Product Features

Product Overview:

The AHLC-LTA series DC leakage current sensors are developed using magnetic modulation and zero flux principles, providing electrical isolation and piercing measurement for weak DC mA-level micro currents, featuring excellent accuracy, linearity, and stability. They are widely used in various industries such as DC power transmission, DC switchboards, battery detection, power supplies, photovoltaic, wind energy generation, medical equipment, and communication base stations.

Cautionary Notes

1. When using a DC leakage current sensor, to achieve good dynamic characteristics and sensitivity, it is essential to pay attention to the primary coil.

The coupling between the auxiliary winding and the main winding is recommended to be achieved using a single wire, ensuring that the wire completely fills the through-hole in the Hall sensor module.

2. The DC leakage current sensor can only achieve the specified measurement accuracy under the rated input current value; when the measured

When the current is significantly below the rated value, to achieve accuracy, the primary side can use multiple turns, i.e., IpNp = rated ampere-turns. Alternatively,

The temperature of the original edge feed line should not exceed 80℃.

3. The auxiliary power supply for the DC leakage current sensor during normal operation should not exceed ±20% of the calibration value, and the ripple should not exceed ±1%.

4. Do not drop the DC leakage current sensor from a height of ≥1m during installation and use.

5. No adjustment for zero point or full-scale potentiometer.

6. The auxiliary power supply needs to be configured independently; the positive and negative poles of the power supply must not be reversed.

7. It is recommended to use shielded cables for output signal lines.
