Yes. Programmable AC sources are commonly used to simulate both 50Hz and 60Hz power conditions for products being sold into different international markets.

Q: What industries use variable AC power sources?

Variable AC power sources are widely used in aerospace, electronics manufacturing, appliance testing, automotive development, renewable energy testing and industrial product validation.

Q: Can this AC source be used for compliance testing?

Yes. Many engineers use programmable AC power sources for compliance testing, product certification and export validation where products must perform under different regional power standards.

Q: Can programmable AC power sources simulate unstable grid conditions?

Depending on the model configuration, programmable AC power sources can be used to simulate voltage fluctuations, frequency variations and abnormal power conditions for product testing.

Q: What products are commonly tested with AC sources?

Common applications include power supplies, motors, household appliances, aerospace equipment, industrial controls, EV components and electronic products.

Q: Can the system be integrated into automated test environments?

Yes. Optional communication interfaces allow integration into automated testing systems and production environments where repeatable testing is required.

Sweep & Ramp Test
The PX-AFV-P series offers an easy and convenient method to execute a single step or continuous output changes. The sweep function is ideal for voltage and frequency variation tests. The response time of voltage and frequency changes are within one cycle. User can also use the ramp function to adjust slew rate of voltage and frequency changes. Ramp function can also effectively reduce the inrush current during motor startup. There are up to 50 memories can be stored and recalled; each memory has 24 steps for user to set up.

Transient Generation
Transient generation is an extended feature that provides the users an easy setup for power line disturbance simulation. Common waveform disturbances such as surge, sag, spikes, and dropouts can be generated for application like immunity.

Intuitive Touch Panel
Users can quickly select the parameters via 4.3 inches touch panel or rotary knob, which provides an easy operation and measure-ment display.

Start/End Angle & High Peak Current for Inrush Current
PX-AFV-P Series is capable of providing high output peak current (max. 4.5 peak/rms). This feature makers it ideal for inrush current happened in motor testing. Users can also define the start and end phase angle from 0° to 360°, which is suitable for switching power inrush testing.

Control Software
PX-AFV-P series provides control software and Labview driver that allow users to easily setup the remote control for the power source without further need of programming.

Fast Slew Rate
For tests like sags, surges, dropouts, or spikes, slew rate is a critical factor. PX-AFV-P series is a high performance AC source that has a high slew rate of less than 300 µs from 0~90% output voltage. It allows users to do pre-compliance test such as IEC-61000-4-11 or MIL-STD-704F.
