MULTIMETERS TYPES DMK 21, DMK 22, DMK 51 AND DMK 52 WITH ENERGY
METERS
DMK
21, DMK 22, DMK 51 and DMK 52 multimeters monitor and view reliable
readings of electric parameters, even in presence of critical
operating conditions, such as:voltages
and currents with high harmonic content and variable frequency.
They view 47 electric parameters:
- Voltage; phase to phase and system values
- Current; phase values
-Power; active, reactive,
phase apparent values
- Power factor per phase
-Frequency; values of measured
voltage
- Active and reactive energy meters
- HIGH/LOW; instantaneous maximum and minimum values per phase of
voltage and current measures, total active power (ΣW), total
reactive power (Σvar) and total apparent power (ΣVA).
The DMK 22 and DMK 52 types also come equipped with an RS485 serial
interface providing for remote supervision of the electric
parameters via personal computer.
The DMK 22 and DMK 52 additionally can view seven other parameters,
using the Modbus®
protocol, such as:
-Maximum value of total active power
-Maximum value of current, 3 measures
-Maximum asymmetry of phase to phase voltages
-Percentage of current imbalance
-Average current value.
