AD-SV 1224 GL

back to products


The power converter AD-SV 1224 GL is for increasing an available low supply voltage to a substantially higher value. An upward regulation switching with a high degree of sufficiency enables the operation of electric measuring converters, which demand a supply voltage of at least 20 V DC. An electric over current protection switches the device securely off during a short circuit at the output. To reset this fuse, a brief voltage separation at the input is necessary.


A mains supply is not always available at all installation sites. In such cases, one resorts to battery voltages with 12V DC, which are also possibly charged by solar energy. Almost all devices of the AD-device family work from a supply voltage of 20 V DC upwards and therefore can also be operated in remote areas. This also enables operation in vehicles with 12V board voltage.


  Specific characteristics

  • Increasing a voltage supply to a level required for operating a device.
  • It is not essential that the earth lead for the load is acquired from the AD-SV 1224 GL. The earth connection can also be carried out directly at the feeding voltage source.
  • Electronic overload protection with reverting characteristic and manual hold.
  •   Business data
