Product Introduction

VIP1-1B-03 is a single-phase 3A EMI power filter with rated voltage of 115/250VAC and working frequency of 50/60Hz. It features ultra-low leakage current, and can work steadily within the temperature range from -25℃ to 100℃. This single-stage filter effectively suppresses common-mode and differential-mode electromagnetic interference on power lines. It has passed strict high voltage withstand and insulation resistance tests to deliver safe and reliable performance under various industrial working conditions.

Application & Purpose

This filter is widely used for PLC, servo drives, inverters and other industrial automation equipment. It is designed to filter high-frequency noise and power harmonics, prevent random misoperation or abnormal shutdown caused by power interference, and help finished equipment meet EMC standards to ensure continuous and stable operation of production systems.

FAQ

1. Q: What does RMS Max mean for the rated current of this filter A: RMS Max stands for maximum root mean square current. This parameter defines the continuous safe working current of the filter, and users should keep the operating current below this value to avoid magnetic core saturation.
2. Q: What is the function of the hi-pot test for EMI filters A: The hi-pot test checks the dielectric strength between wires and ground or between line and line. It verifies that the insulation material can withstand instantaneous overvoltage and prevent breakdown hazards during operation.
3. Q: Can this filter work normally at high temperature near 100℃ A: It can work within the temperature range of -25℃ to 100℃. However, long term operation at the upper temperature limit will accelerate component aging, so proper heat dissipation is recommended.
4. Q: What is the difference between line to ground and line to line hi-pot test A: Line to ground test applies voltage between power lines and the ground terminal, used to check insulation to earth. Line to line test applies voltage between live and neutral wires to verify insulation between internal power conductors.
