Frequently Asked Questions
What industrial or automation applications are appropriate for the LRS-350-48?
The LRS-350-48 provides 48V at 7.3A (350.4W), a common bus voltage for PoE infrastructure, brushless DC motor drives, telecommunications equipment, and industrial Ethernet switches. Its 1U profile and 215 × 115 × 30 mm footprint allow rack or DIN-rail panel integration.
How does the LRS-350-48 compare to the LRS-350N2-48?
Both models output 48V at 7.3A (350.4W) and share identical dimensions (215 × 115 × 30 mm) and weight (0.76 kg). The LRS-350N2-48 adds 200% peak power capability for handling transient motor or load surge currents, while the LRS-350-48 does not offer this peak power feature. Both carry CB, CE, CQC, EAC, TÜV, and UL certifications.
What is the operating temperature range of the LRS-350-48?
The LRS-350-48 operates from -25°C to +70°C. This range covers most industrial indoor environments and allows full-rated operation in enclosures that can reach 70°C ambient without derating.
Is the LRS-350-48 appropriate for 48V DC bus systems in telecom cabinets?
The LRS-350-48 outputs a 48V constant-voltage rail at up to 7.3A, suitable for powering 48V DC bus loads in telecom or IT equipment racks. Its UL and CE certifications support deployment in regulated environments, and the universal 90–264VAC input covers both 120V and 230V supply systems.
Does the LRS-350-48 require derating at high ambient temperatures?
The LRS-350-48 is rated for full 350.4W output up to 70°C ambient. No derating information beyond that upper limit is specified in the product data; operation beyond 70°C is outside the rated range.
