Ultra-thin Open Frame Non-isolated DC-DC Converter


MORNSUN launched an ultra-thin open frame non-isolated DC-DC converter K78-JT-500R3.

The dimension of K78-JT-500R3 series is 12.50 x 13.50 x 3.50mm, which is 4.75mm lower in height than that of K78-T-500R3 series. Besides, the K78-JT-500R3 series features SMD package, and provides an ultra-wide input voltage range of 4.75 - 36V. This series also eliminates the need for a heat sink and its operating temperature is from -40 to +85°C. What’s more, this series delivers efficiency up to 95%, features low stand-by power consumption and short-circuit protection, which can be widely used for applications in industrial control, electricity, instrumentation industries, etc.
