AC Isolation Amplifier
AD-SWK 3


back to products

  Description

With the current converter AD-SWK 3 up to three independent alternating current magnitudes can be converted to three alternating voltage of 0-10 V. The frequency-response curve at the output is equivalent to input. Inputs, outputs and supply voltage are galvanically separated from each other with high insulation. The outputs refer to a common mass. An integral electronic wide range power pack with high efficiency prevents strong increase in heat.

  Application

For conversion of up to three alternating currents to three alternating voltage
