With the redesign of the AEK-3000 High Voltage Series, COTEK introduces an optimized power supply generation for demanding applications. Thanks to the integrated Oring diode and enhanced communication features, system integration is now easier – without the need for external accessories.

What’s new?

• ✅ Built-in Oring diode: reduces signal interference and improves communication performance

• ✅ Series connection capability: scalable output voltage up to 800 V DC

• ✅ RS485 & I²C interfaces: centralized control of multiple power supplies

• ✅ Current sharing in series and parallel mode: flexible configurations up to 24 kW

As before, both output voltage and current (0–105%) can be controlled via analog or digital interface. A free GUI (Graphical User Interface) is available on request for easy setup and control.

Application benefits at a glance:

• High power density in a compact design

• Optimized for modular and decentralized power supply architectures

• Ideal for test systems, battery applications, industrial electronics, and power electronics

The previous models without integrated Oring diode will remain available until mid-2021. We recommend an early migration to the new version – for increased functionality and reduced system complexity.
