Lenze ELN3-0120H017 ELN3 Three-Phase Mains Choke

Description

Designed for power quality optimization in industrial drive systems, the Lenze ELN3-0120H017 three-phase mains choke reduces mains harmonics and limits commutation spikes. This line reactor acts as an inductive impedance in the mains supply line, protecting upstream frequency inverters and sensitive electronic components from transient overvoltages and grid disturbances. By smoothing the current waveform, the ELN3-0120H017 significantly reduces the RMS value of the mains current, lowering thermal load on cables and distribution equipment while improving the overall power factor of the system.

Features

• Reduces harmonic distortion (THDi) in compliance with international power quality standards.
• Limits mains current peaks and voltage spikes to protect inverter input rectifiers.
• Optimized for integration with Lenze frequency inverters and drive controllers.
• Three-phase design engineered for continuous industrial operation.
• Compact footprint allows for space-saving mounting inside control cabinets.

Applications

• Frequency inverter mains buffering in automated production lines.
• Industrial motor control centers and machine tool manufacturing.
• Pumping, ventilation, and air conditioning (HVAC) systems.
• Power quality improvement in weak or unstable electrical grids.

Installation Guidelines

• Mounting Position: Mount vertically on a flat, thermally conductive surface to ensure optimal natural convection and heat dissipation.
• Clearance: Maintain a minimum clearance of 50 mm above and below the unit to prevent thermal blockages.
• Grounding: Ensure a low-impedance PE connection directly to the control cabinet mounting plate.
• Cable Routing: Route input mains cables and output cables to the inverter separately to minimize electromagnetic interference (EMI).

Compliance and Certifications

• CE
• RoHS Compliant
