Lovato DMG110 - MODULAR LCD MULTIMETER - NON EXPANDABLE - BACKLIGHT LCD ICON DISPLAY - RS485 PORT - AUXILIARY SUPPLY 100-240VAC/115-250VDC - MULTILANGUAGE - ITALIAN - ENGLISH - FRENCH - GERMAN - SPANISH AND PORTUGUESE

General characteristics

DMG... digital multimeters are available with a modular housing, 4 module size, and are equipped with a graphic backlight LCD (except DMG 100/101/110 with icon display) capable of providing extremely clear, intuitive and flexible viewing of all electrical parameters of an installation.
For DMG 110 and DMG 210 versions, there is a built-in isolated RS485 interface, while DMG 101 features 2 programmable digital inputs and 2 outputs.

Main measurements:
– Voltage: phase, line and system values
– Current: phase values (neutral current calculated)
– Power: apparent, active and reactive phase and total values
– P.F.: Power Factor per phase and total
– Frequency of measured voltage value
– HIGH-LOW-AVERAGE value functions of all measurements
– Maximum demand of power and current values
– Asymmetric voltage and current
– Total harmonic distortion (THD) of voltage and current values
– Energy meters for active, reactive and apparent values
– Hour counter (total and partial, 1 on DMG 200/210, 4 programmable on DMG 100/101/110)
– Phase energy (DMG 100/110)
– Harmonic analysis up to the 15th order (DMG 100/110).
