HTP25NP
PCB Mounting Hall Effect Current Transformer Type HTP25NP
The HTP25NP is a closed loop Hall Effect Current Transformer suitable for measuring currents up to 25A.
The product provides an output current, galvanically isol ated from the primary conductor into an external load
resistance. All contacts, including the primary are designed for PCB mounting.
