DC DC Conduction Basplate CooledConduction & Baseplate Cooled DC-DC Converters for Compact & Fanless Applications

Relec Electronics supplies a wide range of baseplate cooled DC-DC power supplies, specifically designed for environments where space is limited and forced-air cooling is not possible. These fanless DC-DC converters are fully enclosed and operate efficiently within sealed enclosures, ensuring reliable performance in demanding conditions.

Our portfolio covers power ratings from 40W to 3000W, with operating baseplate temperatures ranging from -40°C to 100°C or 105°C depending on the model. Each DC-DC converter with baseplate cooling includes essential protections such as:

  • Input under-voltage
  • Output short circuit
  • Over-temperature protection

All models also feature remote on/off control and output voltage trimming for easy integration and flexibility.

Ideal for Harsh and Compact Applications

These low-profile conduction or baseplate cooled DC-DC converters are well-suited for:

  • Electric and autonomous vehicles
  • Railway systems
  • Telecommunication infrastructure
  • Battery-operated equipment

Relec’s technical team works closely with customers to specify the most appropriate solution based on input voltage conditions, baseplate cooling capacity, and system load requirements.
