VIIP VIP4-1B-20 Single Phase EMI Power Filter: Perfect EMC Solution for Desktop & Industrial 3D Printers

Why 3D Printers Suffer Poor Precision Without EMI Filter

• Conducted & radiated noise disturbs motherboard control signals, causing layer lines, model warpage, dimensional deviation
• Stepper motor jitter leads to blurry tiny details, filament drawing and high reject rate
• Long-term EMI accelerates aging of mainboard, hot end and drive components
• Grid surge fluctuation results in unstable nozzle temperature and frequent printing failure
  All these issues waste printing materials, labor time and increase production costs greatly.

Core Advantages of VIIP VIP4-1B-20 EMI Filter 

1. High-current single-stage filter with built-in discharge resistor, dual Cx & Cy capacitor circuit, stronger suppression for both common-mode & differential-mode noise
2. Excellent wideband insertion loss (50Ω test system): 30dB CM attenuation @1MHz, max 53dB CM @10MHz, 60dB DM @5MHz
3. Compact metal housing dimension 29*51.5mm, small footprint, easy panel mounting for limited inner space of 3D printers
4. Full 20A RMS rated current under 115VAC / 250VAC, support heavy-load industrial printing equipment
5. Ultra-low leakage current: ≤0.3mA@115VAC/60Hz, ≤0.6mA@250VAC/50Hz, safe for electronic control boards
6. Strict safety Hi-pot standard: 2000VAC line-to-ground, 1450VDC line-to-line for 1 minute; insulation resistance ≥100MΩ@500VDC
7. Wide temperature working range: -25℃ ~ +100℃, stable performance in factory workshop & home studio environment
8. Complete global certifications: cULus, CE, RoHS, REACH, fully compliant with EU & North America export standards
9. Stable long service life, low heat generation, no extra thermal burden for printing devices
