Tektronix PS 503A provides dual floating variable 20V supplies, plus a fixed 5-V, 1_A supply. The PS 503A features superior tracking, over voltage protection, and remote resistance programing of voltage. When operated in the high power compartment of a TM 504, TM506, or TM5006 mainframe, the PS503A can provide up to 1 A from both of the 20V supplies. A 0 to 40V variable supply with up to 1 A of current can be configured by grounding one of the two outside terminals of the variable supplies. The two variable supplies can be set individually, then varied in a tracking mode with a signal control. In addition, the plus and minus floating outputs can be programed remotely, by either voltage programing or resistance programing via the rear interface.
