage when supplying the UUT in the specified mode shall not exceed 2%, up to and including the 13th harmonic (as specified in IEC 62301).
