Power Supplies Types 783, 783A

Summary This document provides specifications for the Type 783 and 783A power supplies, which are designed for mounting in standard 19-inch racks. These rugged units provide dual outputs (+10V and -15V DC). The document details electrical characteristics, including input/output voltage and current limits, regulation, ripple, and frequency tolerance, as well as mechanical dimensions and connection types. A specific formula is provided to calculate the output current limitations when both channels are loaded simultaneously. The Type 783A model differs from the 783 by including a 50-cps transformer.
