Product of Bender

The main advantages of PEM33x Power Analyzer are as described below:

  • Class 0.5S for energy
  • THD V and THD I measurement
  • Modbus-RTU communication option
PEM33x Power Analyzer, as well as measuring the general grid parameters like voltage, current frequency, power values etc.. It can also measure THD (Total Harmonic Distortion) too. PEM33x Power Analyzer makes energy measuring with Class 0.5 s according to IEC 62053-22 standard where voltage and current measurement sampled with a high precision as 0.2%. This precision is same with the industrial meters which are used for billing system. Measured data can be read from its LCD display easily. It is possible to remote reading and monitoring from our ActWin Smart software on PC over RS485 interface by Modbus-RTU protocol. Read data can be transferred to SCADA systems if required. There are 2 digital inputs and 2 digital outputs on PEM33x Power Analyzer. These outputs can be programmed relating to digital inputs or current, voltage, power measurement values. PEM33x Power Analyzer has a large ranges of transformer ratios as 1 … 2200 for voltage, transformer and 1 … 6000 for current transformer. Current and voltage terminals are closed by insulated terminal cover for isolation. Device measures active and reactive energy in two directions of energy regarding the connection point, and records the measurement value. PEM33x Power Analyzer can calculate as well the neutral current by using current unbalance. On board with 96x96 mm size makes it easy for general use. With 1.6 kHz sampling rate, power quality monitoring is accurately done and stored.
