*1. A 100% load for rated input voltage.
*2. Output characteristics are measured at the power supply output terminals.
*3. If the output voltage adjuster (V.ADJ) is turned, the voltage will increase by more than 50% of the voltage adjustment
       range. When adjusting the output voltage, confirm the actual output voltage from the Power Supply and be sure that
       the load is not damaged.
*4. The settings for the output voltage must be within the following range:
       +V: ±1% of the rated value
       –V: ±5% of the rated value
*5. Refer to Overload Protection on Data Sheet for details.
