DESCRIPTION

Digital individual ground alarm SZITS-D is of use as electric main critical insulation resistance control which is powered by a single electric power supply.

Designated area: functioning and going up automatic – and communication installations.

Similar equipment: SZI1, SZI2, SZIU, SZITS.

Equipment details:

  • additory voltage range (280 +40 V)

  • dielectric resistance status data transfer possibility to the dispatch control system

  • all types of electric power supply have equal manufacturing

  • built-in microprocessor

  • high fire safety of the device (due to current protection- and thermal shutdown add-in components)

  • leakage value in field qualitative assessment without the use of an additory milliamperemeter

  • slow response by voltage pattern excursion

  • application possibility of changing in direction of movements in diagrams

  • may be used for cable circuits – and signaling, centralization and blocking equipment dielectric resistance control

Component parts:

  • SZITS (according to order number)

  • engineering instruction (1 pcs per 6 devices)

  • label (1 pcs per a device)

  • PP-SZITS checkout console (optionally)

We deliver the equipment around the Country and to the CIS region!
