Measurement Speed: Approximately 2 times per second.
Dimensions: 54mm x 80mm x 64mm (standard 3P DIN rail width). Wiring & Installation Instructions
Before starting, ensure the power is completely off to prevent electric shock. The D52-2066 Manual PDF outlines two primary wiring methods depending on the Current Transformer (CT) type: ---- D52-2066 Manual Pdf
Measuring Voltage: Connect the incoming AC lines to terminals 1 and 2.
Current Measurement (Internal CT): Thread the load wire (either live or neutral) through the round hole in the center of the meter. The direction of the wire does not affect the reading.
Current Measurement (External CT): If using an external transformer, thread the load wire through the external CT's hole, then connect the two secondary wires from the CT to terminals 3 and 4 on the meter. Operating Features
Energy Reset (Clear kWh): To reset the accumulated electric energy to zero, press and hold the SAM CK button (located on the front panel) for 5 seconds while the device is powered on.
Memory Function: The meter automatically saves energy data during power outages. When power is restored, it will continue accumulating from the last saved value.
Backlit LCD: The device features a full-view colorful display, ensuring visibility in low-light electrical cabinets. Safety & Usage Warnings
Grid Type: This meter is strictly for Pure AC 45-65Hz city power. It may be damaged if used with square wave outputs from certain low-cost inverters or non-standard regulators.
Voltage Range Selection: Ensure you have the correct model for your system. The 40–300V model is standard for 110V/220V systems, while the 200–450V model is intended for 380V industrial power. Use of the 450V model on a 220V system may result in inaccurate readings.
