THREE-PHASE METERING INSTRUMENTS 96x48MM FLUSH-MOUNT VERSION
   
LOVATO Electric continues to expand the range of digital metering instruments with the new DMK1..., DMK1…R1 and DMK16.
Our modular digital metering instruments, in a  96x48mm flush-mount version, are used in three-power distribution boards, both in industrial and services fields, where voltage, current and active power need to be monitored.
They are available in four different models:
- Voltmeter
- Ammeter
- Frequency meter
- Cosphi meter.
There are two versions put at the customers’ disposal:
- DMK1… basic metering instrument for selected electrical measurements
- DMK1…R1 - DMK16 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 DMK1...R1 and DMK16 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.
