Lovato DMK20 - FLUSH-MOUNT LED MULTIMETER - NON EXPANDABLE - 47 ELECTRICAL PARAMETERS - BASIC VERSION - AUXILIARY SUPPLY 208-240VAC

General characteristics

DMK 2... digital multimeters are available with flush-mount housing, 96x96mm/3.78x3.78”. They monitor and view reliable readings of electrical parameters, even in the presence of critical operating conditions, such as voltages and currents with high harmonic content and variable frequency.
The total and partial hour counter provides an interesting feature for electric panels of emergency generating sets.
The diversified and accurate measurements give the multimeters valuable technical and cost effective advantages with respect to traditional analog instrumentation.

DMK2... digital multimeters view 47 electrical parameters:
– Voltage: phase, line and system values
– Current: phase values
– Power: active and reactive values, apparent phase.
– P.F.: power factor per phase
– Frequency (measured voltage frequency)
– HIGH/LOW: instantaneous minimum and maximum values of each phase voltage and current, total active power (W), total reactive power (var) and total apparent power (VA) values
– Total hours: non-volatile clearable log for DMK 20
– Partial hours: non-volatile configurable log for DMK 20
– Active and reactive energy meters for DMK21 and DMK22 only.
