Built for Fanless Environments
Relec Electronics offers a robust range of conduction-cooled AC-DC power supplies and baseplate-cooled AC-DC power supplies, ideal for environments where forced-air cooling is not possible. These fully enclosed solutions are designed to operate efficiently within sealed enclosures or fanless systems.
Our products cover power ratings from 50W to 3500W, with operating baseplate temperatures from -40°C to 100°C or 105°C, depending on the model. Each AC-DC conduction PSU includes protection against input under-voltage, output short circuit, and over-temperature. Key features include remote on/off control and output voltage trimming for flexible integration.
Ideal for Harsh Applications
A baseplate cooled PSU or conduction cooled AC-DC PSU is perfect for use in:
- Military systems
- Railway electronics
- Telecommunication systems
- Laser systems
- Charging stations
We supply AC-DC baseplate PSU for industrial use and work closely with you to ensure the chosen solution matches your input conditions, cooling capability, and load requirements.
With over 40 years of collaboration with trusted suppliers, Relec specialises in conduction cooled AC-DC power supply solutions across a wide range of industries. We carry stock of standard modules and accessories for next-day delivery, and our engineers are ready to support your project from design to deployment.
