Overview
The Schaffner FN5420-145-99-E0XXT is a three-phase sine wave output filter designed for variable frequency drive applications. It operates at a rated voltage of 500 VAC and supports a current capacity of 145 A. The unit features an IP00 protection rating, allowing for floor mounting in controlled environments. It ensures sinusoidal current and voltage with less than 5% ripple, protecting motors from high dv/dt stresses.
Feature Summary
- Generates sinusoidal output waveforms to protect motor insulation
- Reduces voltage ripple to below five percent
- Supports floor mounting configurations
- Designed for industrial variable frequency drive systems
Applications
- Variable frequency drive output filtering
- Motor protection against high dv/dt stress
- Industrial automation drive systems
Procurement Notes
Verify the complete part number including suffixes to ensure correct current and voltage ratings. Confirm installation requirements such as floor mounting space and ventilation needs. Check for specific certification requirements relevant to your region. Ensure compatibility with the drive system's output characteristics before procurement.
Selection Notes
Select this model based on the required 145 A current rating and 500 VAC operating voltage. Consider the IP00 rating when determining enclosure requirements. Evaluate the need for sine wave filtration versus standard dv/dt filters based on motor sensitivity and cable length.
Part Context
This component belongs to the Schaffner FN5420 series of sine wave filters. These units are engineered to convert PWM drive outputs into near-sinusoidal waveforms. The series is widely used in heavy industry to extend motor life and reduce electromagnetic interference.
Replacement Considerations
FN5420-180-99-E0XXT offers higher current capacity. FN5420-60-92-E0XXT provides lower current handling. Verify mechanical dimensions and terminal configurations when substituting.
