PAC3220 power monitoring device for electrical variables, Modbus TCP, DC extra-low voltage supply
Brief summary:
Power monitoring device for front-panel mounting for the acquisition of basic electrical variables, such as voltage, current, power, etc. and power quality (THD). PMD-III according to IEC 61557-12. Multifunctional inputs and outputs for expanded function scope and standard Modbus TCP 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.

- 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; active, reactive and apparent energy, per phase and total
- Import and export
- THD for voltage (UL-L/UL-N) and current (IL)
- 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
- Active energy history per day and tariff over the last 2 months for import and export
