The figure above shows the voltage start circuit of the inverter. Its main component is Ql. The main function is to provide the start signal for the PWM control chip (TL1451CNS).
When the power is turned on to start the display, the pin 5 of the plug-in CNI receives a high-level turn-on command from the control circuit. This high level is applied to the 4-pin of the startup voltage conversion circuit QI. There are 2 transistors and offsets inside Q1. element. The @ foot is the power supply terminal, the 4 pin is the control signal input terminal, and the 2 pin is the output terminal. At startup, the +14 V voltage supplied by the power adapter is applied to the power supply terminal @ foot of the PWM control chip IC2 through the 2~3 pins of the QI.
Description of Right Angle D-SUB Connector
The right angle d-sub is an ideal connector solution for applications where space is at a premium and there is little to no room for connectivity & cabling. The 90° angle cable exit allows for increased mounting options and versatility of design for those tighter, more compact application needs such as computer servers and industrial robotics.
