Product Introduction

VIP1-1B-03 is a single-phase 3A EMI power filter rated for 115/250VAC at 50/60Hz. It features low leakage current and a wide operating temperature range of -25℃ to 100℃. This single-stage filter effectively suppresses both common-mode and differential-mode EMI noise on power lines. It passes strict high voltage and insulation resistance tests to ensure safe and consistent performance in industrial environments.

Application & Purpose

It is widely applied to PLC, servo drives, inverters and other industrial automation equipment. Its main purpose is to eliminate high frequency power interference and harmonics, prevent unexpected equipment malfunctions, and help products pass EMC compliance tests to keep the whole production system running stably.

FAQ

1. Q: What is the core function of VIP1-1B-03 power filter A: It suppresses common-mode and differential-mode EMI noise on AC power lines, protects sensitive industrial devices from power interference and helps equipment meet EMC requirements.
2. Q: Will installation affect the filtering performance of this filter A: Yes. Install the filter close to the power inlet. Separate input and output cables and keep good low-impedance grounding. Improper installation will greatly reduce noise suppression effect.
3. Q: What are common-mode noise and differential-mode noise A: Common-mode noise occurs between live or neutral wire and earth. Differential-mode noise exists between live wire and neutral wire. The filter uses inductors and capacitors to attenuate both types of interference.
4. Q: What is the recommended service life of this industrial power filter A: Under normal industrial operating conditions, it is suggested to replace the filter every 3 to 5 years. Regular insulation and grounding inspections can detect potential risks in advance.
5. Q: Can this filter be installed on the output side of an inverter A: It can be used on the inverter output side but the wiring length should be controlled within 30cm. Overlong wires will introduce extra parasitic inductance and weaken the filter s EMI suppression capacity.
