AD-1500 Series – 1500 Watts of Programmable Digital control

Our partner Cotek, is pleased to announce the release of their 1500W, fully digital, AD-1500 series ac dc converters, which offer flexibility & programmability through a series of configurable modules and easy-to-use digital interfaces. The AD-1500 series can be operated in constant voltage (CV) or constant current (CC) modes, with full digital control via RS485, Ethernet, I2C or PmBUS interfaces. All units have a built-in EEPROM that remembers settings after a power shutdown.


The AD-1500 series is available with a universal ac input range of 90 to 264Vac, & standard outputs of 12V, 15V, 24V, 30V, 36V, 48V, & 57Vdc. All units have a 5V/1A auxiliary output as standard, which is always on even if the converter is inhibited. All units offer true programmability from 0 – 105% of output voltage and current, making them extremely flexible for low voltage, high current applications such as cathodic protection.

Typical Applications

The control offered by the digital interface makes the AD-1500 series suitable for applications that require fast feedback control and/or close monitoring of the power supply performance and parameters. These include:

  • Industrial – Process Control, Burn-in chambers, Laser, Factory automation, Cathodic protection
  • Battery Charging – EV Charging, Warehouse automation, Retail (Robotics), etc
  • Healthcare – Perfusion, Laboratory, Incubators, etc
  • Ethernet related – Automation, Air traffic control, Financial services, etc

New product highlights

The AD-1500 series builds on the already successful and flexible AE-1500 series and has been developed with futureproofing in mind. The modularity of the control interface means that new features can be added, but still allows for backward compatibility. A graphic user interface (GUI) is currently under construction and will aid developers with the following:

  • Easier Parallel setup & Operation via CANBUS
  • Communication Interface : Single / Standard / Ethernet (coming soon)
  • Communication protocol : PMBUS / MODBUS / RS-485 (UART)
  • Built-in EEPROM to memorize the settings after the power supply has shut down
  • Intelligent GUI to set, monitor, and query the power supply status
  • Built-in ORing-FET and communication isolation circuit
  • 3-stage charging for different battery chemistries (coming soon)


Fully Protected

The AD-1500 series is fully protected against over-current and over-voltage situations, with the protection circuitry always proportional to the voltage and current setpoints. All units are also fully protected against over-temperature (unit shutdown) with auto-recovery once the temperature has reduced.

Design Support

We have a team of dedicated engineers ready to support you throughout the design process. We have stock of all standard modules and accessories on order, which will be available in September 2022, and plan to hold development stock at all times after this date.
