Speciality Magnetic Components QUALIFIED to ISO STANDARD PCB Mounting Hall Effect Current Transformer Type HTP50NPV The HTP50NPV is a compact, multiple primary turn closed loop Hall Effect Current Transformer suitable for measuring currents up to 50A. It is designed for those applications where connection to the primary circuit is made directly on the printed circuit board. The product provides an output current, galvanically isolated from the primary conductor into an external load resistance. All contacts, including the primary are designed for PCB mounting.
