Frequently Asked Questions
What 5V applications is the LRS-75-5 suited for at 14A?
At 5V and 14A (70W), the LRS-75-5 can power multi-board embedded systems, backplanes with several SBCs or microcontroller modules, 5V LED indicator arrays, and industrial HMI panels with combined 5V load demand up to 14A. Its 99 × 97 × 30 mm footprint suits compact control cabinets.
How does the LRS-75-5 compare to the LRS-50-5 and LRS-100-5?
All accept 85–264VAC. The LRS-50-5 (99 × 82 × 30 mm, 0.21 kg) outputs 50W at 10A. The LRS-75-5 (99 × 97 × 30 mm, 0.23 kg) outputs 70W at 14A. The LRS-100-5 outputs 80W at 18A. The LRS-75-5 provides the mid-tier 5V current capacity for systems where 10A is insufficient but 18A is more than needed.
Does the LRS-75-5 rated power of 70W differ from other LRS-75 voltage variants?
Yes. Unlike most LRS-75 models that achieve approximately 72–76.8W, the LRS-75-5 delivers 70W (5V × 14A). This slight difference is inherent to the voltage/current combination at the 5V output level and is within the normal variation of the LRS-75 family across voltage options.
What is the operating temperature range of the LRS-75-5?
The LRS-75-5 is rated for -30°C to +70°C operation with 5G vibration resistance. The -30°C lower limit allows cold-start in unheated industrial or cold-storage environments, and the +70°C upper limit accommodates the thermal conditions found in warm industrial control cabinets.
Does the LRS-75-5 hold the certifications needed for commercial building control systems?
The LRS-75-5 carries BSMI, CB, CCC, CE, EAC, RCM, TÜV, and UL certifications. UL listing and CE marking satisfy the primary safety and regulatory requirements for North American and European commercial building installations and equipment.
