ITECH IT7800 High-Power Programmable AC/DC Power Supply

The ITECH IT7800 is a series of programmable AC/DC power supplies. In a 3U housing, they offer power up to 15 kVA, voltage ranges up to 350 V L-N and 500 V L-N. The output power can be increased up to 960k VA by configuring master-slave parallel. The devices have an intuitive LCD touch panel interface. The IT7800 series devices also have a built-in power meter and arbitrary waveform generator. The generator can simulate harmonics and other arbitrary waveform output. For models IT7806-350-90 and higher the users can choose single phase, three-phase, reverse phase, and multi-channel totally 4 output modes. With programmable outputs and complete measurements the ITECH IT7800 series is designed for new energy, power electronics, research institutes etc.

• Up to 15 kVA in 3U size; master-slave parallel with current sharing technology, up to 960 kVA - multiple units in parallel work as one.
• Voltage up to 350 V L-N, 500 V on request.
• Output frequency 16...2400 Hz, programmable slew rate setting for changing voltage and frequency.
