Product Introduction

SPM20-D is specially design for telecommunication base station application to calculating power consumption, measuring DC device electricity. It is the smallest DC multi-channel Energy Meter with compact design, consists of main module and measure module. Very user-friendly installation to simplify the installation process in a compact size.

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-D DC multi-channel monitoring unit is designed for DC power distribution system terminal, which is a set of monitoring programs. It consists of measuring unit and measuring module, the connection between them is the PLbus that developed by Pilot. PLbus uses daisy-chain bus topology, the connector uses the RJ12 plug, it greatly simplifies the wiring on site.

SPM20-D is mainly applied to base station communication power system, it can support up to 12 measurement modules. With current, voltage, power and other parameters of the measurement and energy metering function, maximum support 63A current measurement, can meet the needs of different on-site applications. The measuring unit supports DIN35 rail mounting and backplane screw mounting, the measurement module is a direct access installation. Standard RJ12 connection make the wiring easily to customer.

SPM20 provides the main function as below:

1.Real-time measuring data :Voltage, Current ,Power
2.Metering function :Input power, Output power, Total energy
3.Alarm function :Over current,Under voltage, Over voltage , Module fault alarm 4.Communication function :1 channel 485 communication, Modbus-RTU
