How to use

Before installation, confirm that the choke's electrical ratings (voltage and current) and physical dimensions match the system requirements. De-energize the circuit and follow safe isolation procedures. Mount the BDE 48 in the intended location ensuring secure mechanical fastening and appropriate clearance for heat dissipation. Make electrical connections according to the wiring diagram of the installation, observing correct polarity if applicable and using appropriate conductor sizes and insulation. After installation, perform functional checks and measure line conditions to verify that expected filtering and stabilization are achieved.

Usage recommendations

Use the inductor within the specified electrical limits and in environments free from excessive moisture or corrosive agents. For optimal performance, combine the choke with appropriate capacitive or resistive components as recommended by the system design and perform EMC tests after integration. If uncertain about compatibility or mounting, consult technical documentation or a qualified installer.
