HALL EFFECT Open Loop AC/DC Current Transformers
QI-HSC2000
Pass-through opening 1040x360 mm According to the HALL effect principle
The HSCT sensors are used for all applications where direct current and variable frequencies (up to 20 kHz) need to be measured. For example, for battery monitoring systems (energy storage, UPS, emergency power supplies), speed controllers, power supplies for radio stations, power electronics, etc.
The output signals can be connected to special instruments, PLCs, etc.
By using the open-loop Hall effect measurement technique, they can be used with a core that can be opened, allowing the sensors to be easily installed without disconnecting the conductors. Removable screw terminals make installation extremely convenient.
