Why should you choose the MORNSUN 305RAC Series?
There are several reasons to choose the MORNSUN 305RAC AC/DC Converters，and here are some key highlights:
● High ability in resisting public power grid voltage fluctuations
● Peak performance even at high-altitude environments (up to 5000m)
● Reliable performance even at extreme temperatures (from -40°C to +80°C)
● High ability to resist cyclic and extreme temp. and constant humidity
● Good EMI performance (CISPR32/EN55032 CLASS B)
We will now review each point in details:
1. Voltage Fluctuations in the Power Supply
Large voltage fluctuations can cause damage to the electrolytic capacitor inside the power supply, especially when the power comes from a generator.
Why choose the MORNSUN 305RAC: the input voltage range of the MORNSUN 305RAC (85-305VAC) ensures that the module is not damaged by any voltage fluctuations.
2. Remote and Harsh Environments at High Altitudes
AC/DC power supplies are often used in remote and harsh environments where the altitude exceeds 2000m or even 5000m.
Why choose the MORNSUN 305RAC: the 305RAC Family has passed a series of tests to verify its reliable operation even in high-altitude environments. Some of the tests performed include: high-temperature altitude test, low-temperature altitude test, aging test, and more.
3. Fluctuations in Temperature and Humidity Levels
The reliability of AC/DC power supplies is essential when dealing with significant temperature swings. The typical working environment for industrial equipment is -25°C- +70°C. However, some environments are more prone than others to severe temperature changes and AC/DC power supplies need to keep pace with the changeful environmental variables.
Why choose the MORNSUN 305RAC: the 305RAC series can uphold reliable operations at working temperatures ranging from -40°C to +80°C. It has also passed a series of humidity tests, including alternating temperature and humidity test, high temperature and high humidity test, constant temperature and humidity test, and more.
4. Electromagnetic Interference
Electromagnetic Interference (EMI) is always a potential problem with switched-mode power supplies - both AC-DC and DC-DC converters - by virtue of their inherent design characteristics. As an engineer, you may be familiar with the several benefits of switched-mode converters, including high efficiency with small size and weight. However, many engineers also struggle with the electrical noise they produce.
Why choose the MORNSUN 305RAC: each of the 305RAC AC to DC converter can withstand the transient surge impact generated from electromagnetic interference conditions, including lighting and surge. Their EMI has also been tested to meet Class A/B standards with a good margin.
What are some applications of the MORNSUN 305RAC Series?
The MORNSUN 305RAC AC/DC Converters are designed to ensure stable and reliable performance under almost any harsh conditions. While the key attributes are consistent among all the AC/DC Converters in the 305RAC Family, their applications can vary according to each industry.
Here below we will examine some of the most prominent applications scenarios for the MORNSUN 305 RAC Series:
1. DC Charging Points
Your challenges: DC charging stations are becoming more widespread as electric vehicles are slowly but steadily replacing their petrol and diesel counterparts. As an engineer, you need to prevent and control any possible large voltage fluctuations of the power grid in harsh environments. When the input voltage rises to 290VAC, the voltage unbalance of the three-phase AC distribution system can cause damage to the electrolytic capacitor inside the power supply.
Our solution: LMxx-23Bxx
2. Street Lighting Controllers
Your challenges: streetlight luminaries require a constant flow of current to promote road safety for drivers and pedestrians in low-visibility conditions. Conventional power supplies with 85-264VAC input can be damaged in harsh environments where the input transient voltage exceeds 264VAC.
Our solution: LDExx-23Bxx
3. Protective Relays
Your challenges: protective relays are often applied directly to the electrical power grid and need to operate under difficult working conditions. In particular, the requirements for EMC protection are among the highest to ensure long-term reliability in protective relays.
Our solution: LO30-23B12E
4. Lighting in Harsh and Hazardous Areas
Your challenges: street lighting in hazardous areas needs to operate continuously despite any atmospheric conditions, including extreme temperatures and high humidity levels. Other challenges of AC/DC power supply applications in street lighting include operating in dusty environments and withstanding large voltage fluctuations.
Our solution: LMF320-23B12
As the name suggests, the MORNSUN 305RAC Series is designed to ensure stable and reliable performance under all conditions. When you choose a MORNSUN AC/DC converter, you can expect reliable performance with limited costs.
