What is this product?

The Mean Well LRS-350-48 is a compact, fanless industrial switching power supply that converts AC mains input into a steady 48V DC output at 350.4W. It's built for applications needing reliable mid-range power in a small, dust-tolerant enclosure.

Where is it used?

• LED lighting installations (indoor high-bay, signage, architectural lighting)
• Industrial automation panels driving 48V relays, contactors, and sensors
• CCTV and security system power backbones
• Small-scale CNC and machine tool control circuits
• Vending machines, kiosks, and embedded equipment power sections

Key technical advantages

The LRS-350-48 stands out for its fanless, free-air convection cooling design, which means zero moving parts, silent operation, and no fan failure risk — a major advantage in dusty Indian factory floors where fan-cooled units clog up and fail early. Its metal casing offers better EMI shielding and mechanical protection than plastic-cased alternatives, and the full-range auto-input voltage handles India's fluctuating grid supply without needing a separate voltage selector switch. Despite the compact size, it retains full protection circuitry (short circuit, overload, overvoltage) as standard, and its high 89% efficiency reduces heat buildup and running costs compared to older linear or lower-efficiency SMPS designs.

Why buy from Voltkart?

Voltkart is an authorized distributor and dealer for Mean Well in India, so the LRS-350-48 (EC-2681) you receive is guaranteed genuine with full manufacturer warranty — not a counterfeit or grey-market unit, which is unfortunately common with Mean Well products sourced from unauthorized sellers. Every order includes a proper GST invoice, PAN India delivery with fast dispatch from our Delhi (Bhagirath Palace) warehouse, and direct WhatsApp support (+91 98996 68881 / 8800754881) for bulk pricing, wiring guidance, or help choosing between fanless and fan-cooled Mean Well models for your specific panel.

FAQs

Q: Is the LRS-350-48 suitable for continuous 24/7 operation without a fan?
A: Yes, the LRS-350-48 is designed for continuous duty using free-air convection cooling, but proper enclosure ventilation and spacing around the unit are important to avoid heat buildup — we can advise on panel layout if you share your enclosure size.

Q: Can I mount the LRS-350-48 in any orientation?
A: Mean Well recommends mounting the LRS-350-48 horizontally (as per the datasheet orientation) for optimal natural convection cooling; mounting it sideways or upside down can reduce heat dissipation efficiency and shorten component life.

Q: What's the difference between the LRS-350-48 and LRS-600-48?
A: The LRS-350-48 delivers 350.4W at 7.3A, while the LRS-600-48 delivers 600W at 12.5A in a similarly compact metal casing — choose based on your actual load current; oversizing slightly gives you thermal headroom and longer component life.
