Some applications for the Off-Grid energy system monitoring and management solution require specific operating voltages such as 5V, 12V, 24V or 48V. This is enabled with this generic DC/DC converter module, which uses standard DOSA-standard converter bricks. This module in conjunction with such a DC/DC brick enables the addition of fully isolated power sources up to about 600 watts.

DC/DC Converter


  • DOSA-compliant DC/DC module, 1/2, 1/4, 1/8, 1/16 or 1/32 brick
  • Support high-current and digital control converters
  • Output voltage adjust potentiometer (100kΩ)
  • Isolated input and isolated output
  • Output measurement up to 80V and ±60A
  • Backlit LCD to show voltage and current
  • Temperature sensing and proportional fan control
  • Fan RPM monitoring using current sensing
  • CAN-based OGS control® bus to connect with an OGS control® Master
  • 22.5mm, 35mm or 45mm Railbox enclosure
  • Optional internal 24V radial fan (45mm)
