DESCRIPTION

SZI is of use as electric main critical insulation resistance control as well as resistance level evaluation with the use of fixed all-digital display; electric main is powered by a single electric power supply.

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

Similar equipment: SZI1, SZI2, SZIU.

Equipment details:

  • all types of electric power supply have equal manufacturing

  • leakoff digital measurements

  • high fire safety of the device

  • DC power supply sides insensitivity low effect (force)

  • low insensitivity dancing by connection voltage – and tasting voltage excursion

  • there exists the possibility of an in field testing the attention device sensitivity

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

  • 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:

  • SZI (according to order number)

  • engineering instruction (1 pcs per 6 devices)

  • label (1 pcs per a device)

  • PP-SZI checkout console (optionally)

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