Technical Specifications: 
The BG902S Case contains: 
0-25 VDC Power Supply, up to 500mA
0-25/100 VDC Power Supply, up to 50mA
6 VAC and 12 VAC Power Supplies
DC Voltmeter for 25 VDC
DC Voltmeter for 25/100 VDC

Assortment of resistors, capacitors, inductor coil, transformer, relay, solarcell, diodes, switches, lamps, potentiometers, thermistor, transistors-NPN and PNP, FET, UJT, PUT, SCR, OP AMP module, Universal Module and interconnecting leads, etc. Two etched aluminum storage trays and a foamlined compartment to store all of the experimental parts and leads. The overall size of the unit is 17"W x 13"D x 16"H. It requires a power source of 1 1 5 VAC, 50/60 Hz. Also available for 220 VAC.

Features:
The unit is complete with three lab manual/texts that have proven to be an excellent basis for a course of study up to 300 hours, and is easily mastered by beginning and intermediate students. All of the AC and DC self-contained power supplies are current limited and over-load protected. The integral voltmeters measure the output of the two DC power supplies at all times. All of the meters and power supplies are mounted on a two-color etched 1/8" thick aluminum panel. All mate rials and the power/meter unit are housed in a sturdy formica-covered wood case with a locking front cover. Two separate modules are included for advanced study: OP AMP Module and Universal Module. They allow the more advanced circuits to be assembled quickly and easily.
