TKQ2 双电源自动切换开关Series Dual Power Automatic T(5)

产品说明书

auto controlling circuit, made of MOTOROLA single chip micyoco (SCM) and advanced, reliable electronic component.

1. Working principle of auto controller

The auto controller tests the three phases voltage of normal and reserved power supply in the same time, when the numerical is 110% higher than the rated one, the controller views it as over-voltage, 60~85% lower than the rated one is under-voltage (the user can set the specific parameter freely). The internal circuit judges the test result of the timely phase for six voltages margin. When the result passes the relay, it drives the related relay give the open and close orders to the electricity machinery operating structure. And the above test result will be showed by some LEDs on the panel. There are four working ways (“automatic and manual”, “normal power supply”, reserved power supply”, “release <reclose>”), transfer delay time and the under-voltage numerical can be set through six push button switches. The switches are installed on the panel.

2. Test and control function of auto controller 2.1 self-input and self-recover auto controller

TKQ2 is used for the auto transforming between the normal power supply and reserved power supply. In usual time, the power was supplied by the normal power supply, and when it become abnormal (any single phase is over-voltage, under-voltage, interrupted phase), the reserved power supply will work after the appropriate delay; when the normal power supply refined, it will work once again automatically.

Make sure the reserved power supply is no damaged. When it has some abnormal situation, the related LED on the panel will turn yellow, and the internal buzzer will offer an alarming signal to tell the user to restore.

2.2 自投不自复式auto controller

TKQ2 is used for the auto transforming between the normal power supply and reserved power supply. In usual time, the power was supplied by the normal power supply, and when it become abnormal (any single phase is over-voltage, under-voltage, interrupted phase), the reserved power supply will work after the appropriate delay; when the normal power supply refined, it can’t work once again automatically, unless the reserved power supply has some problem. The situation is also fit for the contrary condition.

Make sure the reserved power supply is no damaged. When it has some abnormal situation, the
