AC Power Sources
Our AC Power Sources span a wide range of power levels for both single phase and three phase requirements. Whether you need just an AC power source or one that has AC AND DC capability, we’ve got you covered.
Our regenerative series ranges from the AGX Series up to 756kVA to the AZX Series up to 1.1MVA. Non-regenerative options range up to 180kW. Smaller units include the LSX Series and CPS100 Series below 5kVA.

Frequently Asked Questions
An AC Power Source, also known as an AC Power Supply, is a specialized test instrument that delivers controlled alternating current (AC) voltage with adjustable parameters such as voltage level, frequency, and waveform shape. It is designed to provide precise and stable AC power for testing, simulating, and validating electrical devices and systems under various operating conditions. AC power supplies are commonly used in laboratories and production environments where programmable and repeatable AC power is required. The term AC Power Sources is sometimes used to indicate more advanced capabilities than supplying a source.
Regenerative power sources like our AZX and AGX series can both source (supply) and sink (absorb) power, feeding energy back to your facility with over 90% efficiency. This reduces operating costs and heat generation compared to traditional power sources that only supply power.
Yes. In fact, there are many benefits aside from the DC capability that are worth considering. For example, the regenerative, bidirectional capability of the AZX/AGX family saves energy costs and manages bidirectional power flows safely.
Yes. Our AC & DC power sources provide integrated AC and DC output capability, eliminating the need for separate test equipment. They can simulate grid-connected AC operation and standalone DC operation in a single unit. The AC+DC mode on select models allow you to add ripple to DC or a DC offset to AC. It’s useful for testing how devices handle noise, voltage fluctuations, or control signals—critical for sensitive electronics, motor drivers, and battery chargers.
Yes, our power sources support wide frequency ranges including 50Hz, 60Hz, 400Hz, and extended ranges up to 5000Hz for global testing standards and specialized aerospace applications.
Four-quadrant capability means our regenerative units can sink and source power, also ideal for testing scenarios with bidirectional power flow. A benefit is being able to manage back-EMF applications such as motors, safely.
