- 假如系統還配備一個Senis 類比磁場傳感器，USB-6251也可讀回電磁鐵電流及電壓與磁場。
- 此外，還需要一個適用的dc電源供應器，例如Ametek SGA 160V，31A。為使機型3473-70電磁鐵以磁場的最大變動速率斜變，需要搭配SGA 160V，63A電源供應器。
- 完整的電腦控制型雙極電源供應系統：
- 將機型231HC及SGA DC電源供應器安裝在GMW-RC-1920台面高度的機架內，機架空間內放置GMW RMCS-P4機架安裝型電腦，便可構成一套運行GMW LVMCTRL LabVIEW控制軟體的完整電腦控制型電源供應系統。
- 關於機型231HC搭配GMW電磁鐵而展現性能的範例，請參考231H操作手冊說明。

- 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.
