GLP Alimentatore switching DL2-150-48-U - 150W 48V DC guida DIN, PFC attivo, alta efficienza

Delivering 150W of stable 48V DC power with over 90% efficiency and active PFC, this GLP DIN rail power supply is built for industrial control systems, automation, and demanding electrical installations. The DL2-150-48-U accepts a wide 85-264 VAC input, ensuring reliable operation even in unstable grid conditions, and its convection cooling eliminates moving parts for silent, maintenance-free performance.

Overview

The GLP DL2-150-48-U is a compact, high-performance switching power supply designed for DIN rail mounting (TS-35/7.5 or TS-35/15). It provides an adjustable 48-55V DC output with a rated current of 3.125A, making it suitable for powering sensors, controllers, actuators, and other 48V industrial devices. The unit features active power factor correction (PFC) with a power factor greater than 0.95 at 230VAC, reducing harmonic distortion and improving energy efficiency. Comprehensive protection against overvoltage, overload, overtemperature, and short circuit ensures safe operation under fault conditions, while the rugged aluminum housing and wide operating temperature range (-20°C to +70°C) allow deployment in harsh environments.

What stands out

• High efficiency (>90%) and active PFC for lower energy costs and compliance with power quality standards.
• Wide input voltage range (85-264 VAC) and frequency range (47-63 Hz) for global compatibility.
• Adjustable output voltage (48-55V DC) to compensate for voltage drops or specific load requirements.
• Robust protection features including short circuit, overload, overvoltage, and overtemperature.
• Convection cooling for silent operation and high reliability (MTBF >700,000 hours).
• Compact DIN rail design for easy installation in control cabinets.
• Certified to UL 508, UL 60950-1, CE, RoHS, CB, and CCC for safety and environmental compliance.
