Industrial DIN Power Supply
NV-PW240-48
Industrial DIN-Rail Power Supply (240W, 48V-57V) – NV-PW240-48 Key Features: • Optimized for industrial network devices with a continuous 48V-57V DC output. • High power output of 240W, dedicated to powering heavily loaded PoE switches. • Convenient and universal mounting on a standard industrial DIN rail. • Comprehensive protection system: short-circuit, overload, over-voltage, and over-temperature. The NV-PW240-48 industrial power supply is the absolute heart of a stable and secure infrastructure. Specifically constructed for integration into control cabinets on a DIN rail, it delivers the clean and reliable voltage required by industrial network switches and PoE-powered equipment. With a high power budget of 240W, this power supply can easily support an entire matrix of receiving devices, such as high power-consumption professional CCTV cameras (including PTZ models). The solid metal casing provides fanless heat dissipation, ensuring quiet, continuous, and 100% trouble-free operation, even in extremely harsh environmental conditions.
