Our power packs are for supplying the high currents required for magnetic particle inspection equipment.

Up to 20,000 Amps peak AC, HWDC, FWDC and 3-Phase FWDC or combined outputs

Fast & efficient low frequency demagnetising

Infinitely variable, self regulating output

Large LED meter with full setup display

Optional stepped current selection for pure sinusoidal magnetizing waveform

Our range of mobile magnetic particle inspection power packs provide the high current necessary for magnetic particle inspection of large components or structures that cannot be moved, or for use with existing bench units.

The power pack comprises a regulated, power transformer together with rectifiers and control system all housed in a steel cabinet mounted on four wheels, two of which are braked. The high amperage output is applied to the piece under test via large cross section copper bus bars and flexible cables for current flow or encircling coil magnetising.

The high current output produced allows fewer magnetising operations on large or long components, and is automatically controlled to the desired output level set (within operating limits). If the required output current is not achieved due to poor contact or excessive loads, a warning system is invoked to ensure the operators awareness.

Demagnetising is achieved using reducing amplitude low frequency, approx 16 2/3 Hz, AC current. The demagnetising output automatically begins at 10% above the magnetising value to ensure efficient demagnetising.

Output current is regulated by fast solid state devices which allow self regulation of the desired output. For the purest output the current may be regulated by use of a stepped transformer although this cannot be self regulated to automatically control the output to the desired level.

Control of the power pack is through the screen dialogue and simple rotary control and "ENTER" button. The active unit settings are displayed on the screen which also incorporates a large digital ammeter with reading hold facility.
