Frequently Asked Questions
What output does the Mean Well LOP-500-18 provide?
The LOP-500-18 is a 500W open frame AC-DC power supply with a nominal 18V DC output. Its rated output current is 16.7A. This makes it suitable for applications that need a higher-power 18V supply in a compact form factor.
How compact is the LOP-500-18 for space-constrained equipment?
This model uses a 5 x 3 inch footprint and measures 127 x 76.2 x 30.5 mm. The low-profile 30.5 mm height helps when integrating it into equipment with limited vertical clearance. It is designed for applications where both power density and board space matter.
Is the Mean Well LOP-500-18 suitable for industrial or medical equipment?
Yes. The product description lists certifications and standards covering ITE, medical, household, and industrial categories, including IEC 62368-1 and IEC 60601-1. It also features extremely low leakage current and 2 x MOPP, making it suitable for BF medical applications where those requirements apply.
Can the LOP-500-18 operate in harsh temperature environments?
This power supply is rated for operation from -40°C to +80°C, subject to the derating curve. That wide temperature range makes it a strong option for demanding enclosed equipment and industrial environments. Buyers should still confirm the final operating conditions of their specific system.
Does the LOP-500-18 support universal AC input?
Yes. The specified input voltage range is 80 to 264VAC, and it also supports 113 to 370VDC input. This wide input range helps standardize one model across equipment used in different regions and power environments.
What cooling and load capability should buyers know about for the LOP-500-18?
The unit is rated for 320W under convection cooling and up to 500W with 23CFM forced-air cooling. It also supports 150% peak load for 3 seconds. These characteristics matter for equipment with short-duration power surges or tighter thermal conditions.
What protection features are built into the Mean Well LOP-500-18?
The LOP-500-18 includes protection for short circuit, overload, over voltage, and over temperature. The overload mode is specified at 105% to 150% of rated output power with hiccup protection after 3 seconds. These built-in protections help support system reliability in fault conditions.
