<p>When considering a reliable power supply unit for industrial and commercial applications, the Single-Phase Series Q model stands out with its robust specifications. Designed to meet rigorous standards, this product ensures both safety and efficiency in diverse environments.</p><p>With a rated current of 5 A and a versatile rated voltage range of 110-300 VDC or 24 VDC, this unit is adaptable to various operational needs. It delivers a solid output with a rated power of 120 W while maintaining an impressive efficiency of 92.7%. This efficiency is complemented by an active harmonic correction feature, ensuring minimal electrical noise and interference during operation.</p><p>The dimensions—40 mm in width, 124 mm in height, and 117 mm in depth—along with its weight of 620 g make this unit compact yet substantial enough for stable installation on DIN rails. Its IP20 degree of protection indicates that it is well-suited for indoor use where dust ingress is not excessive.</p><p>Safety compliance is paramount for any industrial device, and this power supply does not disappoint. It adheres to multiple international standards including ATEX EN 60079, IECEx IEC 60079, UL certifications for both Canada and the USA (UL 508 and UL 60950-1), as well as marine approvals from ABS and DNV. These certifications affirm its reliability across various sectors such as hazardous locations (Class I Div. 2) in North America and marine environments globally.</p><p>Connection integrity is assured through spring clamp terminals which provide secure connections with ease of installation or maintenance. The unit&#39;s active inrush current limitation helps manage initial power surges effectively—rated at either 9 A or up to an impressive peak of 11 A—protecting connected equipment from potential electrical stress during start-up phases.</p><p>Operational flexibility extends across temperatures ranging from -25&#176;C to +70&#176;C with derating beginning at higher temperatures (3 W/&#176;C). This makes it suitable for use in harsh climates without compromising performance significantly due to thermal challenges.</p><p>Additionally, the power reserve type offers a generous buffer at around a remarkable rate of up to 50%, allowing systems some leeway under unexpected load conditions without immediate risk of failure or shutdowns—a critical factor when reliability cannot be compromised.</p><p>In terms of electromagnetic compatibility (EMC), ripple and noise are kept low at just about 50 mVpp ensuring smooth operations free from disruptive voltage fluctuations which could otherwise affect sensitive electronics downstream.</p><p>Overall, whether you&#39;re upgrading existing installations or setting up new ones requiring dependable single-phase solutions within specified parameters—the Series Q model presents itself as an efficient choice backed by comprehensive regulatory endorsements alongside practical features tailored towards demanding industrial landscapes worldwide.</p>
