Description

The LRS-450 and 600 series adopt outward FAN cooling dissipation design. This design greatly improves the stability of the product. MEAN WELL has applied for a patent for the circuitry layout and appearance, and the product complies complete international safety regulations such as TUV/UL/CE/BIS and others. MEAN WELL persists in maintaining both quality and branding. In order to facilitate new design requirements of original customers, the LRS-450 and 600 series adopts the same size and pitch design as the SE-450 series and LRS-350 series, and high efficiency up to Max. 92%. In addition, the LRS-450/600 implement 3 seconds constant current limit for overload protection, and enhance greater flexibility when dealing with inductance and capacitance loads.

Key features

3-Second Constant Current Shutdown: When an overload spike hits (between 105% and 150% capacity), the unit maintains steady current for 3 full seconds rather than tripping instantly. This gives downstream equipment room to handle momentary startup in-rush currents before it gracefully shuts down. Ultra-Low-Profile 1U Form Factor: Standing at a strict 35 mm (1.37 inches) chassis height, it drops seamlessly into tight 1U server frames, slim industrial panels, and cramped test-bench arrays without restricting component layouts. Smart Fan Thermal Management: Features a built-in cooling system that utilizes smart thermal probes. The fan remains completely stationary and silent during standby or light loads, spinning up only when internal temperatures break 50°C and shutting down once it cools to 40°C.300VAC Input Surge Hardening: The internal transformer stage is ruggedized to safely absorb severe voltage swells up to 300V AC for 5 seconds. This prevents utility grid spikes from frying delicate low-voltage electronics on the output side.
