printing control double-sheet photosensitive circuit

Published:2011/6/5 4:48:00 Author:John | Keyword: double-sheet photosensitive circuit

In the figure, 6.3V of the transformer is used to power indicator and 2.5V of the transformer is used for polymer optical beads. When light exposure of 3DU13 is not blocked, the current can up to 8.5mA. When there is a piece of paper blocks the light, the current is only 5 ~ 6mA. But the relay is still working at this time. When there are 2 sheets of paper blocks the light, the current is only 3 ~ 4mA. And the relay stops working. Utilize this principle to control pharmaceutical printing by working with a single paper. Mechanical action by the relay can drive iron absorption switch of 5kg to take a series of mechanical motion control or to connect alarms to the police.   (View)

DC voltage-stabilizing circuit diagram

Published:2011/6/1 19:47:00 Author:Lucas | Keyword: DC , voltage-stabilizing

The DC voltage-stabilizing circuit in the power supply system is shown as the figure, 170V AC voltage is one-way bridge rectified by KC403, then filtered by the second order II type network, and then it will output 170V DC voltage. The data is uploaded by the 170V DC cable. In order to prevent interference from following circuit on the front-end circuit, each diode in 170V rectifier bridge is connected a 0.1μF capacitor in parallel, in addition, these capacitors can be well absorbed the switching noise from diode. In the power filter circuit, the capacitor voltage value is generally 2 times of the input voltage, and capacitance is relatively large, so that the AC component is filtered out easier, the output voltage is smoother.   (View)
