Frequently Asked Questions
What is the output rating of the Mean Well LOP-300-18?
The Mean Well LOP-300-18 provides a regulated 18V DC output rated at 10A, for a total power rating of 300W. It is designed as a low profile open frame power supply in a compact 4 x 2 inch format.
What makes the LOP-300-18 suitable for space-constrained equipment?
This model uses a compact 101.6 x 50.8 x 25.4 mm form factor, which corresponds to a 4 x 2 inch footprint with a low 25.4 mm profile. That makes it a practical choice for OEM equipment where internal space is limited.
What input range does the LOP-300-18 support?
The LOP-300-18 accepts a wide input range of 80 to 264VAC and also supports 113 to 370VDC. This broad range helps it fit equipment intended for use across different regional power systems.
Can the Mean Well LOP-300-18 operate in demanding temperature environments?
Yes. This power supply is rated for operation from -40°C to +80°C, subject to the manufacturer's derating guidance. That wide temperature range makes it suitable for demanding industrial and enclosed equipment environments.
What protection features are included in the LOP-300-18?
The LOP-300-18 includes short circuit, overload, overvoltage, and overtemperature protection. According to the specification, overload protection operates in hiccup mode after 3 seconds, while overvoltage and overtemperature protection shut down output until recovery conditions are met.
Is the LOP-300-18 intended only for industrial equipment, or can it support regulated applications too?
This model is positioned for use across multiple regulated fields because it carries certifications for ITE, medical, household, and industrial safety standards. The description also notes 2 x MOPP and suitability for BF medical applications, which can matter in medical-related equipment design.
How efficient is the Mean Well LOP-300-18?
The LOP-300-18 is specified at up to 94% efficiency. It also features power factor correction and no-load power consumption below 0.5W, which supports more efficient system design.
Does the LOP-300-18 include any support for external cooling accessories?
Yes. The specification lists a built-in 12V/0.5A output for an external fan. The product description also states 180W convection performance and up to 300W with 10.98CFM forced cooling.
