The A200-HAS is an economical and precise solution for DC current measurement in electrical systems up to +/- 100A in capacity. The output of the device has a positive slope (Vcc / 2) when an increasing current flows through the primary copper conduction path. The internal resistance of this conductive path is 130 µΩ typical, providing low power loss. The thickness of the copper conductor allows survival of the device at up to 5× overcurrent conditions. The terminals of the conductive path are electrically isolated from the sensor leads and provide a minimum isolation of 3,000V. Current sense response time is 3uS. Power requirements are 3V @ 10mA. Signal output is linear and varies from 0.0V (-100A) to 3.0V (+100). Zero current is represented by 1.5V. The sensor has two 1/4" terminal posts for connection to the power bus. Supplied with a 48" color coded cable. When installed in accordance with the approved instructions and as part of a qualified instrument system, this current sense shunt is STC'd as a primary replacement.
