Leaving all other connections intact, disconnect the DC exciter circuit from the fixed, 120 V DC supply and connect it to the variable, 0 – 120 V DC supply (7 – N). Make sure the synchronizing module switch is open and the power supply voltage control is at zero percent and turn ON the power supply.

Turn on the power supply and adjust the variable output voltage to 120Vdc. Readjust the field current using the field rheostat to the value obtained in previous step if necessary. Apply a load to your dc motor by varying the dynamometer control knob until the scale marked on the dynamometer housing indicates 3 lbf.in. (Readjust the power supply ...

Experiment 4: DC Power Supply. I. Introduction. The process of changing AC to DC is investigated in this experiment. An integrated circuit regulator makes it easy to construct a high-performance voltage source using only four parts: a transformer, full-wave bridge rectifier, capacitor filter, and regulator.

The basic requirements of the proposed power supply are as follows. The AC input voltage to the DC power supply is variable providing a maximum voltage and current of 1000VAC at 5A RMS, respectively. The proposed industrial power supply DC voltage is required to regulate its DC output to 50 Volts DC with a maximum current rating of 20 Amps.

A variable regulated power supply, also called a variable bench power supply, is one where you can continuously adjust the output voltage to your requirements. Varying the output of the power supply is the recommended way to test a project after having double checked parts placement against circuit drawings and the parts placement guide ...
