Informace o výrobku "PM-3033 Modbus RTU 3-Phase Power Meter, 1A/5A CT Input"
PM-3033 CR is a three-phase power meter with an RS-485 port running Modbus RTU. It reports true RMS voltage and current, active, reactive and apparent power and energy, power factor and frequency, with data refreshed once per second, so engineers can track consumption on running equipment.
Current inputs accept 1A or 5A secondary-side CTs directly, so dedicated metering CTs are not needed, which keeps installation costs down. The meter supports 3P4W, 3P3W, 1P3W and 1P2W arrangements, accepts voltage inputs from 10 to 500 V, and can be used on both low-voltage primary-side and secondary-side circuits.
The baud rate is selectable by DIP switch (9600, 19200 default, 38400 or 115200), and data formats run from N,8,1 (default) to O,8,2. The plastic DIN-rail housing provides 3000 VDC isolation on the serial port and operates from -20 to +70 °C.
Applications
- Generator monitoring
- Switchgear distribution systems
- Energy management
