Regulator power supply circuit installation and precautions

Installation of regulated power supply circuit:

1. When installing the regulated power supply circuit, first draw the construction design drawing of the regulated power supply circuit. The installation should be carried out according to the design requirements of the drawings to ensure the rationality of the regulated power supply circuit.

2. When the diode is installed, it should be installed horizontally in the order of security. When installing, pay attention to the current direction of the diode if the positive electrode enters the negative pole. Otherwise, when using the power supply, it may cause a short circuit in the circuit and a fire accident.

3. After the diode is installed, the voltage regulator can be installed. When installing the voltage regulator tube, pay attention to installing it horizontally to avoid voltage instability, which may cause damage to other power supply parts.

4, the installation of resistors generally have two ways, horizontal installation and vertical installation. For horizontally mounted resistors, it is best to ensure that the resistors are on the same horizontal line to avoid unevenness in the value of the resistors, resulting in unstable currents that can burn the power components.

5. The installation of the capacitor should be in the vertical installation mode. If other installation methods are used, the circuit capacitance may become smaller, which may not ensure the normal startup of the circuit, so that the regulated power supply cannot work normally. .

6. The three external wires of the circuit board should be connected to the external interface during installation, and it is better to install a heat sink on it. This ensures that the temperature on the board is not too high, resulting in a safety incident.

7. After the power supply circuit is installed, connect its Power Cable to the safety device. When there is a problem in the circuit, it can effectively avoid the occurrence of a safety accident.

8. After the devices of the regulated power supply circuit are installed, the outer casing of the stabilized power supply circuit can be installed. It should be noted that the installation of the regulated power supply circuit components is best ensured to be clean and tidy, so as to avoid the phenomenon of circuit heating, which leads to the occurrence of electrical safety accidents.

Precautions when installing the regulated power supply circuit:

1. Insulation devices must be installed at the bottom of the components to ensure the stability of the components and prevent electric shocks.

2. Before conducting the power-on experiment, the circuit should be tested with a current stylus to avoid short-circuit accidents. In the energization experiment, if the voltage and current of the output and the total resistance of the device are measured by the universal meter, if the voltage and current are abnormal, the experiment should be stopped immediately, and then the device should be disassembled for re-inspection.
