Mornsun Extend R3 Series of DC-DC Converters

Mornsun has recently extended the input range of its 3rd generation (R3 Series) 1W to 2W DC-DC Converters to cover 5V, 12V, 15V and 24V fixed dc inputs. 

Modules are available in industry-standard 3V3, 5V, 9V, 12V, 15V & 24V single outputs, as well as ±3V3, ±5V, ±9V, ±12V, ±15V & ±24V bipolar outputs.

The R3 Series makes use Mornsun’s proprietary internal circuit design which has resulted in improved efficiency, full short circuit protection, large capacitive start up, low standby power consumption and significantly lower cost.  All of this coupled with Mornsun best in class delivery times of 3 – 6 weeks.

Features of the R3 Series DC-DC Converters include:

Continuous output short circuit protection || No-load input current as low as 8mA || Operating temperature range from -40°C to +105°C

Efficiency up to 85% at full load and 78% at light load || CE, CB & UL Certification || Isolation to 1500Vdc (A/B series) & 3000Vdc (E/F series)

DIP/SIP & SMD footprints available || Suitable for RS232/485/CAN bus applications || Ideal for isolated sensors

The R3 Series converters offer 3 key advantages over other technologies.

  • 40% reduction in internal components leads to significantly reduced costs and improved reliability.
  • Traditional push-pull circuits are highly dependent on the characteristics of individual components.  Mornsun’s new IC technology has solved this problem leading to more repeatable output performance.
  • There has always been a trade off between the ability to power capacitive loads and effective short circuit protection.  Mornsun’s R3 Series allows capacitive loads up to 2400uF to be driven whilst still providing full short circuit protection.

Here at Relec we are a happy to offer free of charge samples, many of which we have in stock for immediate delivery.  We will also offer fully technical support to help integrate the converters into your design as well as finding solutions for other aspects of your power topology.

takes innovation very seriously and is an essential part of its development program for the power industry and to bring improved customer experiences.

The use of independent oscillator IC technology leads the path in a new direction of innovation. The R3 series fixed input DC-DC Converters have addressed many of the shortcomings of traditional low-cost components (short circuit protection, large capacitive loads, light load efficiency and over-temperature protection) whilst still reducing costs and maintaining short lead-times of typically less than 4 weeks).
