Power Supply H701A

This document is a technical schematic for a Power Supply (identified as H701A) designed by Digital Equipment Corporation. The diagram illustrates the electrical wiring for an Acme Electronic transformer (T-47688) connected to a Cinch Jones terminal strip. It includes a rectification circuit using diodes (D1-D4) and filtering capacitors (C2 and C3).

Key details provided in the schematic include:

• Voltage Configuration Table: A chart detailing the necessary jumper connections for various input voltages (ranging from 112.5V to 235V) to achieve the required output.
• Safety Instruction: A caution note advises users to check transformer taps before use.
• Component Specifications: Details for the capacitors (9,300 MFD/15V and 35,000 MFD/25V) and the resistor (25 ohms/25W).
• Administrative Info: The document is revision 3, dated January 22, 1965, and was drafted by H.W. Porter.
