1-2W Reliable Medical-grade DC/DC Converter with new IC design

Nov 22, 2022 | Product Posts

Medical equipment is different from conventional industrial equipment and daily-use electronic products. It is usually in close contact with the human body. Therefore, higher requirements are put forward for the medical power supplies’ performance, such as quality, safety, and reliability. It is the top priority of enterprises in the whole industry to improve the reliability of medical equipment and its components.

In the current shortage of medical resources, to improve the performance of medical power supplies, Mornsun has upgraded the Medical DC/DC power supplies. We do our best to ensure faster and more stable delivery to provide complete service for the medical industry.

1-2W Reliable Medical-grade DC/DC Converter with newest IC design - G/H_S-R3, G/H_WS-R3 Series.jpg

The newly launched fixed input DC/DC converters R3 series (G/H_S-R3, G/H_WS-R3 series) are based on the original high isolation product line, upgrading with an integrated chip design. It complies with the 3rd medical IEC60601-1 standard, and high isolation voltage is up to 5000VAC/6000VDC. Among them, to meet the power requirements of different medical applications, the G/H_WS-R3 series can meet the 2xMOPP level, and the G/H_S-R3 series can meet the 1xMOPP level.

Advantages

Safety distance

To ensure safety in use, safety standards for medical stipulate the safety distances that must comply at different levels. 

The G/H_WS-R3 product meets the protection level of 2xMOPP, the clearance distance is ≥5mm, and the creepage distance is ≥8mm. 

(At the same time, the technology of Mornsun fixed input DC/DC converter production platform has achieved up to 16mm clearance/creepage distance.)

Leakage current

Low leakage current is one of the core indicators of medical power supply, especially the application of CF type, which requires leakage current ≤ 10μA. 

Mornsun’s G/H_WS-R3 and G/H_S-R3 series’ Low leakage current is ≤ 10μA, and the minimum can be ≤ 2μA.

Reliability

The G/H_WS-R3 and G/H_S-R3 series adopt an integrated chip design.

Compared with the products developed by discrete components on the market, Mornsun’s Power Supply further reduces the use of these discrete components (triodes), effectively improving product reliability. The integration of control circuits can also be flexibly compatible with start-up capability and short-circuit protection. At the same time, the integrated chip has over-temperature protection, which is more conducive to the product’s use in a high-temperature environment.
