*1. Do not use an inverter output for the Power Supply. Inverters with an output frequency of 50/60 Hz are available, but
       the rise in the internal temperature of the Power Supply may result in ignition or burning.
*2. Refer to Engineering Data on Data Sheet for details.
*3. If the output voltage adjuster (V. ADJ) is turned, the voltage will increase by more than 10% 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. If the output voltage exceeds 28.8 V, all branch outputs will be cut off.
*4. Rated input and output conditions: Rated input voltage, rated frequency, rated output voltage, rated total output
       current, and maximum cutoff output current.
*5. 100% load conditions: Rated output voltage, rated total output current, and maximum cutoff output current.
