System Module Accessories Feb64

This document is a catalog, copyrighted in 1964 by Digital Equipment Corporation (DEC), detailing "New Module Accessories" for their digital systems. It primarily covers three categories of products: Power Supplies, Mounting Panels, and Indicator Lights.

Key offerings include:

1. Power Supplies: A range of standard power supplies (e.g., Types 782, 783, 710, 722, 743) designed for various system sizes and applications (small, medium, large, laboratory). They offer common outputs like +10V and -15V DC, feature short-circuit protection, and efficient regulation. The catalog also lists adapter brackets (Type 784) and a Power Control Panel (Type 831) with a 2-pole circuit breaker.
2. Mounting Panels: Two main types are featured: the Type 1935 Mounting Panel and the Type 1938 Power Supply and Mounting Panel (which integrates a power supply). These 19-inch rack-mountable panels are highly customizable, offering various connector types (forked-pin solder, wire-wrap, taper pin), endplate setbacks, power connection options (terminal block, marginal check switches), and features like heavy-duty sockets, lettered contacts, and improved ventilation for accommodating DEC System Modules.
3. Indicator Lights: A selection of indicator units (Types 4901, 4902, 4903, 4906, 4908) from single panel-mountable lamps to brackets with multiple (7, 9, or 18) indicators. Some models include integrated transistor amplifiers, while others are lamp assemblies requiring external drivers. They typically operate on -15 volts and utilize under-volted 28V bulbs for extended life.

The document provides detailed electrical and mechanical characteristics, including output voltages, currents, regulation, physical dimensions, and connection types for each product. Pricing is listed, with notes on effective dates (e.g., April 1, 1964) and options for 50-cycle versions. Ordering information and diagrams are also included.
