2. Product Features:
YTLQ10-XX series current sensors are based on the principle of low-power coils. Compared with traditional transformers, they have the following advantages:
1. Integrates 3 phase current and 1 zero-sequence current sensors, small in size, light in weight, easy to install and use
2,. The secondary output is a safe low-voltage signal, without the risk of secondary open-circuit high voltage, increasing safety
3. The power consumption is greatly reduced and the heat generation is small
4. Standardized products, simplified selection and ordering process, and fast delivery
3. Implementation and Reference Standards
