The SATEC PM135 is a compact range of multifunction three-phase power meters designed for reliable electrical measurement and straightforward integration into industrial and utility control and monitoring systems. The range measures voltage, current, active, reactive and apparent power, power factor and frequency, with RS-485 (EIA-485) as standard and optional communication interfaces for integration with PLC and SCADA systems.
The PM135 is commonly specified for plant switchboards, MCCs and utility metering panels. Energy and TOU metering, power demand and data recording are provided by the PM135E and PM135EH.
The range covers straightforward three-phase power and energy metering, with harmonic analysis available in the PM135EH, for applications where the functions of a full power quality analyser are not required.The SATEC PM135 range is designed for three-phase measurement in LV and MV panels. It supports direct voltage measurement up to 690 V AC line-to-line or measurement through external voltage transformers for MV applications, together with 1 A or 5 A CT secondary inputs and optional SATEC HACS current sensors.
Depending on the wiring configuration, the range measures line-to-line and, where applicable, line-to-neutral voltages, line currents, active, reactive and apparent power, power factor, frequency, neutral current and voltage and current unbalance. Energy measurements are available in the PM135E and PM135EH.
One optional plug-in expansion module can be fitted to each meter. Depending on the selected configuration, this may provide digital inputs, relay outputs, analogue outputs or an additional communication interface for status monitoring, alarms and control within industrial systems.The PM135E and PM135EH provide non-volatile event and data recording. The event recorder stores time-stamped configuration changes, resets and internal diagnostic events. Two data recorders can log selected measurements at configurable intervals and support automatic daily energy and maximum-demand profile logging.
Waveform functionality is separate from the event and data logs. Real-time scope-mode monitoring through PAS software provides a live view of voltage and current waveforms for commissioning and diagnostic work.
Together, the stored records and live waveform view support commissioning and diagnostics. They do not replace a dedicated power quality analyser or protection device.The PM135 range integrates with PLC and SCADA systems through a standard optically isolated RS-485 port and optional communication interfaces. Depending on the communication option ordered, supported protocols can include Modbus RTU, DNP3, SATEC ASCII and IEC 60870-5-101 on serial interfaces, and Modbus TCP, DNP3/TCP and IEC 60870-5-104 over optional Ethernet. PROFIBUS DP and an additional RS-232/RS-422/RS-485 interface are also available as plug-in options.
A single plug-in expansion module can be fitted to each meter. The functions available depend on the selected module and may include digital inputs, relay outputs, analogue outputs or an additional communication interface.The PM135 range is used where dependable three-phase electrical measurement and communications are required. Typical applications include industrial monitoring and sub-metering in manufacturing plants, process facilities and commercial buildings, as well as metering in MCCs, switchboards and distribution panels.
In utility and infrastructure projects, PM135 meters can be integrated into LV and MV monitoring schemes using protocols including Modbus RTU, IEC 60870-5-101/104, DNP3 and PROFIBUS DP. Applications also include energy monitoring and cost allocation in data centres, hospitals and multi-tenant facilities.The SATEC PM135 is a compact range of multifunction three-phase power meters designed for reliable electrical measurement and straightforward integration into industrial and utility control and monitoring systems.
