Title:
ELECTRIC LEAKAGE PROTECTION DEVICE AND POWER SUPPLY CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2016039703
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electric leakage protection device and a power supply control device that can be commonly used for two or more types of AC power sources having different effective values in power supply voltage.SOLUTION: In an electric leakage protection device (a power supply control device 1), a self electric leakage generator 28 has a first short-circuit portion and a second short-circuit portion. The first short-circuit portion is configured by electrically connecting a first electric resistance part 280 and a first switch element 281 to each other in series. The second short-circuit portion is configured by electrically connecting a second electric resistance part 282 and a second switch element 283 to each other in series. The first short-circuit portion and the second short-circuit portion are electrically connected to a pair of power supply paths (a voltage-side line L1 and a ground-side line L2) constituting a main circuit in parallel. The electric leakage protection device (the power supply control device 1) is configured as described above, so that the electric leakage protection device can be commonly used for two or more kinds of AC power sources having different effective values in power supply voltage.SELECTED DRAWING: Figure 1
