Relec now stocking Cotek AD-1500 series offering programmable digital control

The Cotek AD-1500 series, now available from Relec Electronics, are fully digital AC-DC converters that come equipped with configurable modules and user-friendly digital interfaces.

Whether operating in Constant Voltage (CV) or Constant Current (CC) modes, control is via RS485, Ethernet, I2C, or PmBUS interfaces. Each unit also features a built-in EEPROM that retains settings, even after a power outage.

The AD-1500 series is available with a universal ac input range of 90 to 264Vac and 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.

The digital controls in the AD-1500 series make these units suitable for operations requiring quick feedback and the 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

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)

The AD-1500 series offers 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.

Stock for all standard modules and accessories are now available at Relec Electronics.
