72x72 mm panel digital multimeter - TENSE (DAV-72D)

Product description:
The DAV-72D is a combined single-phase digital voltmeter-ammeter designed for continuous monitoring of AC voltage between phase and neutral conductor and load current consumed, measured by an external current transformer (CT-120, included). The instrument is suitable for electrical panels, production installations, and energy distribution or monitoring systems.

Operating principle and use:

• Connection to the phase and neutral conductor to be measured through the voltage measurement terminals.

• Current measured through an external CT-120 current transformer, whose secondary conductors connect to terminals K and L on the back of the instrument.

• When power is applied, the following is displayed:

  • Current phase voltage (V)

  • Load current (A)

Installation and configuration:

• Front panel mounting (cutout 68 × 68 mm)

• Wiring of the CT-120 as indicated in the diagram, load wire routed through the transformer

• Do not use other current transformers - the instrument is specifically calibrated for the CT-120
