LEM Current Transformer (CT) LF1005-S/SP36 & LF505-S/SP27
The LEM Current Transformers (CT) models are LF1005-S/SP36, and LF505-S/SP27 are specially devices used for measuring alternating current (AC) in VFD-Inverters applications.
LEM LF1005-S/SP36:
- Primary Current (I): Up to 1000 Amper
- Secondary Current (I): Standardized to either 1A or 5A, depending on the specific configuration
- Frequency Range: Typically, 50/60 Hz, but some models can measure a broader range
- Accuracy Level: Accuracy to 0.5 or Class 1 with indicating the precision of the measurement
- Application: Suitable for high-current measurements in industrial settings, large Kilo-watt Inverter-vfd
LEM LF505-S/SP27:
- Primary Current (I): Up to 500 Amper
- Secondary Current (I): Secondery current in CT 1A or 5A, depending on the specific configuration.
- Frequency Range: But some models can measure a broader range.
Common Features & Application:
