GMW Bipolar Current Amplifier, 231HC

The GMW 231HC Bipolar Current Amplifier provides a fast response true bipolar current source of up to ±70A, ±160V for GMW Electromagnets including Electromagnets 5403, 5403EG, 5403AC, 3472-70, 3473-70 and 5451. The 231HC integrates a Copley Controls Gradient Amplifier Model 231HC with capacitor bank, auxiliary power supply, cooling fans and National Instruments USB-6251 data acquisition and control module in a 19 inch rack mounting cabinet. Either 16bit resolution USB or direct analog programming of the current output is available. The USB-6251 can also read back Electromagnet current and voltage and magnetic field if a Senis Analog Magnetic Field Transducer is included in the system.

A suitable dc Power Supply is also required, such as the Ametek SGA 160V, 31A. To ramp the 3473-70 Electromagnet at a maximum rate of change of field requires the SGA 160V, 63A Power Supply.

For a complete Bipolar Power Supply System the 231HC and SGA DC Power Supply are mounted in the GMW-RC-1920 Bench Height Rack. Rack space is available for the GMW RMCS-P4 Rack Mounted Computer to enable a complete computer controlled system running under the GMW LVMCTRL LabVIEW Control Software. Refer to the 231HC User Manual for performance examples with GMW Electromagnets.
