• Voltage Range
Connect the input side of the AC/DC source to the power grid, so that the input voltage is
within the operating voltage range of the power supply, and the output side is connected to a
pure resistive load. Adjust the output voltage value within the rated voltage range, read and
record the measured value on the power analyzer. (Including DC voltage and AC voltage)
• Current Range
Connect the input side of the AC/DC source to the power grid, so that the input voltage is
within the operating voltage range of the power supply, and the output side is connected to a
pure resistive load. Adjust the output voltage value within the rated voltage range to make the
output current reach the rated current value of the power supply, read and record the
measured value on the power analyzer (including DC current and AC current).
•
Frequency Range
Connect the input side of the AC/DC source to the power grid, so that the input voltage is
within the operating voltage range of the power supply. After setting the voltage value,
change the frequency setting of the power supply.
•
Voltage Accuracy
Connect the input side of the AC/DC source to the power grid, so that the input voltage is
within the operating voltage range of the power supply, and the output side is connected to a
pure resistive load. Set the output voltage value to make the power supply work within the
rated output voltage range, read and record the output voltage measurement value on the
power analyzer and the power supply, and take the largest error for calculation.
The voltage accuracy is obtained by the following formula:
And:
