IsoBlock Q-4c

The IsoBlock Q-4c module was designed to isolate the voltage across cable segments of a superconducting magnet, as well as coils, half and full magnets. By placing multiple IsoBlock Q-4c sensors along the length of a superconducting cable, a time-of-flight technique can be used to locate a quench origin. Also, IsoBlock Q-4c sensors can be placed across larger symmetrical segments of a magnet to detect when the magnet starts quenching from superconducting state.

Three-Way Galvanic isolation

Each channel amplifies and magnetically modulates its input signal across a galvanic barrier. This results in 1200V sustained and 4200V surge isolation from channel-to-channel and channel-to-ground. In addition to that, each channel has a protection stage at its input that allows it to sustain voltage spikes generated during the magnet energy extraction. At the output of each isolation channel there is an anti-aliasing filter and a conditioning stage to output a ±10V signal.

Compact form factor

Of the IsoBlock Q-4c module allows users to setup high channel density monitoring systems, making it also ideal for extended magnet networks.
