NEF30-MC digital meters constitute a development of the NEF30 series that has so far included control buttons, lamps and signal indicators. All NEF30-MC indicators feature the same characteristics:
the possibility of installing in a standardised Ø 30.5mm hole, and a wide range of supply voltage – 24÷230V AC/DC.
Their design has been coordinated with other devices of the NEF30 series. They have been adapted to be used together with NEF30 devices, as panel-mounted meters for industrial applications. The meter has two programming buttons (their functions depend on the meter’s version), which are accessible, after removing the front cover.
Types of meters
The NEF30-MC-VAC meter is a voltmeter, intended primarily to monitor voltage in a 230V AC power network.
The NEF30-MC-AAC ammeter is used to measure alternating current, within the range of 1A, either directly or from a measuring transformer.
The NEF30-MC-A 5A AC ammeter is used to measure alternating current, within the range of 5A, either directly or from a measuring transformer.
