1. Flexible adaptation of large current
Maximum current 700A (DC/RMS), current transfer ratio 1:1750, output range 0~400mA, suitable for high-power industrial scenarios.
2. Fast dynamic response
Response time ≤1μs, supports transient current capture, suitable for high-frequency power electronic equipment such as inverters and converters.
3. Wide temperature range stability
Temperature control compensation technology ensures no performance degradation at storage temperature of -25℃~+80℃, suitable for outdoor new energy power stations.
4. Low load resistance requirements
Load resistance ≤50Ω (@700A), reduces system power consumption, and is suitable for heavy equipment such as cranes and ski lifts.
5. Core application areas
Wind power converter monitoring, industrial robot joint drive, ship power system and aerospace ground testing.
