The wattmeters are housed in fully enclosed, portable half-size modular unit. Schematic diagrams and specifications are silk-screened onto the back of the front panel of each unit. The Three Phase Analog Wattmeters consist of two 300W meters wired together to measure the real power in three phase systems. Interconnections between components and connections are made through standard color coded safety sockets with banana plug jumper leads. Switches are provided to invert negative readings. Included in the Rotating Machines Trainer for 1/3 hp - 250 W.

The multi-tapped transformers give a choice of single and three-phase AC voltages for connectionto the diodes and thyristors. A centre-tapped inter phase transformer shows theeffect of reducing circulating currents in rectifier circuits. The control panel has clear mimic diagrams with shrouded sockets. Students use shrouded leads to connect the different parts of the circuits. The parts include thyristors, diodes, inductors, transformers and smoothingcapacitors. The Thyristor and Diode Trainer is a versatile teaching aid.It explores the principles and applications of thyristors, diodes andconverters. A mix of standard analogue meters and a multifunction digital metermeasure the currents and voltages in the circuits. Students use controls on the lower panel to adjust ACsupply voltage and ballast resistance during experiments. A load inductorshows the effect of inductance when smoothing the AC ripple in rectifiercircuits. Fast-blow fuses on the control panel protect the load side ofexperiment circuits.
Key Features:
Selectable gate pulse monitor connection to compare firingpulse with output waveforms
Fully equipped for both single and three phase experiments
Transducers and oscilloscope included for wave form monitoring
Internal or external thyristor firing control source
Variable thyristor firing delay for studies of harmonics andeffect of firing delay on output waveforms.
