The VIIP VIP3-32B-20 is a high-performance EMI/RFI filter designed for three-phase AC power lines. It employs a dual-stage configuration to effectively suppress conducted electromagnetic interference within industrial power systems. This filter operates efficiently with voltages up to 380/480 VAC at frequencies of 50/60 Hz and supports a rated current of 20A RMS.

Featuring a two-stage LC filtering network, the VIP3-32B-20 delivers exceptional attenuation of both common-mode and differential-mode noise. It effectively covers a frequency range from 150 kHz to 30 MHz, ensuring optimal noise reduction across a wide spectrum.

The device is enclosed in a durable, fully shielded metal housing that offers robust protection. It includes touch-safe industrial screw terminal blocks for secure and safe connections. This design guarantees reliable compliance with international electromagnetic compatibility (EMC) standards such as CISPR 11/EN 55011, CISPR 32/EN 55032, and IEC/EN 61800-3.

The model number for this product is VIP3-32B-20 . It is designed as a three-phase dual-stage EMI power line filter.

The device operates at a rated voltage of 380 VAC or 480 VAC and can handle a maximum rated current of 20A RMS at these voltage levels. It supports an operating frequency of 50 to 60 Hz .

Regarding leakage current, it maintains a maximum leakage current of 5.0 mA per line to ground when operating at 480 VAC and 60 Hz. For safety testing, the Hi-pot test voltage is set at 2000 VAC from line to ground, and 500 VDC from line to line, each applied for one minute.

The insulation resistance is specified to be at least 100 MΩ when measured at 500 VDC between any input or output terminal and ground.
