Switchmode Power Supplies from 2KVA..500KVA

Solid State SwitchMode Power Supplies

PCTI provides the highest current/power ratings of any high-frequency switchmode power supplies (SMPS) available globally. PCTI SMPS 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. PCTI SMPS are solid state IGBT based on DSP PWM (digital signal processor, pulse width modulated) technology.

For Your Application

PCTI's SMPS power ratings can range from 2KVA/KW to 500KVA/KW and include AC/AC, AC/DC, DC/DC and DC/AC designs. Options for our SMPS include any voltage input or output, EMI/RFI filtering, computer control via RS232, RS485, IEEE488/GPIB, or remote analog signals. Typical applications include communications, transportation, industrial processes and more.

Custom Products Designed for You

Our SMPS are built to customer order from a range of standard power and control modules, and offer high performance, high reliability and sophisticated control systems. A variety of computer interfaces are available to meet all of your power supply programming and control requirements. If you need help in specifying your SMPS, contact PCTI or request a quote.
