AutomationDirect’s AEGIS powerline filters/surge protectors are designed to protect single-phase electrical and electronic equipment from surges and line noise that can cause misoperation and damage. With multiple levels of surge protection, AEGIS series units guard against surges and clean up line noise. Available in premium filter and premium hybrid models, the powerline filters react instantly to changes in voltage regardless of phase angle or polarity; the premium hybrid model is ideal when the highest level of RFI/EMI protection is required, the company explains. AEGIS powerline filters are 35-mm DIN rail-mountable and feature LED status indicators; premium hybrid models also feature alarm contacts. The compact design contains no replaceable parts or items that require periodic maintenance. Available models provide up to 75 dB of filtering and up to 60 kA of surge protection. All units meet the latest UL safety standards for SPD (surge protective device) and EMI filtering protection.
