The PST26 , AC-DC converter in an eurocard format, incorporate input and output protec�ons and filtering, signalling features, required in most

of the severe environments for industrial applica�ons. The PSU provides significant advantages such as flexibility of output configura�on, high

reliability thanks to the integra�on of Vicor Corp. modules, high efficiency, low ripple and noise levels, input-to-output isola�on, so� start, over-

temperature protec�on, input over/undervoltage lockout. The input is protected against surges and transients and EMI filtered. The outputs are

coun�nuously short-circuit proof . LEDs in front panel indicates the status of the outputs.
