SINGLE-PHASE METERING INSTRUMENTS 96x48mm FLUSH-MOUNT VERSION

LOVATO Electric continues to expand the range of digital metering instruments with the new DMK0 and DMK0…R1 models.
These new models, in a 96x48mm flush-mount housing, can be used in all those applications where there is a need to read and monitor diverse electrical parameters.
They are available in five different models:
- Voltmeter
- Ammeter
- Voltmeter or Ammeter – User has to choose between one or the other measurement
   by simply connecting it in the appropriate way and applying the correct front plate,
   standard supplied in the package
- Frequency meter
- Cosphi meter.
There are two versions put at the customers’ disposal:
- DMK0… basic metering instrument for selected electrical measurements
- DMK0…R1 besides metering, it also has one programmable relay output with one
   changeover contact to signal or activate preset protections in case of alarm
   conditions, e.g. disable a system in overvoltage out-of-limits conditions.

Specific features of the DMK0...R1 models only

  • Programmable relay output

  • LED indication for protection tripping

  • Programmable tripping thresholds 

  • Programmable tripping delay time available for each threshold

  • Programmable function consenting to have faster tripping time proportionally to measure shifting respect with the programmed limit

  • Trip resetting, selectable manual or automatic

  • Automatic resetting with programmable delay

  • Memory function with option to storing the relay state at power loss and then reset it at power return

  • Option to select relay state during regular operation, positive fail-safe operation.
