(1) Distinguish the original party and the deputy party
When using a voltage regulator, you should first look at the nameplate to find out the adjustment range and maximum allowable current of the primary, secondary, and secondary output voltages. The power supply voltage and working current must not exceed the rated value specified on the nameplate of the regulator.
(2) Wiring rules
Pay attention to the original side and the second side when wiring. Reverse connection will cause a short circuit of the power supply or burn the regulator. The primary and secondary common terminal buttons inside the voltage regulator are connected together. When wiring, connect the center line of the power supply to the primary and secondary common terminal buttons, and the power terminal wire is connected to the other end of the primary side.
(3) How to use
The following good habits should be developed when using: check whether the handle is in the position where the output is zero before closing, gradually increase the output voltage from zero after closing, and monitor the readings of each instrument at the same time, and turn the handle back to zero after the experimental reading is completed. .
1. Distinguish the input terminal and output terminal.
2. Turn the output to the low end before connecting to the power supply.
3. Connect the power supply at the input end according to the requirements of the voltage regulator.
4. Slowly adjust the voltage of the output terminal. Make the voltage at the output end meet the requirements of electrical appliances.
5. Disconnect the power supply of the input terminal
6. Access to electrical appliances
7. Turn on the power supply. At this time, the voltage can be adjusted again as required.
Precautions for the use of voltage regulator1. The wires of the voltage regulator are not allowed to be used in parallel to prevent the sudden shutdown due to insufficient voltage, which will cause huge damage to the machinery;
2. If the brush is found to be excessively worn or defective, the brush of the same specification should be replaced in time, and the number of times the handwheel should be turned under the brush with zero-size sandpaper to make the brush grinding surface smooth and in good contact. use. The replaced copper-graphite composite brush must meet the specifications;
3. When moving the voltage regulator, do not use the handwheel, but use the handle to lift the entire product; 4. The input voltage value must not exceed the rated voltage, so as not to burn the voltage regulator, and the output voltage before shutdown should also be Adjust to 0w; the above four points warn us to check the various accessories carefully when using the regulator, and also remind us to pay attention to the use.
