Mobile Power Packs

The MAG 50 HM mobile power packs offer a convenient solution to in-field testing. Designed to be taken to the component for inspection, the MAG 50 HM series is ideal for performing magnetic particle inspection of in-field parts or large heavy parts that require only moderate power.

These power packs have a constant current system that eliminates the guesswork of controlling current by means of conventional tap switches or variable transformers. The precise amount of desired current is delivered to the output circuit when the magnetising shot is initiated. The self-regulating current circuitry and solid state controls automatically compensate for variation in load impedance, such as heating or varying cable lengths. As a result, every current control setting delivers the exact amount of current indicated up to the maximum output for a particular load.
