The DMK 2 series can monitor and view readings of electrical parameters, even in presence of critical operating conditions, such as voltages and currents with high harmonic content and variable frequency.
The total and partial hour counter feature 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 respect to traditional analog instrumentation.
The Digital multimeters view 47 electrical parameters:
Voltage: phase, line and system values
Battery voltage: 9-32VDC for DMK 25 and DMK 26 only
Current: phase values
Power: apparent phase, active and reactive values
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 (YW), total reactive power (Yvar) and total apparent power (YVA) values
Total hours: non-volatile clearable log for DMK 20,DMK 25 and DMK 26 only
Partial hours: non-volatile configurable log for DMK 20,DMK 25 and DMK 26 only
Active and reactive energy meters for DMK21 and DMK22 only.
Auxiliary supply voltage range: U 154-288VAC for DMK 20 U 177-264VAC for DMK 21-DMK 22 U 9-32VDC for DMK 25-DMK 26
Voltage measurement range: 60-830VAC phase-phase 30-480VAC phase-neutral
Current measurement range: 0.05-6A
