Description

Heavy-Duty EMI Power Protection for Industrial Systems

There are a great deal of electronic devices used in our lives, such as mobile phones, AV devices, personal computers, copy machines, and fax machines. These devices are seldom free from electric noise generation. Devices that insufficiently control noise can at times cause trouble or large social problems.

HAOZHUO PowerGuard HZ-4X70C5 is a high-performance emi power line filter designed for 380VAC, 70A applications. In environments with motors, inverters, and high-power equipment, EMI and RFI threats are rampant. This filter delivers up to 100dB insertion loss from 14kHz to 40GHz (MIL-STD-220A), suppressing both differential and common-mode noise, ensuring stable, interference-free operation.

Precision Electrical Specs for Safety and Performance

Key specs include full-rated current carrying capacity, forced overload handling at 140% of current for 15 minutes, and <1V voltage drop. With <2% harmonic distortion and leakage current ≤0.2A at nominal load, it meets MIL-STD-202, MIL-STD-220, and MIL-F-15733. Its dielectric strength (1kV line-to-line and to-case) and rugged terminal connections support demanding industrial usage.
