This circuit can be used to control the rotational speed and direction of a series of DC motors. The thyristors Q 1 -Q 4 are connected to a bridge, and each pair on the diagonal is triggered separately. Since the switch S1 is either connected to the coupling transformer T 1 or connected to the T 2 to a pulse circuit, which pair of thyristors are turned on is controlled by S 1 . By turning on Q 2 and Q 3 or Q 1 and Q 4 , the current in the field winding can be commutated. Since the direction of the turned current does not change, if the direction of the exciting current is changed relative to the direction of the rotor current, the direction of rotation of the motor is changed. A pulse circuit is used to drive the thyristor through the transformer T 1 or T 2 . The energy required to trigger the SCR from the capacitor C 1.
Function description
The socket is ordinary converter,with
two output 5V2A power USB power supply at the same time,can be very
convenient in use electrical appliances and recharge the equipment at
the same time,such as digital products like Iphone Ipad,MP3,MP4 etc.The
charge apply to full range of international AC output,no-load power
consumption less than 0.3W,with short circuit,overload,over-voltage
protection,can be convenient for your life and save more energy
Timer Control Time Adgustment
1.Press the power switch 1 time,the 1HOUR LED will light on.The Timer into ON mode,USB and control socket output ON .
2.Continuously press the power switch
the LED light on,the Countdown mode and LED light on will cycle change
from 1HR,2HR,4HR,6HR,8HR,10HR.
3.Choose you need countdown time
mode,the mode LED will lighto on,start countdown until countdown time
finish,the control output and USB change to OFF
4.Then the countdown is start,The Time indicate LED will from high to low auto change until Countdown finish off.
Failure analysis:
1.check whether the power supply connection is good
2.check whether the USB cable is loosen
Warning Note:
1.Use indoor and dry location ONLY
2.The load max does not exceed 15A 3600W
3.This product does not convert voltage please do not miss use DO NOT exceed the maximum loading of 3600 Watts 15A
4.Always have earth connection for safety reason
5.If in doubt please consult with a qualified electrician
