Appendix A Power Supply Specifications
6000 W AC-Input Power Supply
Remote Power Cycling Feature
The 6000 W AC-input power supply is equipped with a remote power cycling feature that allows you to
remotely turn on or turn off the power supply through an external relay controller box.
Figure A-9 shows
a typical remote power on/off setup. A three-position terminal block, located on the lower right quadrant
of the power supply faceplate, provides the interface to the external relay controller box. (See
Figure A-9.)

Terminal Block
The terminal block has four contacts labeled +V, IN, GND, and FB. Two control wires from an external
relay controller box attach to either +V and IN or IN and GND. +V and IN are used when the relay
controller box contains a normally-open (NO) type of relay. IN and GND are used when using an RS-232
interface.
