About this file
This is a product specification and technical data sheet for AAC American Aerospace Controls Inc.'s Series 205 DC Ammeter Shunt. The document details a line of DC ammeter shunts designed to measure electrical current in high-amperage applications, with measuring ranges from 2,500A to 10,000A and output ranges of 50mV and 100mV. The shunts are composed of manganin strip material paired with either brass (for ratings below 10,000A) or copper (for 10,000A and higher ratings), featuring constant current distribution to shunt strips and standard accuracy of ±0.25% (with 0.1% accuracy available upon request).
The specification includes detailed dimensional tables for 20 different catalog number configurations across two output ranges. Key technical recommendations address mounting requirements, operational limits (shunts should run no more than two-thirds rated current under normal conditions), temperature constraints (manganin strip must not exceed 145°C), and installation guidance regarding lead length considerations, parallel connection capabilities, and proper vertical orientation for air convection. Terminal blocks are slotted to receive one-quarter inch bars, and dimensional tolerances are specified at ±0.015 inches for hole diameters and ±0.030 inches for other measurements. The document includes a technical drawing with component layout, dimensional diagrams, and a detailed illustration of the shunt assembly showing the stacked copper blade construction with terminal blocks.

DC AMMETER SHUNT
SERIES 205
RECOMMENDATIONS
- Shunts should be mounted on the grounded side of the circuit (or mounted on the grounded side of circuits above 750 volts for panel mounted shunts with insulated bases.)
- Shunts should run for no more than two-thirds (2 3⁄ ) the rated current under normal conditions as per AIEEE standards.
- The manganin shunt strip must not exceed 145°C, as this will cause permanent change in resistance.
- If longer lead lengths are necessary, the additional IR (millivolt) drop in the leads must be taken into consideration when ordering instruments.
- Shunts may be connected (without error) in parallel to measure heavy currents providing each shunt has a separate pair or millivolt leads connected to the instrument terminals.
- The resistance blades of the shunt should be mounted in a vertical position with the longitudinal axis of the shunt in a horizontal position in order to promote the free convectional flow of air.
