TR-7 and TR-5 Power Supply

The PS-75 is a high current, 13.6 VDC power supply for use with solid state transceivers in CW or SSB modes. The supply operates from a primary voltage of 100, 120,200 or 240 VAC, 50-60 Hz (switch programmed), and provides 15 amperes continuous at an unregulated voltage of 13.6 VDC (nominal) for use with solid state power amplifiers and a 3 ampere regulated out-put for use with the remainder of the transceiver. In addition, a regulated 13.6 VDC at 1 ampere is provided for auxiliary equipment. The supply was designed primarily for SSB operation at current levels of 15 amperes average and 25 amperes peak but Will also provide reliable performance on CW at current levels of up to 25 amperes. Some CW signal quality degradation due to the increased ripple may be noticed at CW power levels which exceed 15 amperes current drain (usually about 75 watts).
