AC / DC Electrical Training System

AC / DC Electrical Training  System .
This unit shall include: one (1) base unit with (1) power supply on/off selector switch, indicator lamp, AC-DC selector switch and indicator lamps, circuit breaker, output terminals for connection to devices, component work surface and instrument console with component storage panel.  Voltages available shall be 24 volts and 12 volts, AC and DC, which is controlled by the AC-DC selector switch.  These components shall meet the below minimum
specifications.AC/DC Electrical Systems Trainer
One (1) Analog voltmeter shall be built into the instrument console with terminals so that test leads can be connected for making measurements.  Range of the scale is from 0-30 volts, AC or DC.  The component storage panel shall allow storage and identification of loose components that are included with trainer. The component work surface shall be a flat surface 20”x17” located on top of the worktable and in front of the instrument console where components can be quickly attached and circuits setup. All loose components shall be mounted on mobile plastic panels with all component leads attached to metal spade-lug terminals which have thumbscrew attachment spade-lugs, requiring no tools.  The loose component panels shall use a quick connect mounting /release method which permits the component circuits to be set up on the work surface and storage panel. The components shall include:
