wiring and switch
Device working power by AC voltage 220V or charging current transformer power supply, switch trip, the backup power supply directly to the power supply device.
Provide the switch body position, energy storage state, switch position signal to the switch device. In general, these signals are provided in the form of auxiliary contact. The control switch tripping action rated current is 1A/5A, the action of pulse width is 50~200mS. Can also be connected with the permanent magnetic switch.
Device to an external three aviation plug, equipped with No.
Note: the output control loop can not be directly connected to the switch coil, auxiliary switch node should be connected in series to the intermediate circuit, please refer to the detailed method of manual switch.
