Switched Mode Power Supply Specifications

PCTI switching power supplies 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 switched mode power supplies (SMPS) are solid state IGBT based on DSP PWM (digital signal processor, pulse width modulated) technology.
