VRF24_DD-50WR4 series has a small size of 25.82*22.80*7.20mm while delivering higher power density and performance improvements compared to conventional products.

VRF24_DD-50WR4 series represents a significant technological advancement, not only in terms of internal circuit technology and performance metrics but also in a breakthrough in the packaging process. This series integrates circuit technology, process technology, and material technology to reduce size while enhancing product performance.

1. Heat Dissipation: By using the double-sided encapsulation process and high thermal conductivity encapsulation materials, the heat dissipation performance of the module is effectively improved.

2. Integration: With the new generation of circuit technology, the product's volume is reduced by 72% compared to industry standard products, and the power density reaches as high as 193W/inch3.

3. Reliability: The design takes into account the stability and safety of the power module, and meets higher reliability test requirements, making the new generation of products more stable and reliable.


1. High power density – provide customers more design flexibility

Compact size of 25.82*22.80*7.20mm, with a power density of 193W/inch3; Compared with the industry's standard 2*1 inch products, the volume is reduced by 72%, the board area is reduced by 55%, and the height is reduced by 39%.It can effectively improve the space utilization of the customer's system.

2. High reliability - complete protection function

VRF24_DD-50WR4 series products have an isolation voltage of 3000VDC, feature input under-voltage protection, output short-circuit, over-current, over-voltage, and over-temperature protections, which ensure that the power supply module will not be damaged under abnormal working conditions. This series of products has also passed a series of reliability tests, such as the "thermal shock test" 500 times under the conditions of -55℃ to +125℃, ensuring the safety and stability of the power supply module and providing more effective protection for customer systems.

3. Stable Supply - fast delivery

VRF24_DD-50WR4 series adopts our self-developed IC, while also ensuring strict control and reserves of raw materials to mitigate any potential supply chain disruptions. This approach ensures stable and reliable lead times, assisting customers to meet the delivery on schedule.


VRF24_DD-50WR4 series can be widely used in communication and industrial control applications.
