Frequently Asked Questions
What type of power supply is the Mean Well LOP-400-27?
The Mean Well LOP-400-27 is a 400W low profile open frame AC/DC power supply. It provides a 27V DC output and is built in a compact 5 x 3 inch form factor with a 27.5mm height. This model is intended for embedded OEM and industrial-style equipment where space is limited.
What input range does the LOP-400-27 support?
This model accepts a wide 80 to 264VAC input range and also supports 113 to 370VDC input. It includes active power factor correction, with power factor listed above 0.95 at 230VAC and above 0.98 at 115VAC at full load. That broad input range makes it suitable for equipment intended for global markets.
How much power can the LOP-400-27 deliver under different cooling conditions?
The LOP-400-27 is rated for up to 400W when used with 23CFM forced-air cooling. Under convection cooling, the product description lists 250W output. It also supports 150% peak load for up to 3 seconds, which can help with short-duration load surges.
Is the LOP-400-27 suitable for medical or safety-critical equipment designs?
This model includes IEC60601-1 and ANSI/AAMI ES60601-1 approvals and is described as having 2 x MOPP with extremely low leakage current. The product description also states it is suitable for BF medical applications. Buyers should still confirm the full end-equipment compliance requirements for their specific device.
What protections are included in the Mean Well LOP-400-27?
The LOP-400-27 includes short circuit, overload, over voltage, and over temperature protection. Overload protection is specified at 105 to 150% of rated output power with hiccup behavior after 3 seconds and automatic recovery after the fault is removed. Over-voltage and over-temperature protection use shutdown behavior, with recovery depending on conditions described in the specification.
Can the LOP-400-27 operate in harsh temperature or high-altitude environments?
This power supply is rated for operation from -40C to +80C, with derating referenced in the product data. The description also lists operating altitude up to 5000 meters. Those ratings make it a strong candidate for demanding industrial and enclosed equipment environments, subject to overall system thermal design.
What certifications and standards does the LOP-400-27 support?
The listed safety standards include IEC62368-1, IEC60335-1, IEC61558-1/-2-16, and IEC60601-1, along with approvals from TUV, UL, CCC, RCM, and EAC. The product description highlights use across ITE, medical, household, and industrial categories. This broad certification profile can simplify sourcing for manufacturers serving multiple regulated markets.
