To perform an open circuit test, the high voltage (primary) side of the transformer is energized by connecting it to the variable voltage supply terminals as shown in the circuit of Figure 5. In order to obtain open circuit test data, adjust the variable AC voltage supply to its zero voltage position before turning on the AC power switch.

Small variable-voltage power supply units. A characteristic use of autotransformers is illustrated by the following example. In the past, 600 V systems were common within certain industries. The conversion to 480 V could be accomplished by the use of a standard 480 to 120 V transformer.

b) Turn on the power supply and adjust the dc motor rheostat for a motor speed of 1800 r/min. c) Adjust the dc excitation of the alternator until the voltage across the 600( load E1 = 208 . Vac. Measure and record the two other phase voltages E2 and E3. d) Turn off the power supply without touching any of the variable controls.

Step 4: Adjust the output of power supply two to 6.2V, slowly increase it by hundredths of a volt until the battery is disconnected from the circuit. Record the voltage. Step 5: Adjust the output of power supply two to 5.8V, slowly decrease it by hundredths of a volt until the USB output and fan output are disconnected.

Energy Saver (ESS) Feature: The UPS shall continuously monitor the voltage and frequency of the bypass source. When the source parameters are within acceptable limits, the UPS will utilize a minimal/optimal combination of its internal subsystems to ensure acceptable power is always delivered to the critical load, at a system efficiency of 99% or greater, over the range of 10% to 100% load.

Return the voltage to zero and turn off the power supply. Couple the dynamometer to the dc motor/generator with the timing belt. Set the dynamometer control knob at its full mid range position (to provide a starting load for the motor). Turn on the power supply and adjust the variable …
