LFS Series Low Noise AC/DC Supply (10mV@50W,10-13mV@150W)

LFS Series Low Noise AC/DC Power Supplies

The LFS Series includes the LFS50A and LFS150A models of low-noise switching power supplies designed for noise-sensitive applications. Their compact, lightweight design maximizes efficiency and provides high reliability, while the low ripple, low EMI, and very low leakage current (≤0.15mA at 264Vac) make them ideal replacements for linear power supplies. LFS Series power supplies are often used in medical, biotech, testing, and measurement environments.

Key Features of the LFS Series

• Compliant with IEC 60601-1 medical safety standards
• Ultra-low ripple and noise
• Very low leakage current (≤0.15mA at 264Vac)
• Low conducted and radiated emissions
• Wide input voltage range (85–264Vac)
• Convection cooling
• Remote sensing, remote on/off control, and remote voltage adjustment
• LED operation indicator
• EMC & immunity compliant (EN55022-B, FCC-B, VCCI-B, EN61000 series)
• Certified to UL62368-1, EN60601-1, CE, PSE

Differences Between the LFS50A and the LFS150A Low Noise Power Supplies

LFS50A Series

The LFS50A series offers a range of compact low-noise power solutions with a maximum output power of up to 52.8W. These units are ideal for applications requiring a smaller footprint while maintaining excellent performance.

LFS150A Series

The LFS150A series provides a higher power output of up to 153.6W while still maintaining the ultra-low noise characteristics of the LFS family. These models are designed for more demanding applications that require higher power delivery.
