The Cotek AD-1500 series are fully digital AC-DC converters that set the bar for flexibility and programmability.

These units come equipped with configurable modules and user-friendly digital interfaces. Whether you're operating in Constant Voltage (CV) or Constant Current (CC) modes, control is at your fingertips via RS485, Ethernet, I2C, or PmBUS interfaces. What's more, each unit features a built-in EEPROM that retains your settings, even after a power outage.

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 digital controls in the AD-1500 series make these units perfect for scenarios requiring quick feedback and meticulous monitoring of power supply metrics. Typical applications 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

What's new?

Building upon the successful AE-1500 series, the AD-1500 line is designed with future scalability in mind. The modular control interface not only allows for the addition of new features but also ensures backward compatibility. A Graphic User Interface (GUI) is currently in the works, promising:

Easier Parallel setup & Operation via CANBUS
Communication Interface: Single/Standard/Ethernet (coming soon)
Communication protocol: PMBUS/MODBUS/RS-485 (UART)
Built-in EEPROM to memorise 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 boasts comprehensive protection against over-current and over-voltage events. All units automatically adjust protection levels based on your voltage and current settings. Additionally, the units are safeguarded against overheating, with auto-recovery enabled once temperatures normalise.
