Enclosed Type 350.4W 24V 14.6A LRS-350-24 - Compact Switching Power

Our review of the Enclosed Type 350.4W 24V 14.6A LRS-350-24 finds it best suited to technicians and system builders who need a reliable, compact AC-DC supply with household safety approvals. The single biggest reason to buy is its combination of high output in a low 1U profile and broad safety certifications, which makes it a practical choice for embedded equipment, appliance interfaces, and small server or UPS applications where space and compliance matter.

Key Features

• High output in small size: Delivers 350.4W at 24V in an ultra compact, 1U low profile enclosure that fits tight rack or chassis spaces.
• Low no-load power: No load power consumption is very low (0.2W to 0.75W) to reduce standby energy use in always-on installations.
• Household appliance safety: Complies with IEC/EN60335-1(PD3) and IEC/EN61558-1,-2-16 making it suitable where appliance-level approvals are required.
• Convection cooling: Cooling by free air convection for 150W and 200W variants means quieter operation and fewer moving parts in many setups.
• Wide environmental tolerance: Rated for 5G vibration and operation at altitudes up to 5000 meters, useful for industrial or field deployments.

Who It's For

This unit is aimed at engineers, service technicians, and small system integrators who need a compact, certified power supply for appliances, control cabinets, or compact servers. Its emphasis on safety approvals and low standby consumption makes it appealing in household appliance interfaces and equipment where regulations matter.

Buyers who need active PFC, fan-cooled high-density power in extreme ambient heat, or integrated battery management should look elsewhere; the LRS-350-24 is a non-PFC, convection-focused design optimized for efficiency and compactness rather than maximum power factor correction or custom battery features.

Pros & Cons

Pros

• Compact 1U form factor provides high power density for tight installations.
• Very low no-load power consumption helps reduce standby energy draw.
• Multiple safety certifications give confidence for household appliance and equipment use.
• Convection cooling reduces noise and moving part failures in many applications.

Cons

• Non-PFC design means it is not optimized for power factor correction in installations that require it.
• Convection cooling may limit sustained thermal headroom in very hot, enclosed environments compared with fan-cooled models.

Our Verdict

The Enclosed Type LRS-350-24 is an excellent value for anyone who needs a certified, compact 24V switching supply with low standby draw and reliable convection cooling. It is best for appliance-grade equipment, compact racks, and integrators who prioritize safety approvals and form factor; choose a fan-cooled or PFC-equipped alternative only if your design specifically requires those features.

Frequently Asked Questions
