Port Definition
- Input voltage: When the line voltage is less than or equal to 500 V, connect the meter directly. When the line voltage is greater than 500 V, connect the meter through potential transformers.
- Input current: When the input current is 0 A to 80 A, connect the meter directly (channel 1). When the input current is greater than or equal to 80 A, connect the meter through current transformers (channel 2).
Installing the YDS60-80
- Install the Smart Power Sensor on the standard guide rail of DIN35mm.
- Press the Smart Power Sensor downwards onto the guide rail, and then push it in place along the guide rail.

- You need to set parameters after cable connections are complete. For details, see section 4 “Display and Parameter Settings”.
- This meter is generally used in commercial and industrial high-current scenarios. In external CT scenarios, the precision of the secondary-side current is ±5 mA. For example, if a CT with a transformer ratio of 400/1 is selected, the error is ±2 A. This meter is not recommended in scenarios where the plant power is low or the control precision of the grid-connection point is high. Instead, use a meter with higher precision.
