Kulon Mean Well LRS-350-36 36V 9.7A Power Supply - Compact 1U Design

In this review of the Kulon Mean Well LRS-350-36, the bottom line is simple: this is a compact, reliable 36V DC supply built for industrial and appliance use where space is tight and uptime matters. The reviewer found the unit useful for industrial automation and control applications because it combines a full 349.2W single output with a low 30mm height and strong protection features. If you need a high-efficiency, long-life switching supply that meets household appliance safety standards, this review shows why the LRS-350-36 deserves consideration.

Key Features

• Ultra compact 1U profile: The 30mm height and 215 x 115mm footprint save panel and enclosure space while still delivering full output power.
• High output power: Rated at 349.2W and 36V with up to 9.7A, it supplies stable power for automation machinery and electronic instruments.
• Robust protections: Built-in short circuit, overload, over temperature and over voltage protection helps safeguard connected equipment in industrial environments.
• Wide input range and surge tolerance: Universal AC input and the ability to withstand 300VAC surge for 5 seconds make it suitable for noisy or variable mains conditions.
• Built for heat and life: Free air convection cooling and operation up to 70C support long service life in demanding installations.
• Safety and traceability: Compliance to IEC/EN60335-1(PD3) and IEC/EN61558-1,-2-16 and verifiable serial numbers provide assurance for appliance and industrial use.

Who It's For

The LRS-350-36 is aimed at technicians, machine builders, and control engineers who need a reliable 36V DC source that packs near-350W output into a low-profile package for cabinets, control panels, and machinery where space is at a premium. Its protections and safety compliance make it a fit for appliance-related projects and industrial automation.

It is less suitable for hobbyists who need adjustable outputs or modular features, and users requiring fan-cooled high-current solutions for sustained heavy loads in poorly ventilated enclosures should consider a different model with explicit higher ambient derating or forced-air cooling.

Pros & Cons

Pros

• High power density in a 1U low-profile form factor, saving valuable panel space.
• Comprehensive protection suite reduces risk to downstream devices in fault conditions.
• Wide input tolerance and surge resistance suit industrial mains environments.
• Three-year warranty and serial number traceability for quality assurance.

Cons

• Passive cooling and compact size mean careful attention to ventilation is required at high ambient temperatures or near full load.
• No user-adjustable output features; fixed 36V single output limits flexibility in multi-voltage systems.
