PURPOSE:To enable installation of a high voltage and large amperage output module by being provided by an electric power supply means for a V1 module independently from the V1 module which is inserted into and installed to a slot of a VME bus and generates the predetermined voltage and amperage by controlling the V1 module. CONSTITUTION:A plurality of V1 modules 2 are installed to slots of a main frame 1 and an electric power supply unit 3 is prepared independently. To the unit 3, commercial electric power is supplied from a service plug receptacle of a main frame 2, and the unit 3 is connected to the module 2 by a cable. The unit 3 has an automatic switching device of output voltage for constant electric power output operation. That is to say, very stable DC electric power is produced in the unit 3 from the commercial electric power, and high voltage electric power + or -V1, + or -V2 and + or -V3 to actuate a circuit of the module 2, is supplied to the module 2 from the unit 3. In this way, high voltage and large amperage DC electric power can generated and also the VME system can be systemized without losing controlling speed thereof. |
