Electronic Systems! Universal Meter for Motors, Power Electronics /Electronic Systems'— Mu11i-Channel Precision Power Meter

meter is another advanced product from ZES ZIMMER LMG series of precision power meters, tried and tested and with great acceptance in the versal meter for the entire field work analysis. It can be used in practically all power electronics and test systems, in quality as- It is fully frequency inverter Of course, it can also be used switched power supply units. It is also suitable for mains analysis measurements. Easy operation thanks to colour graphics display and measured values Various value tables can be called on the colour graphics either with six values in large letters, which can...

Compensated current clamp Part No. L45-Z06 A special current measuring device is the compensated current clamp by ZES ZIMMER. It features electronic compensation of amplitude and delay errors. Even at low current levels of 1A to 40A, measurement is exact in the frequency range from 5Hz to 20kHz. Due to its high dynamic common-mode rejection, this current clamp is also very suitable for carrying out measurements at the frequency inverter output. Compensated current clamp L45-Z06 Various methods of applying current to be measured 4mm safety sockets 600V CAT III Direct measurement...

Measurement on two systems In wiring A:l+2 B:3+4, the only one LMG450 is needed for for speed variable drives or with different frequencies ARON circuit is two times used, complete measurement. frequency conversion have no The block diagram shows that Generally frequency converters neutral on input or output. The following block diagram variable drive. This example is The screenshots were made with applies wiring A:l+2+3 B:4 and used to explain the settings the free software BMP2PC from is typical for a low power speed and displays of the LMG450.

Dimensioning of insulation for all standard low voltages The measurement inputs are dimensioned for ­ 00V/CAT III, 6 with option L45-O15 up to 1000V. This makes it possible to measure in all standard 3-phase low voltage networks. The adjacent table shows that the voltage “Line to Neutral/ Earth” is always less than 600V. Line to Line Voltage Technical Data Voltage measuring ranges Nominal value /V Maximum trms value /V Maximum peak value for full scale /V Overload capability Input impedance Current measuring ranges Nominal value /A Maximum trms value /A Maximum peak value for full scale /A...
