a.c. Modular Servo System

Description

The a.c. system is used in more specialised and advanced control engineering courses where some detailed knowledge of a.c. carrier systems is required. It has the same basic form as the MS150 d.c. system and uses some common components. As a.c. systems are fundamentally more complex than d.c. systems, the theoretical work possible with the MS150A is to a higher level than that for the MS150 d.c. system. The MS150A will have particular relevance to control engineering for Military and Aviation schools and for universities and colleges catering for the aerospace and advanced electronic industries. As with the MS150, each unit is fitted with a magnetic base which holds the unit to the plastic coated steel baseplate, irrespective of the angle at which the baseplate is positioned. Individual units may be so arranged to create operating block schematic systems and interconnections between the units are made by jumper leads terminated in 4mm stackable plugs. The modular concept of the MS150 system permits the study of individual units and also, by combination, the investigation and performance testing of complete systems. A series of instructional manuals is supplied to provide comprehensive coverage of servo system theory and assignments.
