Power Inverters and Converters

From 1KVA to 500KVA

PCTI can provide the inverter you need for your specific application whether you need to change the service from AC or DC to another or change the frequency.   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, click here for an Inverter Application Data Sheet.

Frequency Converter, 480VAC, 60Hz/480VAC, 400Hz

 

Our power inverters are built to customer order based on our standard designs and offer high performance, high reliability and sophisticated control systems. A variety of computer interfaces are available to meet all of your inverter programming and control requirements.  Click here to view some representative  Inverter project profiles.

Inverter Specifications

 

PCTI inverter and converter capabilities can support any combination of AC or DC inputs and outputs falling within the general parameters indicated below.   DSP control and monitoring can also allow for universal AC inputs to accommodate a wide range of inputs spanning the variety of global distribution services.
