Product Introduction

SPM20 is CE certificated for sub-metering, it suitable to Power distribution cabinet and switch cabinet of the Low-voltage distribution system less than AC 220V, and support to single phase two wires and three-phase four-wires system.

Fully comply the following EMC Standard:
IEC61000-4-2,IEC61000-4-3,IEC61000-4-4,IEC61000-4-5,IEC61000-4-6,IEC61000-4-11,IEC62052-11 2003, and CISPR22:2006.

Any metering combinations of: Single-Phase and Three-Phase are possible allowing users to provide flexibility with installations of electrical metering systems.Installation is achieved using Current Transformers (CT).

SPM20 CMS is a monitoring system especially to the power terminal by its micro distributed multi-circuit monitoring unit. It consists the measurement module and control module, and these two modules is connected by the PLbus general line which is also researched by Pilot, and the connector plug is by the standard RJ12 which can simplify the installation on site.

SPM20 widely be used in Hotel,Healthcare, Dormitory, Commercial Building, Office, Residential Building, and Reconstruction Project. One monitoring unit can support 30pcs measurement modules at most, and can monitor 10 three-phase circuits or 30 single phase circuits, and have the measurement and metering function to the general data of the three-phase branch (general power, total electric-energy). Its current measurement is in maximum 63A, can satisfy the different application on site.

The micro distribution multi-circuit measurement unit can be for multiple installation, and the controller conforms to DIN35 rail install, and backboard screw fixation install; There are the closed in line installation and opening buckle mounting for the option as required. The connection between the measurement unit and controller is by the standard RJ12 port, can make the wiring arrangement easy on site.

SPM20 provides the main function as below

1.Realtime Measurement Voltage, Current, Active power , Reactive power, Apparent Power, Power Factor, Frequency
2.Energy Consumption Active energy，Reactive energy
3.Alarm Function Overload, Under load, Over current, Sensor fault
4.Communication 1 RS485 port, MODBUS-RTU protocol
