VIP1-1B-03 is a single-phase 3A EMI power filter with rated voltage of 115/250VAC and 50/60Hz operating frequency. It is designed with ultra-low leakage current, with maximum leakage current of only 2uA at 115VAC/60Hz and 5uA at 250VAC/50Hz. This single-stage filter can work reliably within a wide temperature range of -25℃ to 100℃. It has passed strict 2000VAC line-to-ground hi-pot test and features insulation resistance over 100M ohm at 500VDC, effectively suppressing common-mode and differential-mode electromagnetic interference on power lines for safe and stable operation.

This EMI power filter is widely used in PLC, servo drives, inverters and various industrial automation equipment. Its core purpose is to filter high-frequency electromagnetic noise and power harmonics on AC power lines. It prevents equipment misoperation and abnormal shutdown triggered by power interference, helps finished products pass EMC compliance tests, and ensures stable and continuous operation of automated production systems.

1. Q: What is insertion loss of an EMI power filter A: Insertion loss represents the noise attenuation capability of the filter, measured in decibels. Higher insertion loss means better performance to block high frequency electromagnetic noise in the power circuit.
2. Q: What is the advantage of ultra low leakage current for this filter A: Ultra low leakage current meets strict safety standards. It is especially suitable for equipment requiring high grounding safety and low residual current.
3. Q: What is the function of the internal fuse in VIP1-1B-03 A: The built-in fuse provides overcurrent protection. It will blow automatically when overload occurs to protect the filter and backend equipment from damage caused by short circuit or excessive current.
4. Q: What is the meaning of insulation resistance for power filter A: Insulation resistance reflects the insulation performance between power terminals and ground. High insulation resistance above 100M ohm prevents current leakage and insulation breakdown under normal working voltage.
5. Q: Can this filter be used in high temperature industrial cabinet A: It supports working temperature from -25℃ to 100℃. It can be installed inside equipment cabinets, but proper heat dissipation is required and avoid long term continuous operation at the maximum temperature limit.
