MEAN WELL LRS-350-4.2 Switching Power Supply (4.2V, 60A)

The MEAN WELL LRS-350-4.2 is a unique, enclosed power supply which generates 0-60A at 4.2V with an adjustable 3.6-4.4V range in three consistent output channels from two selectable 100-120 VAC and 200-240 VAC inputs and delivers rated 252W output power with a well efficiency (81.5%) for optimum operation.

The main factors that make Meanwell’s the leading brand AC/DC power supplies worthy are their high durability and stable performance credited to their long lifespan, low profile and space-saving design, and 5G anti-vibration capability (range of 10-500Hz) along all three axes, guaranteeing steady performance in demanding environments, all at a reasonable price.

This AC/DC, low profile LRS-350-4.2 guarantees long-term functioning in challenging situations. Its built-in fan activates when the temperature reaches 50°C and turns off when the temperature falls below 40°C, making it error-free in extreme ambient temperatures ranging from -25°C through +70°C.

These features make the LRS-350 series perfect for mechanical and electrical equipment, industrial applications, and LED equipment requiring consistent and reliable performance. The MEAN WELL LRS-350-4.2 can replace the MEANWELL RSP-320-4.2 and GreatWall GW-LED300Q-4.2. The main difference is that the LRS-350-4.2 uses a selectable AC input range, while the other two models support universal 100-240VAC input. In terms of size, the LRS-350-4.2 is similar to the RSP-320-4.2, while the GW-LED300Q-4.2 is about 20mm taller.

In addition to the developed protections such as overload, over temperature, over-voltage protections (with automatic recovery), and short circuit protection, it is certified by RoHS Directive 2011/65/EU amended by 2015/863 Compliant, EMC Standard: EN55035, and Safety Standards: IEC/UL62368-1, GB4943.1, IEC60950-1, EN61558-1, EN62368-1 which allow it to meet the worldwide energy requirement.
