Product Description

VIP4‑2B‑10 (10307) is a single phase two stage EMI power filter for AC power line noise elimination. It supports rated voltage 115 250VAC and 50 60Hz power frequency with 10A RMS Max working current. Built with two stage filtering circuit it achieves great insertion loss for common mode and differential mode noise under 50 Ohm test system. It provides reliable high voltage withstand performance and high insulation resistance. Controlled leakage current and wide working temperature support stable operation in various working conditions. This filter can effectively suppress power line conducted electromagnetic interference and help end products meet EMC requirements.

Application Scope and Usage

This EMI filter is widely used for industrial automation equipment household appliances communication devices and other electronic control products. It is installed at the power input terminal of equipment. Its core purpose is to filter electromagnetic noise from power grid and noise generated by equipment itself. It reduces interference between different electronic units improves equipment operating stability and assists finished products to pass EMC certification tests.

FAQ

1.What is the core function of EMI power filter The core function of EMI power filter is to suppress conducted electromagnetic interference on AC power lines. It handles both common mode noise and differential mode noise. It blocks noise from power grid entering equipment and prevents noise generated by equipment from feeding back to power grid. It improves anti interference capacity of whole system and supports end product EMC certification.

shtur to select suitable current rating for EMI filter Select filter rated current according to maximum actual working current of your device. The filter rated current should be equal to or higher than device maximum working current. Long time overload will cause filter overheat performance drop and shorten service life. Excessive current margin will also bring unnecessary cost waste.

3.Why leakage current value differs among different filter models Leakage current is mainly determined by internal Y capacitor and working voltage. Higher working voltage brings larger leakage current. Different models adopt different capacitor schemes. If your project requires low leakage current please choose corresponding low leakage version. Do not modify internal components of finished filter.

4.What causes unsatisfactory filtering effect after filter installation Poor filtering effect mostly comes from non standard installation. Long or intertwined input and output wires will produce noise coupling. Input and output cables shall keep proper separation distance. Solid and reliable ground connection is essential. Filter shell should closely contact with metal chassis to get ideal noise suppression result.

5.What points should we notice for filter daily use Do not operate filter beyond its rated voltage rated current and temperature range. Avoid humid dusty or corrosive environment. Check grounding condition regularly. Damaged filter shall be replaced in time. Do not disassemble filter housing arbitrarily which will destroy internal circuit and safety structure.
