Shim power




The SPS-6-5A is a shim power with high power capability. The SPS has six high current output channels and shim compensation on 3 differentials gradient control signals.

  • Up to 5A per shim channel
  • Shim compensation offset added on gradient control signals
  • I2C controlled for Chameleon system integration
  • High current precision
  • DC power supply, temperature and status monitoring
