Product Positioning

Single phase high-power equipment inlet EMI filtering is used to suppress the conducted interference generated by switching power supplies, servos, and high-power inverters, while also resisting grid noise. It is used for complete machines that need to meet CE/UL EMC testing requirements; Bidirectional input and output are available (LINE/LOAD without directional mandatory requirements)

Main application scenarios

1. High power industrial automation (most typical)

High power servo/multi axis servo control cabinet, high-power single-phase frequency converter (220V single-phase high-power drive)

Industrial complete machine control cabinet, automation production line control box, robot electrical control cabinet

Front end of high-power single-phase switching power supply (5kW level 220VAC power supply)

The 30A specification is suitable for equipment with 220V single-phase input and a maximum load power of about 6-7kW

2. Testing, Measurement, and Semiconductor Equipment

High power testing instruments, power testing systems, aging testing benches

Semiconductor process equipment, plasma cleaning, laser processing equipment (internal high-frequency noise is extremely strong, and conducted EMC is prone to exceeding the standard)

3. Communication and high-power security equipment

Communication high-power single-phase power supply unit, base station supporting high-power AC-DC power supply

Large security host, high-power charging pile auxiliary control power supply (single-phase input side)

4. Medical equipment (standard leakage current version)

High power medical diagnostic equipment, CT auxiliary power supply, large inspection and analysis instruments

Key points for design and usage

1. Installation: Close to the AC inlet of the equipment, the metal casing of the filter is reliably connected to the metal casing of the equipment over a large area, and grounding is the key to EMC; The ground wire from the filter to the casing should be short and thick.

2. Derating: Rated at 30A, for high temperature environments (>45 ℃) that require derating, a current margin of at least 20% should be reserved for selection.

3. Leakage current limit: Maximum 1mA. When multiple filters are connected in parallel, the total leakage current is superimposed, and the risk of misoperation of the leakage protection switch needs to be considered.

4. Wiring: Separate the input and output cables and do not bundle them together to avoid noise coupling and feedback.

5. Short circuit withstand SCCR=5kA, the front end must be equipped with suitable fuses for short circuit protection.
