Frequently Asked Questions
What 48V loads are appropriate for the LRS-75-48 at 1.6A?
At 48V and 1.6A (76.8W), the LRS-75-48 suits powering single PoE injector ports, 48V control relay circuits, compact 48V DC–DC converter inputs, and low-power 48V fieldbus communication nodes. It is well-matched for systems that need a regulated 48V rail at modest current.
How does the LRS-75-48 compare to the LRS-50-48 and LRS-100-48?
All accept 85–264VAC. The LRS-50-48 (99 × 82 × 30 mm, 0.21 kg) delivers 52.8W at 1.1A. The LRS-75-48 (99 × 97 × 30 mm, 0.23 kg) delivers 76.8W at 1.6A. The LRS-100-48 delivers 110.4W at 2.3A. The LRS-75-48 fills the middle tier for 48V applications requiring more than 1.1A but not the full 2.3A of the LRS-100-48.
What operating temperature range does the LRS-75-48 support?
The LRS-75-48 operates from -30°C to +70°C and withstands 5G vibration. The -30°C rating allows cold-start in unheated industrial environments, while the +70°C upper limit accommodates warm panel enclosures.
Is the LRS-75-48 suitable for global deployment with its AC input range?
Yes. The LRS-75-48 accepts 85–264VAC, covering 100V Japanese, 120V North American, and 230V European/international mains without hardware changes. Combined with its UL, CE, TÜV, CB, CCC, BSMI, RCM, and EAC certifications, it supports compliant global deployment.
