Quadrant Control
With four-quadrant control, Cortex AC series can test PV inverters, V2G, EV chargers, EVSE, batteries, UPS, and AC/DC power supplies. It has a built-in load option as standard and can operate in any fourquadrant with programmable phase control. It can simulate inductive and capacitive loads, allowing you to test a full range of AC power loads.

The Cortex AC series provides a wide voltage range through a designated power curve so that it can perform the test at the condition of both high and low voltage range.

The Cortex AC series applies advanced power conversion technology to provide AC output as well as DC output modes. The DC maximum average output current is the same as the AC RMS value and can be operated in four quadrant states. That is Cortex AC series have the advantage of higher output power, while a typical AC power supply can only supply half of the AC RMS output value.

RLC network simulation function
In addition to power supply functions, the Cortex AC series can be used as a linear load simulator and for a variety of purposes based on the power regeneration function. The Cortex AC series features up to 12 built-in RLC network models and can simulate linear load characteristics with flexible parameters to test product performance under different impedances, three-phase balanced and unbalanced load modes.
For products that require off-grid testing, such as OBC, UPS, ESS converter, etc., the RLC load function of the Cortex AC series can be used to realize the source-to-load function conversion of the device, which greatly simplifies the ATE hardware configuration and realizes V2G, V2L, V2H and other tests at the same time.

Anti-islanding test function

In addition to grid simulation functions, the Cortex AC Series is an alternative to RLC loads, meeting the diverse test
requirements of modern energy-related industries for linear load simulation, anti-islanding protection, and off-grid
operation.
