The Magnaflux P-Series is an extremely compact, lightweight portable magnetizing unit designed for use in a wide range of magnetic particle inspection applications that require only moderate power to perform. Perfect for in-service inspections demanding maximum portability, the P-Series is built tough to take job-site abuse and offers many of the features and convenience of our larger units. The current control potentiometer of P-Series P-70 and P-1500 units provides infinitely variable magnetizing and demagnetizing current control. A power transformer, supported by fan cooled silicon diodes, transforms the high voltage, low amperage line input to low voltage, high amperage half-wave D.C. for magnetizing. Low voltage, high amperage A.C. is also provided for magnetizing and demagnetizing.
