Meanwell 12V 37.5A Switch mode P/Supply
Meanwell 12V 37.5A Switch mode P/Supply
Overview
An industrial-grade, enclosed AC-to-DC utility converter providing a fixed 12V DC output up to a maximum continuous current of 37.5 Amps. This yields a total power rating of 450 Watts.
Specifications
Output Voltage12V DC (Adjustable via onboard potentiometer). Rated Current0 to 37.5 Amps continuous load capacity. Total Power Output450 Watts maximum delivery. Input Voltage Range90–132 VAC / 180–264 VAC (Selectable by toggle switch). Input Frequency47 Hz to 63 Hz standard utility grid. Cooling Profile Forced-air cooling via built-in DC exhaust fan
Key features
3 Seconds Constant Current Limit: Unlike lower-tier power supplies that instantly shut down under high inductive or capacitive in-rush spikes, the modern Mean Well LRS-450 framework maintains constant current for 3 full seconds during overload conditions to prevent circuit choking. Intelligent Thermal Management: Features a built-in cooling fan with an integrated automatic ON-OFF control sensor. The fan remains completely silent and idle during low-current operation, engaging only when internal components reach heat thresholds.. Ultra-Low 1U Profile Layout: Enclosed in a strict 35mm thick, low-profile chassis, maximizing vertical density inside slim electronics racks or low-clearance test benches. Built-In Voltage Regulation Potentiometer: Positioned directly next to the output terminals is an adjustable onboard screw potentiometer (+V ADJ), allowing users to manually dial the baseline voltage from roughly 10.8V up to 13.5V to compensate for line loss over long cable runs.
