Low voltage current transformer is a kind of equipment that can convert high AC current into low current that is easy to control. It has excellent performance and stable accuracy.
1. The product has novel structure, beautiful appearance, convenient installation, small volume, light weight, high accuracy and large capacity.
2. Simplify the system structure, reduce the cost and ensure high system reliability.
LM-0.5 series transformer is indoors type current transformer, is applicable for circuit of rated frequency 50Hz, rated voltage is 0.5kV and below.
It is used to transmit signal to measure meter, or relau protection, control device.And it isolates the measure, protect, and control device from high voltage.
It conforms to the standard of GB1208-2006.
Model No.
Normal operational condition
1. Ambient temperature: (-5 to +40)℃
2. Rated humidity: lower than 80%
3. Altitude: lower than 1000m
4. Location: indoors, without any metal dust or obvious vibration.
Main technical parameter
4.1 Rared voltage: 0.5kV
4.2 Rated frequency: 50Hz
4.3 Rated primary current: 10A, 12.5A,
4.4 Rated secondary current: 5A
4.5 Secondary load power factor: 0.8(delay)
4.6 Rated output: 2.5VA, 5VA, 10VA. When rated load is 5VA or 10VA, output Min load is 3.75VA. When rated load is above 10VA, Min load is quarter of rated load.
4.7 Accurency: 0.5
4.8 Insulation resistance: larger than 20M between primary coil and secondary coil and grounding.
4.9 Power frequency withstand voltage: power withstand voltage of of primary coil with secondary coil and ground can reach 3kV.
