Produktinformation "PM-2133DP 3-Phase Power Meter, Modbus RTU, LED Display"
The PM-2133DP CR is a 3-phase power meter with an RS-485 Modbus RTU interface, suited to energy management and power monitoring on low-voltage primary-side and medium/high-voltage secondary-side circuits. It accepts an input voltage range of 10 to 500 VAC and provides true RMS readings of voltage, current, active, reactive and apparent power, energy, power factor and frequency.
An 8-digit LED display allows key parameters to be read locally at the panel, which is useful for engineers commissioning or checking a distribution board without a supervisory system. The meter is designed for panel mounting and supports several wiring arrangements, including 3P4W, 3P3W, 1P3W and 1P2W.
Current transformers are not included by default. Select CTs with a 333 mV voltage output to match the application; the CT ratio must be set correctly for accurate readings. Rogowski coils are not supported.

- Generator monitoring
- Switchgear distribution systems
