加拿大采购需求：霍尔效应传感器、功率传感器、产品

I'm looking to install an open-loop Hall effect current sensor that requires a ±15 V DC power supply for optimal performance. To ensure everything runs smoothly, I need your expertise on the appropriate power rating in watts that would be ideal for this setup. It's crucial that the power supply can handle the operational demands of the sensor without any issues. Additionally, if there are any specific recommendations or guidelines related to the installation or operation of the sensor that you think I should be aware of, please share those as well. This information will greatly assist in making the right choices for powering and utilizing the sensor effectively. Thanks!
