Features

The product is the leading select of chip by our company, using the computer digitization procedure to control the functional movement of the entire machine. It improves many shortcomings of the formerly simulated voltage stabilizer and made the quality of the products to be more reliable, the performance to be more stable, the function to be more formidable.

Q:Use 7812 to make a positive 12V DC power supply Is 220V AC voltage correction 12V: The secondary voltage of the transformer is preferably set to about 12.5V. Because 12.5V sine wave AC voltage peak is 17.6V, after the bridge rectification after 15.2V ~ 15.4V, and 7812 instability voltage is 2V, generally leave about 1V margin is about 3V more appropriate. If the transformer secondary voltage is set to 16V, the peak is 22.6V, after the bridge rectifier over 20V, 7812 to dissipate the power of 8V × output current, when the current reaches the rated 1A, 7812 own power consumption More than 8W, will be very hot, and may even be damaged due to overheating.

Q:Power supply 4.5v can drive 3.6v lithium battery: Can charge. But to the late to be careful, do not overcharge.

Q:What is the working principle of the series DC regulated power supply protection circuit?: First, the current limit ?????? In the circuit back in the middle of a small resistor, such as 1 ohm. ?????? Connect the BE pole of the transistor 9014 at both ends of the resistor. The transistor of the C pole connected to the regulator at the Department. When the current is greater than the design value (such as 800MA), then the resistance at both ends of the detection voltage of 0.8 volts, higher than 0.7 volts, the protection transistor fully conductive, CE short-circuit, the voltage drop to the transistor saturation voltage drop, The At this point, the regulator is shorted and the output voltage drops to near 0 volts. Protection is successful.

Q:What is the meaning of the regulator accuracy?: Regulator accuracy refers to the output voltage fluctuation range is smaller, the higher the accuracy, such as electricity is very unstable, about what low, high precision regulator can be controlled within a safe range, like the computer this Precious equipment requires high precision.

Q:DC power supply is linear or switch: DC power supply with a linear power supply, but also switching power supply.

Q:In the use and installation of the regulator, what should be noted: Second, the security matters ⒈ power supply in the power supply start, do not arbitrarily open the regulator power supply or pull the power supply input and output connections to prevent electric shock or other electrical safety accidents. ⒉ power supply input and output power supply must be arranged reasonable to prevent trampling worn, resulting in leakage accident. ⒊ power supply must be reliable grounding, due to non-ground wire operation caused by electric shock or human injury, by the user responsible for their own. ⒋ power supply can not be connected to the power line in the heating pipes, water pipes, gas pipelines and other public facilities, so as not to infringe the rights of third parties or cause harm. ⒌ should regularly check the power supply input and output connection, so as to avoid loose or fall off, thus affecting the normal use of power supply and safe power. ⒍ voltage regulator cable matching must meet the provisions of the current capacity to carry enough capacity of the cable. ⒎. Regulator should be gently, in the work of time to avoid severe vibration; ⒏, to ensure that the regulator of the carbon brush spring has enough pressure to avoid the carbon brush and coil contact surface flash; ⒐, non-professionals please do not open the regulator power supply or power supply for maintenance.

Q:DC power supply is generally composed of several parts: DC power supply is mainly composed of four parts: power transformers, rectifier circuit, filter circuit and voltage regulator circuit.

Q:Will the DC power supply and DC constant current source of the respective characteristics: Second, the DC constant current characteristics: 1, DC constant current source does not change due to load (output voltage) changes; 2, DC constant current source does not change due to changes in ambient temperature; 3, the internal resistance is infinite (so that the current can be all out to the outside).

Q:Why the output of DC power supply does not allow short circuit: It will burn it out. Regulator is to keep the voltage almost constant. Short circuit will have a lot of current generated, which has a lot of heat, the result is the power is broken.

Q:DC power supply CH1.CH2 two channels with wire connection and not connected What is the difference: This type of CH1 CH2 is output independently. Two channels do not need to be connected. If you want the two channels to be output in parallel or in series, you only need to press the front panel of the parallel button or series button.
