High-Performance Programmable AC Power Supply
AC, DC, and AC+DC Output
The ITECH IT-M7700 Series is a programmable AC power supply for development, production, and ATE systems.
In addition to AC and DC output, it generates AC+DC signals with an adjustable DC component. Depending on the model, up to 1,500 VA, 600 V, and 1,000 Hz are available.
Reproduce Mains Disturbances Under Defined Conditions
The IT-M7700 Series generates user-defined and distorted voltage waveforms for reproducible testing of mains disturbances. In List Mode, voltage, frequency, and interruption profiles can be output automatically in a defined sequence.
Measurements and Harmonic Analysis
The integrated AC power meter measures RMS voltage, RMS current, frequency, active power, and power factor. Within the 45 Hz to 50 Hz frequency range, the series analyzes voltage and current harmonics up to the 50th order.
Test System Integration
USB and LAN support remote control; GPIB, RS-232/CAN, and analog/RS-485 are optional. Supported models can be connected in series in pairs.
A three-phase output requires three identical units: each unit generates one phase, the system bus synchronizes the units, and the outputs are connected externally in a star configuration.
Functional Scope and Product Positioning
The series is designed for programmable AC, DC, and AC+DC power-input testing. Hipot and electrical safety testing, as well as standalone mains and power analysis, require specialized test and measurement equipment.
Alternative Products
For comparable AC, DC, and AC+DC test applications at 500 VA or 1,000 VA, consider the GW Instek ASR-2000 Series.
For higher power requirements, the GW Instek ASR-3000 Series provides programmable AC, DC, and AC+DC outputs for power-input and mains-disturbance testing.
