<p><P>PROBLEM TO BE SOLVED: To attain size reduction of distribution board. <P>SOLUTION: A load of a secondary circuit in a voltage transformer is set to a small value corresponding to a case, where a digital apparatus is connected with the secondary circuit. The necessity of additionally connecting a load is eliminated to reduce the voltage transformer and a casing for storing the voltage transformer, thus attaining size reduction in the distribution board. <P>COPYRIGHT: (C)2003,JPO</p> |
