Lambda / TDK / EMI LS-513

The Lambda/TDK EMI LS-513 is an EMI filter and power supply unit engineered for industrial and electronic applications requiring stable, reliable power delivery with superior noise rejection. The unit minimizes electromagnetic interference through high-quality filtering architecture, delivering clean power to sensitive equipment while maintaining tight output regulation across the entire input line voltage range.

Technical Specifications

• Input Voltage: Single-phase 85–265 VAC (47–63 Hz) or 100–240 VAC (50–60 Hz)


• Output Voltage Range: 1.2 V to 62 VDC (select series); up to 600 V or 1000 ADC on other configurations


• Load Regulation: Less than 0.1% of maximum rated output across full input line voltage range


• Output Voltage Deviation: Less than 0.1% of maximum output voltage on 100% load change (full load to no load)


• Efficiency: Up to 90% on high-power density models; minimum 83% at low AC line and 100% rated load


• Inrush Current: Limited via power thermistors or soft-start mechanisms; less than 0.2 ms under cold start at 25°C


• Power Factor Correction: Active PFC available for single-phase and three-phase AC inputs on select models

Key Features
