Dual Motor Voltage Control 6847

This document is a technical schematic for a Dual Motor Voltage Control circuit designed by Digital Equipment Corporation in 1969. The circuit provides two regulated output channels (E1 OUT and E2 OUT) derived from a +45V input source, with a secondary +15V rail. Each channel utilizes a configuration of transistors (2N3715, MPSA05) and diodes (IN5624, D672) to manage power distribution. The diagram includes specific component values for resistors and fuses (5 Amp), along with a transistor and diode conversion chart to assist with maintenance and parts replacement.
