Introducing the YEF Series: Silent, Reliable Fanless Power Supplies
The YEF Series offers dependable, fanless power solutions ranging from 200 to 1000W, making them perfect for sealed enclosure applications. These semi-potted AC-DC power converters eliminate the need for airflow from fans, utilizing baseplate cooling to enhance thermal performance in high-temperature environments.
With power densities reaching up to 14.76W/in³, the semi-potted design enhances rigidity and evenly distributes heat across the PCB, minimizing hot spots and optimizing cooling through the baseplate. This feature is especially beneficial for noise-sensitive applications, outdoor use, and ATEX sealed enclosures where airflow is restricted, helping to maintain low waste heat levels.
Unlike conventional power supplies that dissipate heat through natural or forced convection, the YEF units efficiently transfer heat through their base, allowing for better thermal management.
Each unit includes output adjustment via a potentiometer, accommodating unique voltage requirements or compensating for voltage drops over long cable runs. The YEF Series is equipped with essential protections such as over-voltage, over-current, short circuit, and over-temperature safeguards. Additionally, an optional DC OK indicator and redundancy features are available for critical applications where uptime is essential.
The range supports common rail voltages from 5V to 55V, features output voltage adjustment, operates at 5000M, and achieves efficiencies up to 96%. Designed for outdoor use, these units operate in temperatures ranging from -30°C to 70°C. They comply with household appliance standard EN60335 and offer higher isolation requirements as per EN61558-2-16, ensuring adherence to the Low Voltage Directive and Safety of Electrical Equipment regulations, bearing both CE and UKCA marks.
The 1kW model includes advanced programmable voltage setpoints and constant current limits through an analogue interface.
