Frequently Asked Questions
What kinds of low-power devices can the LRS-50-12 supply at 12V?
The LRS-50-12 outputs 12V at 4.2A (50.4W), suitable for powering single-board computers, IP cameras, small 12V fans, access control readers, and compact embedded controllers. Its 99 × 82 × 30 mm footprint makes it practical in space-constrained enclosures.
How does the LRS-50-12 compare to other LRS-50 voltage variants?
All LRS-50 models share the same 99 × 82 × 30 mm case and 0.21 kg weight. Output by voltage: LRS-50-3.3 (33W, 10A), LRS-50-5 (50W, 10A), LRS-50-12 (50.4W, 4.2A), LRS-50-15 (51W, 3.4A), LRS-50-24 (52.8W, 2.2A), LRS-50-36 (52.2W, 1.45A), LRS-50-48 (52.8W, 1.1A). Wattage is roughly similar across models; current scales inversely with voltage.
What is the operating temperature range of the LRS-50-12, and is it suitable for cold-start environments?
The LRS-50-12 operates from -30°C to +70°C, one of the wider ranges in the LRS family. This low-end rating allows cold-start operation in unheated outdoor enclosures or cold-storage facility control panels where temperatures can drop well below freezing.
Does the LRS-50-12 have a universal AC input?
Yes, the LRS-50-12 accepts 85–264VAC, covering 100V (Japan), 120V (North America), and 230V (Europe/international) mains. This universal input simplifies global product variants and procurement across different regional electrical standards.
Which certifications does the LRS-50-12 carry, and are they sufficient for commercial building installations?
The LRS-50-12 holds BSMI, CB, CCC, CE, EAC, RCM, TÜV, and UL certifications. UL listing and CE marking cover the primary requirements for North American and European commercial building and equipment installations.
