DC/AC Power Inverters from 5KVA to 500KVA

For Your Application

PCTI can provide the DC/AC inverters you need for your specific application. PCTI inverters are digital signal processor (DSP) controlled based on IGBT PWM technology. This superior next-generation control allows us to provide a single control board solution for the inverter, thus increasing reliability by reducing control components. Whether you need a high quality AC waveform suitable for sensitive electronic equipment or some other purpose, contact PCTI about power inverters for more details. If you need help in specifying your inverter, contact PCTI or request a quote.

Custom Products Designed for You

Our power inverters are built to customer order based on our standard designs and offer high performance, high reliability and sophisticated control systems. Applications include remote power stations, grid tie in systems (including dc power supplies for grid tie systems), microgrids, renewables including wind, solar, fuel cells, transportation, backup power, overhead cranes, as well as many others. A variety of computer interfaces are available to meet all of your inverter programming and control requirements.

Following are our standard specifications.
