MPI Power Packs


Portable Current Generator

Mobile MPI Power Pack

The Tri-Ad is a portable power pack with variable AC and DC output and is ideal for performing pistol prod and encircling techniques - Due to the variable supply the Tri-Ad can be used for demagnetising too. The Tri-Ad can also be used in conjunction with fixed coils, split coils and ‘G’ clamp type prods. All cables use quick release DINSE connectors for increased inspection efficiency and the Tri-Ad is supplied fully calibrated and with the relevant paperwork. Energising foot pedals available.

Safety features such as a circuit breakers and a series of fuses are fitted as standard on the Tri-Mag 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.
