Product information
The PM135 is a powerful multi-functional power parameter measuring instrument. It provides high-precision power parameter measurement as well as power quality and harmonic analysis. It has Chinese display on LCD and can powerfully display waveform diagrams, harmonic spectrum diagrams and vector diagrams. Basic functions:
Multifunctional three-phase power parameter measurement:
■ Voltage, current (including neutral current), power, electrical energy (E and EH types), power factor, frequency, unbalanced voltage/current, maximum/minimum value, demand...
■ Current range up to 200%.
■ Supports frequencies: 25, 50, 60 and 400Hz.
■ Direct connection to 690V L-L (1.15 MV through PT).
■ 20ms data refresh.
■ Automatic recording of load curves.
■ Supports DC measurement by using Hall effect sensors.
Basic power quality (E or EH type):
■ Harmonics of individual voltages and currents (up to 40 times) (EH type).
■ THD, TDD and k-factor of voltage and current (EH type).
■ Maximum/minimum values with timestamps.
■ Waveform capture with 128 samples/cycle sampling rate.
■ Chinese menu, waveform display, harmonic spectrum display, vector diagram display.
■ Intuitive load rate bar indication/warning independent of the screen.
Metering meter (E and EH types):
■ Accuracy exceeds Class 0.5s, and the high-precision EH type can reach Class 0.2s accuracy.
■ 8-rate time-of-use tariff (TOU).
■ Calibration certificates with ISO17025 and ILAC accreditation can be provided. Event/data recording (E and EH models):
■ System event and data recording.
■ Real-time timestamp.
Communication protocol:
■ Standard RS485, optional second communication port (Ethernet, RS232/422/485, Profibus, CAN, GPRS, radio frequency).
■ Protocols optional: Modbus RTU, ASCII, DNP 3.0, Modbus/TCP, DNP3/TCP, Profibus DP, IEC 60870-5-101, IEC 60870-5-104.
■ Baud rates optional: up to 115.2kbps (MODBUS).
Alarm and control functions:
■ 16 programmable set points.
■ 4 counters.
Real-time clock:
■ Built-in real-time clock and calendar function.
■ Backup battery for RTC real-time clock.
Power supply:
■ Standard AC/DC power supply (85 - 265V AC, 88 - 290V DC).
■ Special power supplies optional (12, 24 & 48V DC).
Installation and dimensions:
■ Panel mounting: 92mm×92mm square opening or 4〞 circular opening.
■ Weight: 0.7kg / 1.5lbs.
■ Height×Width×Thickness: 114x114x109mm / 4.5x4.5x4.3〞.
■ One expansion module can be installed.
