  Description

With the power supplies AD-SV 20 GS (1-channel) and AD-SV 40 GS (2-channel), external sensors and devices with a filtered DC voltage of about 24 V DC with max. 50 mA can be supplied.The output voltage is electrically isolated from the supply voltage and the second channel. For each channel, two different electronic current limiters are available, which can be alternatively selected via terminals. Due to the highly efficient integrated electronic wide range power supply high output loads are achieved with low power consumption and heating.

  Application

For an isolated power supply of external sensors etc. Devices with a DC separation, eg. 2 - or 3-wire transmitter
