Using the Power Supply, Synchronizing Switch, AC Metering and DC metering Modules connect the circuit shown below. Note that the fixed 120 Volt AC source is connected across one lamp and the variable DC source is connected across the adjacent lamp. Vac = 120 V rms. Vdc = _____ Volts dc Turn on the power supply.

Power Supply. Macro file name: ps.mac Macro names: pwsp2, apwsp2 Version number: NCS 3.1. The PS consists of a transformer, a 3-phase controlled rectifier, and a low pass filter to reduce the noise on the output depicted in Fig. 1.
REGULATED DC POWER SUPPLY
Tables 1 and 2 below describe a method of calculating the resistance values required at different output power levels for a given DC output voltage. Figure 1 shows a simplified schematic of an external AC/DC power supply test set-up using variable resistance as DC load.

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.
