Cortex DC series: Source or regenerative Source-Sink

Description

The Cortex DC series bidirectional DC power supply is a programmable power supply with source and load functions, automatic 2-quadrant operation, and the ability to absorb energy from the device under test and return it to the grid.

High power density

The power supply can be used as a DC source for validating or testing solar inverters, tracking maximum power point (MPPT) algorithms, and other solar energy systems without relying on actual solar modules or unpredictable weather conditions.

A first-class source is characterized by high power density, such as:

• Power levels of up to 30 kW in a 3U enclosure
• Efficiency of 95%
• Significantly reduced test space requirements that meet commercial office transportation, load-bearing, and distribution requirements
• The Cortex series can simulate the electrical behavior of a photovoltaic (PV) system and mimics the complex current and voltage characteristics of the solar module under various environmental conditions.
• The advanced programmability of the power supply allows the Cortex series to simulate complex and dynamic voltage and current responses of a battery under various load conditions and states of charge. Together with a range of built-in battery type profiles, the source can be used to test, develop, and validate battery-powered systems without the need for a physical battery.

Ultra-high accuracy

The Cortex DC series power supply offers output voltage accuracy of up to ±0.02% F.S. In addition, the DC power supply module features an integrated, independent, high-precision voltage and current measurement system that offers performance comparable to that of a 6½-digit digital multimeter. This configuration saves costs associated with high-voltage and high-precision DC voltage meters, high-precision current meters, power meters, and impedance meters, and increases test efficiency while reducing test costs.
