Product Description

The LRS-450-12 Power Supply is a rugged 450W 12V DC industrial PSU designed for demanding environments, delivering stable 12V DC output with a maximum current of 37.5A. It accepts a universal AC input voltage range of 85-264V AC and operates efficiently within -20°C to +70°C, ensuring reliability in industrial automation, telecommunications, and machinery systems. This compact switching power unit supports parallel expansion for higher power requirements and integrates protection against overload, over-voltage, and short circuits. It features a metal enclosure for enhanced durability and includes terminal block connections for easy wiring. While optimized for high efficiency (up to 90%), it lacks modular scalability and requires external cooling in high-temperature applications. Critical for systems demanding consistent low-voltage power with minimal ripple noise.
