Laboratory power supply, you can collect all of the 8 available items. This adjustable power supply allows you to get the output voltage from 1.2 V to 30 V. Circuits Laboratory power supply includes a transformer, rectifier, filter capacitor, the voltage regulator, the output filter. Also, the LED display can be used, but it is better to use a voltmeter or a digital dial. Voltage transformer secondary winding should be at least 24 ... 30 V, and the current - 1.5 A. The main element of the laboratory power supply is the LM317 voltage regulator. It allows you to adjust the output voltage from 1.2 V to 37 V at a load current of 1.5 A. The LM337 voltage regulator is used for regulating the negative voltage. To get bipolar power supply combine two stabilizer, but it should have two transformer secondary windings. Considered laboratory power supply need to close more than 90% of cases, the power of various electronic devices.
