The MORNSUN range includes AC / DC power supplies, AC / DC converters, DC / DC converters, isolation transmitters, IGBT drivers and LED drivers. Thanks to the high reliability, long service life and robustness of the products, they are used in even the most demanding market segments.


Some of the focus products

15 – 500W closed frame power supplies


MORNSUN’s 15W to 500W closed frame power supplies have high efficiency, a wide selection of input and output voltages and pass EMC testing. The products are ideal for a wide range of applications, including industrial controls, building automation, factory automation, energy systems, etc.

What makes this closed frame power supplies so distinctive? There are a number of important factors that are important:


  1. Electromagnetic Immunity: MORNSUN’s power supplies are much less sensitive to electromagnetic interference and meet immunity criteria B for radiation. This will lead to a much more stable application and less interference with other electronic equipment.


  1. Multiple options available: They are available with different options such as PCB coating and protective cover over the terminals.


  1. Simple and reliable production process: Thanks to a well thought-out PCB design, the construction of the PCB is less complex and more automated. This significantly increases the reliability in the final application.


And this is not all! Thanks to our close cooperation with MORNSUN, a large warehouse in Schoten and optimized transport, we can supply the power supplies with short delivery times at a very competitive price.

3 – 15W ultra-thin DC/DC-converters


MORNSUN has launched a new series of ultra-thin DC / DC converters with power ratings of 3W, 6W, 10W and 15W. The URB / VRB_J (M) series offers an ultra-wide input range of 4: 1 and 2: 1. The DC / DC converters are equipped with protection against undervoltage, overvoltage, overcurrent and short circuit.

  • Standby power consumption as low as 0.2W
  • EMI performance that complies with CISPR32 / EN55032 class B.
  • EN62368 and EN60335 approved

3- 200W isolated DC / DC converter R3 series with wide input range


The isolated DC / DC converter R3 series offers a wide input range of 2: 1 or 4: 1 and is available with powers from 3W to 200W. It offers solutions for 5 challenges that regularly come up in power design.

  1. Improved standby power consumption

Industrial electronics sometimes require a very small load. In order to still work within the specifications of the DC / DC converter, a so-called ‘dummy load’ is used that causes a temperature rise.


Solution: With variable frequency technology, the R3 series improves efficiency at low load and eliminates the need for a minimal load. At a low load of 5 to 40%, the converters achieve an efficiency of + 78% and at no load, they have a power consumption of 0.12W. As a result, the converters save energy and minimize the temperature rise.


  1. Shorter start-up times

Most system boot errors are related to the long boot time of the modular power supply. The load can be damaged by the surge voltage during start-up.


Solution: The start-up time of the R3 series has been reduced from 200ms to 20ms and has no overshoot voltage. This prevents system failures caused by a long start-up time, ensures system stability and protects the load from damage.


  1. Meets the correct EMI standard

Most DC / DC converters in the market only meet the EMI class A standard by connecting an external capacitor.


Solution: Most DC / DC converters in the market only meet the EMI class A standard by connecting an external capacitor.


  1. A stable and safe system

Abnormal restart after disconnection from the power supply can cause unnecessary damage.


Solution: The R3 series has an under-voltage input and output over-voltage, over current and short circuit protection. These protections help to ensure the safety and reliability of the system.


  1. Higher reliability

The power supply is the heart of industrial equipment and its reliability is closely linked to the reliability of the entire system. This becomes more important, especially in harsh conditions.


Solution: From design to production, we implement full reliability tests such as a high-temperature operation test, a low-temperature test, a temperature cycle test, a thermal shock test and a vibration test to ensure the performance of the products. The fully automated production ensures the consistency and quality of the products.
