Continuous Self Calibration
Provides for exceptional accuracy of the AC output Voltage. When enabled, accuracy improves to ±0.03% referenced to the power source internal voltmeter. Programmable Dynamic Output Impedance (optional on UPC12/32)
Programmable Output Impedance provides the operator with dynamic control over the output impedance of the AC Power Source. Using the output current term as conditioned feedback signal to the output voltage circuits, positive or negative impedance may be programmed. The purpose of this control is to simulate the effects of or compensate for high peak current, distribution, or transformer losses of up to ±10% of the output voltage.
This feature creates positive, negative, or zero output impedance (Zo).
- Compensates for line distribution or transformer losses.
- Simulates a soft power line for product testing. Compensation range is ±10% of the output voltage.
Up to 16 different waveforms can be stored in the waveform library for execution as part of a steady state program or for substitution in any output phase as part of a transient test program. Memory location #1 is a non-editable high resolution sine wave. Locations 2-16 are editable and can be substituted in any output phase. An unlimited number of waveforms may be stored on the computer for those using a programmable UPC.
Provides the ability to modify a stored waveform by specifying the waveform amplitude desired at each specific phase angle.
Waveform Analysis (optional on UPC12/32)
Provides both a graphic and numeric display of the harmonic structure of a voltage or current waveform. Data presented includes the magnitude of each harmonic in %, the total harmonic distortion, and the odd and even harmonic distortion in %.
Waveform Synthesis (optional on UPC12/32)
Provides the ability to quickly create virtually any AC Test Waveform that may be required by building it out of harmonics. The process is as simple as keying in the harmonic multiple, the amplitude, and the phase angle for each desired harmonic up through the 51st.
Time Based Transients
Provide the ability to create and execute on command, transients that occur linearly over a specified time segment to modify output voltage or frequency.
Cycle Based Transients
Provide the ability to create and execute, on command, transients that substitute a selected waveform in the output for 1 to 100 cycles.
