1. Summary

When operating the power supply with an adjusted output voltage, both the output power and output current must be taken into account.

2. The output voltage setting

2.1 Output voltage exceeds the rated voltage

please refer to formula (1) for the maximum output power. The power supply must not be operated beyond its maximum output power rating, as doing so may cause failure due to overheating of internal components.

Maximum output power×Rated output voltage x Rated output current・・・（1）

Example: When the output voltage of the PJA600F-12 is adjusted to 12.5 V
The maximum output current that the power supply is allowed to be operated
=Maximum output power ÷ Output voltage setting
=600W ÷ 12.5V
=48.0A

2.2 Output voltage is less than the rated voltage

Please keep the output current below the rated current even if the output current calculated by formula (1) exceeds the rated value. Exceeding the rated current may cause the overcurrent protection circuit to operate.
