Multifunctional Electric Power Parameter Meter
The PM126 series color graphic multifunctional power parameter meter is powerful. In addition to full electrical parameter monitoring functions, it also features asymmetrical components, unbalance degree, harmonic analysis, timestamped extreme value recording, demand/maximum demand, limit alarms, SOE event recording, and other powerful functions. It comes standard with an RS485 communication interface and can be optionally equipped with a second RS485 interface or a wireless 485 interface. It has various expansion modules (up to 8DI/6DO/2AO/2PO...), which can be flexibly selected as needed. It has been widely used in distribution cabinets, SCADA systems and energy management systems, substation automation, distribution network automation, community power monitoring, industrial automation, and intelligent buildings.
The PM126 features 0.5s level accuracy and supports multi-rate functions with multiple time zones/time periods/rates, meeting the needs of high-precision monitoring, internal sub-metering, and energy management applications. It is easy to install, simple to wire, requires minimal engineering effort, can be programmed on-site, and supports networking with different PLCs and industrial control computer communication software.
The PM126 series uniquely features a large-screen color graphic LCD display with multiple languages (including Chinese). In addition to numerical values, it can also display harmonic spectrum graphs/waveform graphs, etc.

Function Overview
■ Real-time measurement: current, voltage, active/reactive/apparent/phase power, power factor, frequency, load nature, load rate, four-quadrant power display, and other information
■ Electric energy and complex tariff time-of-use energy: 0.5s level bidirectional metering, forward/reverse/absolute/net active/reactive energy; complex tariff time-of-use energy: 6 time zones, each with 12 periods, 4 tariff types
■ Demand and maximum demand: real-time current/power demand, maximum demand;
■ Maximum/minimum value recording: real-time statistics of maximum and minimum values of each phase/line voltage, each phase current, active power, reactive power, apparent power, power factor, frequency, imbalance, THD, etc., with timestamps; maximum/minimum values can be cleared on the screen;
■ Limit alarm: corresponding parameters can be set for monitoring, with high/low threshold and delay settings. Alarm triggers after exceeding threshold, can activate DO action, and records alarm events.
■ Asymmetric components: positive sequence/negative sequence/zero sequence components; voltage/current imbalance; phase angle calculation; can be displayed graphically and textually on the color screen;
■ Harmonics: THD, 2nd-63rd order harmonic analysis, telephone interference factor, current K factor, crest factor, etc.; screen can display harmonic analysis values and frequency spectrum bar chart;
■ Wave recording and waveform display: can display current and voltage waveforms in real time, store up to 10 waveforms based on set conditions.Product Selection
