Abstract

PURPOSE: To stabilize operation without the need for specific measures against noise from current transformer power source side by the use of a relay and a transformer which slowly respond to impulsive noise.
CONSTITUTION: The device is provided with the transformer 7 with the primary winding P connected in series to the power supply line for the main device CN1, the relay RL connected to the secondary winding S of the transsormer T, and the subdevices CN2 to CN5 to which power is supplied through the contacts rl1 and rl2 of the relay RL. When the power switch of the main device is closed, a current almost equal to the load current of the main device flows in the primary winding P and a voltage is produced in the secondary winding. The voltage operates the relay and the subdevice undergoes the application of voltage. Also, on the contrary, when the power source of the main device is broken, voltage enough to operate the relay is not produced in the secondary winding and thus the relay is restored and power source to subdevice is also broken.
