PAC4220 Power monitoring device for electrical variables, power quality and storage AC/DC wide-voltage supply

Brief summary

Power monitoring device for front-panel mounting with high measuring accuracy, for the acquisition of basic electrical variables, such as voltage, current, power, etc. and specific variables relating to power quality (THD and individual harmonics per phase for voltage and current). PMD-III according to IEC 61557-12. Multifunctional inputs and outputs for expanded function scope, storage and standard Ethernet interface for easy integration into higher-level software systems.

The product forms the basis for efficient and sustainable operation over the entire lifecycle of the plant by determining and transmitting measured and status data.

Description of the measurement function:

• Automatic line frequency detection
• 4-quadrant measurement (import and export)
• Can be used in 2, 3 and 4-wire systems
• Suitable for TN, TT and IT systems

Measured values:

• Voltage (UL-L/UL-N), phase currents (IL), neutral current (IN)
• Frequency, power factor, cos phi
• Active, reactive and apparent power per phase and total
• U/I phase diagram in graphical and table form, as well as asymmetry for voltage and current

• THD for voltage (UL-L/UL-N) and current (IL)

• 2nd to 63th harmonic components (even and odd) per phase for voltage
• 2nd to 63th harmonic components (even and odd) per phase for current

• Instantaneous, minimum, maximum and average values
• Averaging of all measured values directly on the device in two aggregation stages, which are independent of each other and freely configurable
• Energy consumption for active, reactive and apparent energy for import and export

• Number of energy tariffs: 2
• Phasor plot
• Operating hours counter

Functions:

• Display of over 200 measured values, including values for active, reactive and apparent energy

• Recording of load profile for apparent, active and reactive power average values with minimum/maximum rms values
  • Definable period length  
  • Load profile data with time stamp and tariff information ( on-peak and off-peak tariff)
  • Additional information, e.g. time synchronism, supply voltage failure and data validity

• 2 optional slots for subsequent function expansion by means of plug-in modules
