A comprehensive range of high accuracy multi function digital metering systems, specifically designed to provide switchboard builders with the exact level of functionality required for individual power monitoring applications. For example, the 0340 model provides basic measuring and monitoring capabilities, rising up to the 1540 which offers detailed parameter status information, inclusive of harmonic distortion. All products offer programmable potential and current transformer ratios, and power measurement parameters via a simple menu driven user interface. The status of all parameters can be viewed by scrolling through a number of screens featuring a high quality LED display. Integra digital metering systems are ideal for new projects, and can provide a technological facelift with reduced space and wiring benefits to retrofit projects.
