The Artesyn Embedded Power NPT40-M series, including the NPT43-M model, offers open-frame AC/DC conversion solutions. This series is designed for versatility, accepting a universal input voltage range of 90 to 264 VAC or 127 to 300 VDC.
Key electrical specifications include a maximum output power of 45W under convection cooling, which can be increased to 55W with forced air. The NPT43-M features three outputs, providing 5V on the main output and +/-15V on auxiliary outputs, each capable of delivering up to 500 mA. It boasts an average efficiency of 75% and includes overload and short circuit protection on all outputs.
Designed for reliability, the NPT40-M series has a demonstrated MTBF of over 550,000 hours. The operating temperature range is from 0°C to 80°C ambient, with derating applied above 50°C. The unit's compact dimensions of 4.00" x 2.00" x 1.10" make it suitable for various applications.
This converter holds ITE and medical safety approvals, including CB and CE certifications, making it suitable for information technology equipment, light industrial systems, and low-power medical, dental, and laboratory applications. It also complies with EMI standards such as FCC Class B and CISPR 22 Class B.
The NPT43-M accepts 90-264 VAC (47-440 Hz) or 127-300 VDC.
Main output: 5V at 500 mA. Auxiliary outputs: +/-15V at 500 mA each.
