The TTi HA1600A is a self-contained single-phase harmonics and flicker analyser with a built-in high-resolution LCD display for real-time compliance testing. It functions as both a harmonics and flicker analyser and a full power meter, measuring voltage, current, power, power factor, THD, crest factor, phase angle, frequency and inrush current simultaneously. Compliant with EN 61000-3-2 and EN 61000-3-3, it supports both 115V and 230V operation and includes PC software (HA-PC Link Plus) with RS-232 and USB interfaces for data archiving and reporting. For full compliance testing, the optional AC1000A clean power source is recommended.
