MPI Power Packs

Tri-Ad

Portable Current Generator

2000A Mobile MPI Power Pack

The Tri-Ad is a portable power pack capable of variable AC outputs which can be used for performing pistol prod and encircling techniques as well demagnetizing components.

Johnson & Allen can supply a range of accessories with the Tri-Ad including encircling cables, pistol prods, ‘G’ clamp prods, split coils and foot switches. All cables use quick release DINSE connectors for increased inspection efficiency.

Ideal for finding surface and near surface defects

The Tri-Ad is ideal for finding surface and near surface defects in large or heavy parts, in-service components or weld testing on-site. Supplied calibrated and with the relevant paperwork.

Safety features such as a circuit breakers and a series of fuses are fitted as standard on the Tri-Ad to ensure that even inadvertent misuse will not put operators at risk. Johnson & Allen pride itself on high quality design and construction which is why the power transformers used in the Tri-Ad are wound, built and extensively tested in house before they are installed.
