The new CS-100-AU current sensor is designed with low losses and high temperature stability toroidal ferrite core which allows working frequencies higher than 200 kHz at operating temperatures from -40ºC up to 155ºC.
The converters for hybrid and electric vehicles works at high voltage (400V) in the input site, which makes a must to isolate primary winding of the current sensor, directly connected to the high voltage circuit, from the secondary site, connected to the control circuit. Premo current sensor guarantees 3kV isolation and a creepage distance > 6.5mm.
A precise (Premo sensor precision 2%) sensing of primary currents let the system manage line and specially load regulation being able to set the workload and optimum working point either to maximize power or to minimize power consumption or dissipation ( Sensor dissipation less than 1W). Above all, a low DCR current sensor (Premo’s typical DCR is 0.5mOHM), is an efficient tool for ZVT and ZVS full bridge topologies to minimize stress in High frequency switching MOFET’s.
