1. Introduction
This document provides operating, maintenance and installation instructions
of A-45 series. The unit measures and displays the characteristics of single
phase two wires application. It provides voltage, current, power, frequency,
power factor and energy information. A-45 series has both direct connect types
and 5A CT operated types. The direct connect type can work with direct load
45A. Two Pulse outputs and 1 remote communication port is provided.
This series covers 3 models:
