The ITECH IT7321 is a single-phase programmable AC power supply offering up to 300 VA power, configurable for 150 V at 3 A or 300 V at 1.5 A. Featuring high-precision linear amplification, it supports frequency and phase angle adjustments and includes comprehensive measurement and disturbance simulation functions. It’s ideal for power electronics testing, compliance checks, and lab environments..
The IT7321 belongs to ITECH's high-precision IT7300 series, designed for accurate and dynamic AC power simulation. Using a linear amplifier architecture, the unit provides extremely clean AC output, making it suitable for EMC testing, appliance verification, and grid simulation. Engineers can simulate power grid abnormalities and evaluate performance under transient or unstable power environments using built-in surge, dip, and waveform distortion modes.
The IT7321 supports a rich set of programmable features via list sequencing, pulse, and step modes. Each sequence can contain up to 100 programmable steps. It also integrates accurate true RMS metering, reducing the need for external equipment. With LAN, USB, and RS‑232 ports, the IT7321 easily connects to automated test environments. Its compact ½ 2U design and smart fan cooling make it easy to use in bench or rack systems.
